With the same set of images, attempting to stitch in Photoshop was hopeless: This was about as good a result as I could manage with AutoPano: I have tried the same with the fisheye but I have not mastered it - to be fair I have not spent a great deal of time at it. I take 13 photos at 30° intervals(first and last are 100% overlap) and Autopano just sucks them right up and makes a pano that needs minimal cropping. I have found that AutoPano does a great job of stitching. I've found the 20 f/2.8 on FF works very well for panos, these are with the camera mounted to a pano rail via an L-plate:ģ60° Pano from the top of Mount Tamalpias(North of Golden Gate) Thanks for that, I did see the corner sharpness disappearing on the defished images on the page to which I linked.įor some reason, my stitching of FF photos from my 20/2.8 has never been satisfactory, although my wife (the Photoshop Queen) does a much better job, which of course takes very much longer and forces me to admit my inferiority It is one of the supported lenses in the PTLens lineup. I’m considering using this lens, as the depth of field is incredible and, hopefully the distortion is correctable. The Dyxum user reports, few though they might be, are excellent except for geometric distortion. Strangely I’ve seen no real world user reports in the forums …good or bad. That is, it tests well in all but the Ken Rockwell review and I suspect he either had a bad example or was using infinity on the lens as infinity…it isn’t. Better than very well actually and it’s rectilinear and not a fisheye. It tests very well in the few reviews I’ve seen. One possibility is the ‘14mm f2.8 Samyang multi-coated aspherical IF ED MC’ lens (also Bower/Rokinon).

I have an a850 and the widest I go is 19mm and am also considering how to go wider inexpensively, yet maintaining excellent optical quality. You don't say what camera you are using or rather what sensor.APS-C or 35mm? That makes a huge difference, of course. I'd really like to get wider in a single image, affordably.what do dyxumers think represents the most economical solution in relation to the angle of view?
