Dear all, I'm coming from a 35mm digital system, and I'd always planned to get a large format camera to play with. My biggest motivator has been when taking a wide-angle landscape shot, wanting to make a large print and stand with my nose to the middle of the frame to get as immersive an experience as possible. My first attempt at this, with a 12 megapixel Nikon D700, simply ran out of pixels. Now I have a 36 megapixel D800E (36x24mm sensor, for anyone not used to dabbling in the toy formats), and I'm running out of lens instead - at least in the corners. I have a Nikkor 14-24mm, which is generally considered to be pretty competent, but it can't keep the corners (reasonably) sharp for me. The Zeiss 21mm is another option, as a lens with a stellar reputation, but even that seems to struggle in the corners on a D800E. So, before all the film supplies dry up, I'd been looking longingly at a cheap 5x4 (such as a Horseman 450LE, unless there's a reason I shouldn't go with one of these - I appreciate the difficulties of carting a monorail in the field, but I won't be taking it far and my 35mm kit is heavier...) and the second-hand market for, say, 47mm and 65mm f/5.6 super angulons. I'm assuming I'll be drum scanning the results. I'm now concerning myself with the corner performance of the large format lenses, assuming that I'm stopping down to f/16-ish. At least one review seemed reasonably complimentary of the 65mm (at least, the corner numbers for lppmm were reasonable), but a full analysis of these lenses is defeating my google-fu. Are either of these lenses (or any viable alternative) likely to do better than my 135-format options? I'm considering the 47mm to be vaguely equivalent in field of view to my 135-format 14mm, and the (cheaper) 65mm lens to be roughly 18mm equivalent in 135 terms (from the long edge in both cases). The latter may well be wide enough for most of my shots, but knowing the relative performance of the two would be helpful. Or shall I just give up and resort to stitching? Any assistance (other than "stop pixel peeping") is gratefully received - I'm a large-format novice.
