billib Posted October 22, 2011 Author Share #21 Posted October 22, 2011 Advertisement (gone after registration) Until I get a chance to use the Novoflex adapter, I'll blame the cheap adapter instead of the lens. Before y'all schooled me I was leaning toward the 8mm as being the problem. The exposure is a bit dark for what I had set also. Can't blame the adapter for that.....heck.

01af Posted October 23, 2011 Share #22 Posted October 23, 2011 How sharp is your lens if the best f-stop is used? Just how sharp is "perfectly sharp"? Well, umm ... okay, "perfectly" sharp maybe is an exaggeration. At the optimal f-stop (i. e. f/11 for my lens), sharpness at infinity isn't really perfect but it's perfectly usable for pictorial work. See the samples below, taken today. All images have been developed in Camera Raw 6.5. I removed some significant lateral chromatic aberration (R/C -50; B/Y -5) and applied some capture sharpening (Amount 35; Radius 0.8; Detail 65; Mask 35). Black surrounding cropped to square in Photoshop. Downsized to web size using resampling method "Bicubic sharper"; no output sharpening applied beyond that. Welcome, dear visitor!

billib Posted October 23, 2011 Author Share #23 Posted October 23, 2011 WOW, you went waaaaay beyond what I had expected. I can see now that some compromises must be made when designing lenses like this. I sort of expected your shots to be just a tad sharper. I haven't used my 8mm in years, no, decades. I find shots, such as yours, inspire me to use the Fish-eye more. I just remember the Nikkor as being sharper than the way it now appears. I guess the Leica is so unforgiving as well as digital in generalI, nothing can hide. I lost all of my photo's in a flood, so I can't check them for quality. I said " I " nine times.......oop's ten.......eleven. Oh my! Your shots were a big help,,,,,,,thank you! Link to post Share on other sites More sharing options...
ho_co Posted October 25, 2011 Share #24 Posted October 25, 2011 OT insofar as it's a full-frame fisheye, not circular image: Graham Watson, who shoots the Tour de France every year, gets very good mileage out of his 10.5 mm Nikkor by finding images where the lens' distortion blends with the subject, keeping the attention on the subject and not the lens. Specific examples from 2006 at Apple - Pro - Profiles - Graham Watson, Tour de France Gallery are: Stage 1, image 1 Stage 2, image 1 Stage 16, image 1 More info at :: GrahamWatson.com :: Graham Watson Cycling Photography ::.

01af Posted October 25, 2011 Share #25 Posted October 25, 2011 Generally, full-frame fisheye lenses—i. e. 15 - 16 mm for 35-mm format; 10 - 10.5 mm for APS-C format—are better and easier to use for pictorial work than circular-image fisheye lenses. The latter are mostly useful for scientific, industrial, or surveillance applications but rarely for pictorial work. However those who create 3D panoramas often find circular-image fisheye lenses useful. Link to post Share on other sites More sharing options...
wlaidlaw Posted April 14, 2013 Share #26 Posted April 14, 2013 Here is a shot taken with a Zenitar 16mm rectilinear fish eye on the M240. No alterations apart from conversion with ACR 7.4, a tweak on exposure and resizing in PS CS6. The patio at the bottom of the image is actually a straight line. When my wife saw the photo, she said: "Oh that looks quite good. I wish we had built it in a curve" Wilson Welcome, dear visitor!
