I don't have Stan's collected comments in front of me, so mine may overlap. I should add that I'm becoming a fan of using in-between focal lengths (like 30 or 31) to replace a pair (28 and 35):
From Pentax catalog: "The perfect solution for those trying to choose between the 35 and 28mm focal lengths. Light weight and ample lens speed." Tong Xu: "I recently conducted resolution tests between the K35/2.0, the A35/2.0, and the K30/2.8. The 30/2.8 is amazing. It outperforms the 35 2.0s at every respect. The K beat the A in center resolution at all f/stops, and tied it for corner resolution." (Results in Paul's file under 35 mm focal length.) Yoshi: "Hama's rectangular hood (52mm) is the best hood I have ever seen for K28/3.5, K24/2.8, K28/2, K30/2.8, K35/2, and K35/3.5 in my experience." Yoshihiko Takinami - . . .excellent optically; well corrected aberrations, very few distortion, very high actual/visual resolution, good color rendition. . .Yoshi: "I love this lens. :^) I like K30/2.8 better than any 28mm lens Pentax ever made. It's compact in size and very well built. > How about optical qualities: resolution, contrast, color, distortion, > bokeh, light fall-off, etc.? It has great resolving power visually/actually, excellent contrast and good color rendition. Distortion and light fall-off seem very slight, and its bokeh is really good. I have placed a sample photo taken with this lens at <http://www.takinami.com/yoshihiko/photo/gallery01/p&f0004.html> It was dim, cloudy morning I take that photo. The lens rendered the scene with quite impressive contrast and color, IMO. Yoshihiko Takinami Paul Franklin Stregevsky - This message is from the Pentax-Discuss Mail List.
