Yes, you can--adapters vary in price, from inexpensive to expensive--Google search and find all you want to know. Great camera BTW.

Okay, for added clarity I will post this shot too. This shot did not have a polarizer on the lens, nor a UV filter. I suggest avoiding UV filters on digital for optimum quality--my 2 cents. Anway, this shot is done on Full-frame sensor, with the 17mm Tamron f/3.5 Adaptall lens. Look at the deformation of color uniformity, ie, the left side of the frame has a much lighter blue than the right side. However, this has nothing to do with a polarizer; rather, it has everything do so with the composition's proximity to the Sun. In other words, the Sun is directly to the left of the composition, just outside of the most left portion of the shot. 17mm on FF is close to 11mm on APS-c.

This shot is @ f/3.5, or wide open on the Tammy adaptall.

Hi: want to offer my experience with this lens and a polarizer. I used a B & W (not cheap) Linear Polarizer &, even @ 10mm, never had deformations of color uniformity. The sky, especially in areas closest to the sun, will obviously show less intensity of the color blue--but this is visible to the naked eye alone. This discussion was already handled here in the club, with examples provided. I'll post 1 more example here for simplicity.
Sorry, about my late reply. I left Pentax over a year ago, pullled to the Dark side by the allure of full-frame and more lens options. I now have responsibilities to other forums, and I'm still trying to learn all things Nikon, even after a year. Feel free to ask more questions if you feel I can be of help--BEST!

Hi Amama:
I so much miss my days shooting with this lens. When I was active with it, I had good knowledge of all the major, as well as subtle differences between the 2 versions, If you carefully sift through this thread, you'll find discussion on the differences--in depth at times even. Off the top of my memory, so please do not quote me here, I'll try and quickly review some differences, aside from the obvious ones: price--speed--fixed aperture
3.5 version reported to handle flare a little better, though the 4-5.6 is no slouch for UWA. 3.5 versions has an extra A-Blade, given it an odd total, which makes for nice sun flares--distinct points. Reports (I believe SLR, for example) say 4-5.6 is sharper at the long end. Also, @ 10mm (according to Photozone) I believe the 4-5.6 version is better in the extreme borders while the lenses are close elsewhere @ 10mm. 3.5 version reportedly a little better with vignetting and with distortions. Feel free to Google subject and report back here anything you can add tot he discussion. Thanks and Happy Shooting!

Ah. music for my soul Tamia! The ADKs are so beautiful & I have so many spectacular moments spent there. The pics are splendid, as always. BTW, the native Americans believed Jewelweed had medicinal properties, specifically for Poison Ivy--if I'm not mistaken. I think it is still marketed today as a natural remedy. I really hope to make it back to my beloved ADKS soon, but am glad I have you shooting there and showing images here in the meantime!!! :) Thanks Tamia. :)

Hey there Tamia--I haven't been in the ADKs since Foliage time of last year, so this is a real treat for me--thank you! I probably will not make it up there again until this coming foliage season, so PLEASE keep posting when you can. I've always loved your work! Best!

Huh??? F/8 is the obvious point @ which APS-c diffraction sets in--ON ALL LENSES! The Sigma 10-20 (f/4-5.6 version, especially) is at its best. or dam close enough to it, @ 10mm (MTF scores @ 10mm & 14mm are too close to call)--this is some of the magic of the lens.
And Mr Designosophy is correct, corners are best starting @ f/11, continuing to f/13. Sophy=wisdom btw. ;) It is simply amazing what this lens can do @ 10mm, particularly when you look at its production date.

Falke: great sky + great sea=beautiful shot. :)
The soft but defined hues of greens & blues make it for sure.

Splendid work Mike and oh so shaaaaarp. So great to see my 10-20 in the hands of an artist now.
I particularly enjoy the way the letters are projected onto the inner wall, in the 2nd shot, as the sunlight works its magic on the window grafitti. Keep'em coming.
