Hello everyone,
I have a simple question. I recently picked up my first new lens for my first dSLR, a K20d. The kit lens was nice, but I found it weak at the edges. After a lot of research into affordable lenses, I found an SMC A 28mm f2.8 for 100 CAD.
So far I have been very happy. An improvement in bokeh and it is a full stop faster than my kit lens at 28mm. I bought it to get higher quality images, and less noisy indoor ones, at a low cost. I have been satisfied except for something new - a problem I do not have with my kit lens.
Here is an image I threw together. I know that veiling flare can be reduced by stopping down, so I stopped down to show you how it reduces flare in this situation. However, the veiling flare is not eliminated.
A couple of things: I realize this is a very chalanging shots for any camera and I also realize that I am essentially setting this lens up to fail by doing this test. But my kit lens does not exhibit this kind of flare and I would like to know why I am seeing this, and if I should be expecting to see this.
In many cases this lens performs better than my kit lens, but if there is anything I can do to tackle this specific problem, I would like to know what it is! The lens is free of grease and other residue as far as I can tell.
Is there something wrong with this lens or should I expect this kind of performance from a 1980's SMC A prime?
P.S., A confession - I actually like the way this glare can look - sometimes. But I want to know how to get it under control.
