If the APS-C sized sensor is so inferior to the full frame, as many people claim,why is it that Canon just introduced the EOS 7D?

Hi Pentaxian friends.

If I had a dollar for everytime someone told me that the APS-C size sensor that Pentax uses is not as good as a Full Frame sensor...well I would be rich by now. We hear the argument all the time that Full Frame is the only way to go and that "my next camera will be a full frame". The fact is that only 5% of the camera sold worldwide are Full Frame. That's not a big market and it is a market mostly used by Pros. The prices for Full Frame sensors will remain high because of the cost of making larger sensors from the same standard sized silicon wafers.

Why would Canon introduce a new (1.5 crop factor) DSLR? The EOS 7D is indeed an APS-C. DSLR. Since Canon now adopts it, does it make it any better? Furthermore, their new sensor is a CMOS with 18 mega pixels. I thought that the optimum and maximum effective mega pixels on an APS-C sensor was around 12 mega pixels!

It is obvious that Canon really believes that APS-C is the way to go for the consumers (the 95% of them that don't purchase Full Frame DSLRs).

To me, that reinforces my loyalty to Pentax. Why would a giant like Canon revert to APS-C sensors, just like Pentax? I bet you that sites that favor Canon (we all know who they are) will now praise the virtues of Canon APS-C sensors...Hello! Isn't it what Pentax has been doing all along?

Thanks for reading,

Well, releasing 7D doesn't mean Canon isn't going to pursue it's full frame lines too. It just means there's still place on the market for high end crop cameras. For great majority of users FF just doesn't bring enough advantage to justify the costs.

That's just a way to milk the FF buzz since many clueless people are going to get this camera because they'll think it's the new 5D without even knowing what is or isn't FF. I myself know two people like that.

I never understood nor understand now the big deal about the full frame sensor.
You lose dof and get a bit of high iso back. And that iso could be higher if they wouldn't try to put more pixels on the sensor.
I'm glad that they didn't up that amount in the k7 and made other enhancements.

I simply love the 1.5 crop factor, it means that I can have a 300mm that works as a 450mm with extra dof, and I don't have to carry a f4 450mm with me.

Again I don't understand the need for a ff-sensor.

come on... Yvon, do you mean canon FF bodies discontinued? ... canon, nikon and Sony all have got more than one FF digital body. Leica has got one now.
Why some Pentax users shouldn't?

I really don't like unreal extra DOF and less FOV.

I want 43mm or 50mm as my standart lens and 85mm for portraits with FF DOF and FOV, nothing less nothing more.

...plus two cents from me:))

Hey guys,

Some of you are getting me wrong. I'm not taking anything away from the FF cameras. They are producing better images with less noise. However the FF DSLRs are about 5% of all camera sales. I just think that's it's strange that Canon would revert to an APS-C camera after all reviews and comments from all the Canon fans all over the world. APS-C is 1.5 crop Canon did make APS sized DSLRs but it was the APS-H with a lesser crop factor. II also believe that now that Canon has produced this APS-C camera, it will suddenly be the favorite sensor size that reviewers all over will prefer. That's the power of being No.1.

Yvon,

I'm not sure what you mean by this. Canon has made 1.6x APS-C cameras for a while, with some APS-H cameras appearing in their "pro" range.

But back to the original post, I too am happy that Canon has released such a high quality APS-C camera. It means they do not consider APS-C to be a "beginners" format, which is the status some Canikon shooters have been trying to give it for some time.

Like you say, even with FF camera prices coming down in the last year, the vast majority of DSLR sales are still from APS-C cameras, and many good photographers still prefer APS-C for its many benefits.

I hope Pentax will continue to provide advanced cameras in the APS-C format, even if they do eventually produce a FF camera. The idea that the best camera in a range has to be FF is wrong in my opinion. I think there should be a top of the line FF, and a similarly spec'd (yet cheaper and smaller) APS-C right beside it.

I'm a Pentax user and fan: K-7 and 20D; I started with the K10D. I find the lack of market support for the Pentax very troubling and frustrating. For instance, I have to purchase every single lens or body I need though I made not use them often enough to justify me purchasing them. Brands like Pocketwizards II do not even develop dedicated TTL radio transmitters for their receivers like they do for Nikon and Canon therefore TTL for off camera flash triggering is out the window for Pentax. I can't rely on Pentax's optical triggering, and its operating distance is a liability. I'm a great fan of Pentax, but, with lack of market support, I'm seriously thinking of doing the unthinkable: switching brands to the "other two" names in the business in order to enjoy broad market support. Please, if anyone knows a place that rents lens for Pentax, and knows how to use TTL with pocket wizards please help. In conclusion, I notice market support dwindling for this great brand. Stores like Ritz camera or Calumet photo that initially carried the brand have dropped it entirely; I bought my 1st DSLR a K10D from Calumet Photographic. Is there light at the end of the tunnel?

Miserere said...

ToKs,

I assume you mean P-TTL, not TTL. There would be little point in transmitting TTL info to an off-body flash. In any case, most photographers using off-camera flash use the strobes in manual mode because they want full control of their light; I see very little benefit to being able to use P-TTL for off-camera lighting.

As for renting Pentax lenses, if you are in the US you can do so via Camera Lens Rentals.

If FF is 5% of the DSLR market - is that units sold or revenue?
Because if it is revenue 5% then units is more likely 2%.

Just curious!

Yvon Bourque said...

Kym,

From my source, it is roughly 5% on units sold. Seems like everybody is talking about when Pentax will come out with a FF camera. They won't. Look at Canon, they just introduced the EOS 7D which is an APS-C (1.5x). There must be a market for APS-C otherwise a giant like Canon would not make such move. Look at Nikon D300 and D300S...APS-C!

Pentax will likely introduce the 645D next and will jump ahead of the FF with an even bigger sensor and will probably sell it for less than the Nikon D3 or Canon EOS 1D Mk III.

@Miserere thank for the tip about lens rental, but I know about that one already. what I mean is physical stores I can walk into test the lens, body, strobes etc and be able to rent them. I did find out about a store or two that do this in NYC after attending a Pentax conference. A bit pricier than rentals for the other brands but, hey, it's better than nothing.. thx again
