Hi Pentaxian friends.

There's almost too much talk about the upcoming Pentax DSLR, the K7 or K-7. I got out of the rumors frenzy and went out with my current K20D (still a pretty good DSLR) and the new DA 15mm Limited. Above are just a few images. I used a 77mm Circular Polarizer handheld in front of the lens. I adjusted for contrast and brightness in Lightroom 2.3.

Thank you for looking,

It all started with a field trip to test the DA 15mm limited...

Hi Pentaxian friends.

Yesterday, Monday April 20, 2009, I woke up with the intention of going to the San Bernardino Mountains and test the ability of the new Pentax DA 15mm f/4 ED IF Limited lens. The wild flowers are emerging everywhere and I thought they would be good subjects for field testing this promising new lens. I did indeed drive to the mountains with my Jeep and brought the K20D with the 15mm lens and the K200D with the new DA* 55mm lens.

It was our first really nice day this year and the thermometer reached over 90 degrees Fahrenheit. I really had good intentions and I had the cameras and lenses with me, but once I reached the foot of the mountains, it seemed that it would be so nice just to drive up to the summit with the jeep. The lens testing became secondary. I took plenty of photos, but none were intended to test the lens.

As I was climbing the mountain with the Jeep in "four-wheel-drive" mode I kept thinking that I still had not named my Jeep. It is customary to name your Jeep. Men usually give a female name to their Jeep and women usually give a male name to their Jeep, but not necessarily. Well, I knew my Jeep was a "she" because when I bought "it" I was told "she" liked to climb.

My two principal hobbies are photography and four-wheeling. I wanted a name that would reflect both hobbies. The Jeep came unaltered from the factory and we worked on improving it and finishing it the way it is today. We lifted the whole Jeep 6", put a new motor, new coil-spring suspension, 35" monster tires, etc. It's sort of parallel to digital photography, whereas your original pictures can be taken in "RAW" format and after working on the images, they can be saved in "JPEG"format. My Jeep was originally in "RAW" form from the factory but after altering it, it becamed like a "JPEG" format. So I decided to name my Jeep Miss" J. Peggy". This is an acronym for "Jeep Photographer Environmentally Going Green...Yes!". For short, her nickname is really Miss Peggy. It fits both of my hobbies and my views about the environment. I always drive on assigned trails, and usually pick up the trash that other people left behind. It's our only earth and we better take care of our little planet.

So, although the photos here were taken with either the DA 15mm limited or the DA* 55mm, they are not what I would have used to field test the lens and draw my conclusions. You can still see the resolving capabilities in some of the pictures. I guess I will try testing the lens this coming weekend, and maybe I shouldn't drive Ms. Peggy. She might distract me from my mission by taking me to new places that only she can take me. I could be distracted again and forget my mission for the day.

I swear that I saw Ms. Peggy smiling. I got the proof right here!

The San Bernardino Mountains are about 60 miles North/East of Los Angeles.

This is where we started our escapade, Elevation 2,000 ft.

The vegetation changes according to the elevation. These wild flowers were starting to bloom between 3,000 to 4,000 ft.

Here we are at about 4,000 ft elevation and we took the wrong direction. The trail ended here. Turning around is harder than it looks. I was on top of a ridge.

Back on the trail and climbing. We're at 5,000 ft.

Time for a rest. We are at around 6,000 ft and the air is fresh and the temperature down in the seventies. No city noise, just the chirping of birds. It's beautiful up here.

We are on top. The mountain with the snow cap is Mt. San Gorgonio at an elevation of 11,499 ft.

It's time to go home. You don't want to get stuck up here without camping gear.

It still a bumpy ride going down...

and you can't go there with your car...

but we'll be back soon.

Thank you for reading.

Yvon Bourque and Ms. Peggy!

Pentax DA 15mm f/4 ED Limited lens arrived today.

Hi Pentaxian friends.

I received my Pentax DA 15mm f/4 ED Limited lens. What a beautiful little lens. I like big lenses and big cameras, but lately, I have been so impressed with the Pentax Limited lenses, that I got to have the whole series. I still like big cameras and lenses when I go for a planned photo shoot, but for traveling, I am now favoring the Limited lenses with either the K2000 or the K200D without the handgrip.

The Pentax prime lenses have a very good reputation.

I will test the lens in the coming days and will report my impressions on this blog.

Hi Pentaxian friends.

As I wrote in the previous post, I have not been able to write on this blog as much as I had intended during the PMA show. However, here are a few pictures of some of the equipment I had the pleasure to hold and use while at the PMA. Again, I will post my comments and impressions once I get back home.


You are going to love the new 55mm f/1.4 SDM lens and will be blown away with the new 15mm Limited. I will post pictures taken with them later on, as well as pictures taken with various lenses and the new X70.

Thank you for reading,

Setting Up a Prime Lens Kit with Pentax

by Miserere


Ever noticed how many things in life come in threes? The 3 Stooges, the 3 Musketeers, the 3 Tenors, the 3 Wise Men...and your friends will always give you 3 cheers. So too do primes come in threes.

Last week I wrote about my love of primes, and hopefully I got some of you to put away your zoom lens for an afternoon and go shooting with a prime instead. Did you have fun? Did you enjoy shooting at lower ISOs? Did you show off to your friends because their primes weren't image-stabilised while yours were thanks to Pentax's in-body IS? I hope you replied "yes" to all of the above.

Let's make it clear that I am not advocating that you throw away your zooms, only that you broaden your horizons...and your tools. There is a time for zooms, and a time for primes. When you've spent enough hours shooting both you will know exactly when you need, or want, either of them.

But how do you go about setting up a 3 prime lens kit? With zooms, you just choose a wide angle zoom (18-55mm, 16-45mm, 16-50mm...) and a telephoto zoom (50-200mm, 55-300mm, 50-135mm...), with the depth of your pocket being the determining factor as to which ones you pick. How could that be easier!? Primes are another story, because there are many focal lengths and apertures to choose from.


Superman says 28mm is normal.

Back in the day it wasn't so difficult. Most photographers had a wide, a normal and a telephoto lens. Wides were usually 24mm or 28mm; normals were somewhere between 35mm and 55mm (depending on what "normal" meant to each photographer) and telephotos were between 100mm and 135mm. The rule of thumb was to pick focal lengths that were about 1 stop apart in length, such that each lens had half the field of view of the preceding one (which is double the focal length). Possible combinations following this rule could be 28mm, 55mm and 105mm; or 24mm, 50mm and 100mm. Then, as now, which particular flavour you chose of each lens depended on your pocket. If you could afford it, you would have picked a 28mm f/2 and a 50mm f/1.4. More thrifty photographers would have gone for the more affordable 24/28mm f/2.8 and a 50mm f/2.

In 2001 Pentax made the choice of a prime trio easy for those who could afford it by issuing the 31mm f/1.8 Ltd., last of the three FA series Limited primes. Those who wanted the very best in construction and image quality could buy a 31mm f/1.8, a 43mm f/1.9 and a 77mm f/1.8. While these numbers might seem like they were pulled out of a bingo ball after too much sake was drunk at a Pentax New Year's party, they actually do make sense. 43mm is the length of the diagonal of 35mm film, which makes this limited the epitome of "normal" lenses. 31mm offers a FoV that is about 1-1/3 times wider than 43mm, while 77mm is a little over 1-2/3 narrower than 43mm.


50mm is the king of primes.

The problem is that all these focal lengths I'm quoting are for 35mm film. What about those shooting digital Pentax? Fret not, there is still hope. Pentax thought of us APS-C guys and introduced a line of DA Limiteds: 15mm, 21mm, 40mm and 70mm; and all but the 15mm are pancake lenses! While the 40mm and 70mm lenses are longer than their FA Ltd brothers (61mm and 107mm 35mm equivalents), the 21mm is a 32mm-equiv. However, the DA Ltds. are actually closer to the classic 28/55/105mm trio (in FoV, when mounted on APS-C) than their FA counterparts and are more versatile for it. The upcoming 15mm f/4 Ltd will provide a 23mm-equiv. FoV in a small package, for those that want something wider than the 21mm f/3.2 Ltd.

OK, but how about those who are on a budget? Again, Pentax is here to help you, because you can use Pentax's backwards compatibility to your advantage. There are literally tens of thousands of K, M, and A prime lenses out there in the used market looking for a new home, and unlike with other brands, they will work on your Pentax DSLR (although some functionality might be lost, you will never lose the ability to meter, even if it means pressing an extra button). Claim a 28mm f/2.8 for well under $100 and use it as your normal lens. Get a 50mm or 55mm as your short tele lens, ideal for portraits on APS-C. If you don't want to jump for a new FA 50mm f/1.4, get an M series version. If you want the versatility of being able to use Av or Tv, why not try the crowd favourite SMC-A 50mm f/1.7? (Just be sure to enquire as to the health of the aperture ring, because they tend to break easily for this particular lens.) If you want wider angles than 28mm or 24mm, Pentax can offer you the K or M series 20mm f/4. And don't be shy, there are also plenty of 3rd party options available. And remember, while these older Pentax primes might be old, they are made of metal and glass, have long focus throws, and are a joy to use. Once you get one, you might find yourself sitting in front of the television turning the focus ring this way and that, just because it feels good.


135 is not just an abstract number.

And what's my prime trio of choice? 24/28mm, 50mm, 135mm. Yup, I might be shooting APS-C, but I still like the old classics. I guess I'm not really a wide guy when it comes to photography. I can't sing much either.

To finish off, I want to remind you all that Pentax has always been known for its marvellous primes. You will find many photographers who will tell you the only reason they chose the Pentax system was because of their prime line-up. Even today, Pentax are continuing to release primes while other brands are busy churning out only zooms.

So be true to tradition and start doing your math: figure out which is your normal focal length, then divide and multiply by 2. Now get on the internet or visit your local pawn shop and get yourself a nice trio. They may not sing like The 3 Tenors, but they might make you sing when you see what you can do with them.

When you're done with your photography session, don't forget to give yourself 3 cheers.


Thanks for reading.

Miserere's Musings on Pentax's New Releases

Hi Pentax friends,
Today, Friday September 26, 2008, Miserere gives his opinion of the new Pentax releases and his future expectations. Give us your opinion in the comment section. However, any bashing will be removed as we want this site to remain friendly. We need constructive comments and, by-the-way, Pentax USA do read this blog regularly.
Regards,
Yvon Bourque
________________________________________________
Like it says on the can, this week I’m going to give you my opinion on the new equipment Pentax announced at the Photokina 2008 held in Cologne, Germany during 23-28 September. I won’t delve deeply into technical specifications as that is not the object of the article. For specs, please read Yvon’s thorough post earlier this week.

K-m/K2000 DSLR + DA L 18-55mm and 50-200mm Kit Lenses

This is Pentax’s first true entry-level DSLR offering ever. Let me start off by saying that I’m bored of reading people’s comments about this camera complaining that it doesn’t have a top LCD, or that it only has 5 AF points, or that (are you ready for this?) it is too small. Seriously, enough already. Pentax has had a problem with its previous entry-level cameras (like the K100D and the K200D) because, although they were priced similarly to the competition’s entry-level offerings, the Pentaxes were higher spec’d and of higher general build quality. While this is great for advanced amateurs migrating from film cameras and the braver P&S enthusiasts, I feel many people looked at the K100/200D and thought “that’s too professional for me, I won’t know how to use it” and bought a simpler camera from the competition. With the K-m/K2000 Pentax now has an undaunting camera to offer those moving up from their P&S. This will bring more people into the Pentax system, and more money into the Pentax pockets, which will translate into more products for all of us down the line. If this camera is simple it is because it is not meant for advanced users! Let’s not criticise the camera for being too basic, because that was the goal all along.

I’ve also read complaints about the new DA L lenses because they sport plastic mounts. Again, I don’t see a problem with this. They will only be sold as a kit with the K-m/K2000 and the target demographic is unlikely to be changing lenses all that often. If it cuts costs and increases Pentax’s profit margin, I’m all for it. If Pentax wins, we all do. Props also to Pentax for including an external flash in the kit.

DA* 60-250mm f/4

This lens was announced just before the Moon landings and Pentaxians everywhere got very excited. Now it’s being announced again, and we’re told this time it’s for real. In case we didn’t believe them, the MRSP has been set to $1,500. I really hope this translates to something like $1,200 street price, although even then I think Pentax have shot themselves in the foot. Faced with the decision of buying an f/4 zoom (which is not fast on an APS-C camera) for this price, or an f/2.8 zoom in the 70-200mm range for $700-800 from Tamron or Sigma, I believe many will choose the latter. I am aware many people thought this lens would be around $800-900, and I was one of them. I’m sorry, Pentax, but I don’t understand this price. If anyone can explain to me how they justify it, please leave your theory in the comment section. For those that still want it, you have until November or so to save up the cash.

Please understand that I am not complaining just for the sake of it. There were so many people waiting years (literally) for this lens that have been let down by its exorbitant price, that I truly believe Pentax is going to lose a lot of money in missed sales because of it. Even at $900 it would’ve flown off the shelves.

DA* 55mm f/1.4

Continuing Pentax’s crusade to reproduce all the classic 35mm focal lengths they have released an 84mm f/2 equivalent in the form of an SDM, weather-sealed 55mm f/1.4. I am hoping the quoted price of $800 becomes $600 when it hits the streets. Although it might seem high, when you consider this is a top-quality lens, and Pentax’s first SDM short prime, it isn’t that high, especially if the image quality is as good as we’ve been promised. I am looking forward to receiving a copy on loan from some kind soul so I can review it on this blog (seriously, you’ll get at least 5,000 Karma points for lending me the lens). I use my FA 50mm f/1.4 extensively for portraits and low-light photography and would love to compare these two lenses.

Will a DA 90mm f/2 be next...? (A guy can dream, can’t he?)

AF160FC Auto Ring Flash

This came out of nowhere! Nobody was expecting a ring flash for the macrophiles, but it makes sense to release it shortly after the introduction of the 35mm Ltd macro. I am very glad for this announcement as it proves Pentax is moving forward and thinking like it is staying around a while. A ring flash is not an item you release when your company is in crisis, so I see it as a good omen.

DA 15mm f/4 Ltd

There was much speculation as to which way Pentax would go with this lens since they announced their new 15mm a few months back. I think the consensus was “we don’t want another huge lens like the DA 14mm f/2.8”, and Pentax delivered. This is a Limited lens that continues the tradition of compactness that characterises the line and which appears to be no larger than the 35mm Ltd macro. While the lens is still under glass at the Photokina, I believe it should be on shelves next Spring. No indication of price yet, but if it is priced similar to the 35mm Ltd, I doubt Pentax will be able to manufacture them quick enough to meet demand.

DA 1.4x Teleconverter

Finally! The last time Pentax introduced a 1.4x TC was for the A series lenses back in 1984. I’ll do the math for you: that was 24 years ago! Pentax has never had a teleconverter that would drive auto-focus lenses (the 1.7x AF TC was a compromise), so users had to rely on third party TCs. Some of these have become so coveted (like the Tamron MC4 1.4x TC) that they sell for several hundred dollars on eBay because they are no longer manufactured.

Again, I am happy that Pentax is releasing this TC (and I’m hoping a 2x will follow) as it shows a commitment to offering a full lens system. It is also under glass at the Photokina and no pricing has been announced, but my guess would be around $300. It should be out in the Spring, just in time for the good weather in the Northern hemisphere. I can imagine there will be many DA* 300mm lenses out roaming the parks with this TC attached.

K30D DSLR

Maybe the biggest star of the Pentax Photokina rollout was the missing camera: the K30D. The second photo in this sample gallery is made up of 17.4 million pixels; it grabbed Pentaxians’ attention when somebody noticed the size and got the rumour mills working overtime (interestingly enough, the full size photo no longer seems to be available). Many saw it as proof that the K30D, with a 17.4MP sensor, would be announced at the Photokina, while others speculated that it heralded the arrival of the much-awaited Pentax full-frame flagship (even though the images were allegedly taken with the APS-C-only 35mm Ltd lens). Some are claiming that the image was simply uprezzed from a standard K20D file, but Pentax isn’t doing anything to clear the fog.

While I can understand the appeal of a new top-of-the-range camera, we should remember that the K20D only started shipping around March/April this year. It is much too early to be releasing a new flagship now. If the successor of the K20D is in the works, then it will be announced at the PMA in March 2009, although I wouldn’t be surprised if we heard nothing until later in the year.

Pentax USA Releases

On the local front (for those living in the USA), Pentax will release a leather hand strap and a case for the Limited lenses. Not owning 3 Limiteds, I am more interested in the strap, as I often wrap the neck strap around my wrist in several loops when walking around with the camera, all the while wishing I had a better system. This might be it.


These have been my opinions; some good, some bad, but all mine and not necessarily shared by anyone else on this blog. What did you like from the new stuff? What didn’t you like? Let us know in the comments section. Just remember to keep it civil. After all, Photography is just a hobby, right?

Right…?
