I thought I would go ahead and make a dedicated thread with some photos from this new lens. I hope others feel free to add their own photos as well as they get their copies. I'll just say up front that I am not a professional and not a great lens tester. Photos will probably not be perfect, but hopefully they are good enough to show a little bit of the features of the new lens.
I guess a few comments about the build. It is a big lens -- bigger than the 16-50 f2.8, which is pretty good sized in my book. Of course, it is an f2.8 lens that covers a full frame image circle. Not surprising, but it isn't a small lens. Auto focus is silent and feels fast. I know Pentax listed this as an "SDM" lens, but it feels faster than the SDM lenses I own (16-50, 50-135, 55, 200) and it seems to lock focus quickly on a K3. The zoom ring is in front of the focus ring which is something that I am not used to and took a little bit of adjustment. I did not do any manual focusing, so no comments really on that aspect of the lens.
This is my son at 70mm and f2.8 -- normally I'd crop this a little bit, but I thought I would leave it as originally shot so folks can see the whole frame.
70mm and f4
A few shots that look a bokeh.
70mm f4
70mm f2.8
70mm f2.8
A couple of landscape shots.
24mm f4
63mm f8
A couple of shots looking at flare. I would say it is better than the 16-50 when it comes to flare (not hard to be better than that lens), but not nearly as good as Pentax primes (also not unexpected). I would normally have fixed the flare in these photos, but I left for the purposes of showing what it looks like.
24mm f2.8
24mm f4
I hope these photos are helpful and again, I apologize if the photos weren't perfect, focus points weren't right, etc.
Edit: I will mention that I did make a review in the Pentax Forums' review section and have a lot of images there from both the K3 and K-1. Several members have PMed me as well and I am glad to answer any questions that I can with regard to its performance versus other lenses that I have used.
