Originally posted by Pentaxor I see. I want to ask some question regarding your Sigma 10-20.
setting aside the wide aspect of the lens, how do you find the colors, contrast, and sharpness? because those 3 are the most important thing for me in getting an ultrawide lens. I do mind and hate dull colors but wouldn't mind aperture speed.
and why didn't you get the 85 if it's that good? you can set it at f2 anyways, right? and a 21 doesn't seem to be a good choice since you have a 10-20. maybe a 24 would be more ideal. I just don't like the 28 at all(except the K f/2), that's why I'm not considering it.
Pentaxor,
I have 24 (Sigma) at the moment, and in terms of FL I agree with you. 24 is better for my line up than 21. But I'm not happy with the IQ of the 24. I gave it a fair chance and it disappointed me. So I laid it aside. Then I took it out again. I thought it's OK until I started to process pics that my wife took on the same day with 31ltd.... Man, that was it. I'm out for a new lens. 21 vs 10-20? One is big bulky and superwide, other is lightweight. So if I'd be going light then 21 would get the call....
re: Sigma 10-20. I believe I have a great copy. I'm not fussed about AF and it's issued. 98% of my shots with that lens is @10mm f8/11, MF on 1m mark. Because of the huge FOV the metering with this lens is tricky. I stick to M mode, take few shots to determine the right exposure and off you go....
- all following relates to settings as described above -
Sharpness:
at f8 - 11 the lens is great! Coupled with K10 it delivers a lot of detail. On K20 (GX20 in my case) it it's nothing short of superb. At f5.6 most of the frame is still great and sharp, but extreme corners do lack a bit...
Color and contrast:
It's definitely "colder" than Pentax lenses. But if you nail the exposure, it has great contrast and punch to the pictures.
All in all, I think for the price this sells, you can't go wrong with ti!
Here are some examples:
