Here are some pictures taken with the SMC FA 50mm f/1.4. I used the K-50 and the K-5.

Hi Photographer friends,

We are currently in San Diego with our RV setup. We will be in the area for one Month as there are so much to see here. We drove to Ocean Beach this past weekend and I brought one lens only. I brought the SMC FA 50mm f/1.4.

I wanted to get as much bokeh as possible on some images, so image 1 and 2 were taken at the f/1.4 aperture. The K-50 did a good job as I can't see any differences between it and the K-5 images. The rest of the images just show the K-50 rendition.

v Choosing a large aperture limits the depth of field, making your subject stand out with a blurry background and foreground (bokeh). This is very useful for portraits. This depth of field is proportionally accentuated with telephoto lenses. However, it may require a fast shutter speed or a slower ISO.

I don't know what kind of bird this is, but it was watching our every move at this outside Cafe, to pick up the left over. Notice his one leg partially cut-off?

This surfer chopped VW bus has certainly seen better days.

I will have a lot more pictures of the San Diego area in the weeks to come.

Apeture scale explained

The aperture, being the lens diaghphram opening, lets more or less light pass through the lens. The f/number (aperture opening) is proportional to the ratio between the lens focal length and aperture diameter, which is proportional to the square root of the aperture area. Big lingo, but what does it mean for you? Well, lenses are usually marked with the f/numbers ranging from the largest aperture to the smallest aperture.  For example, a typical  lens could have an aperture range of  f/1.4 to f/32.  In this example, the largest aperture would be f/1.4 while the smallest would be f/32. Have you noticed something a little surprising here? The larger the number is, the smaller the aperture is. You need to remember that. Furthermore, each (f-stop) number  to the right lets twice the amount of light in as the (f-stop) number to its left  and each (f-stop) number to the left lets half the light in as the (f-stop) number to its right. For example, f/4 lets twice as much light in as f/5.6 but only one half the light of f/2.8, and so on. One unit of increment in aperture is called a stop.

To get great Bokeh, use the largest aperture of the lens being used.
