'An uncoated lens isnt good for color'.
What this debate really comes down to is making prints, apparently. As far as the rest of the photo process, its almost the same. It uses lenses, light proof bodies, apertures and shutter speeds....
Its easy to visualize why the light falloff exists off axis. Imagine your eye at the center of the film plane, looking at the aperture hole. It looks more or less round, doesnt it? Now move your...
A little soft at 8X? Thats not too bad. After all, its the equivalent of a 32x40 print. See how sharp 35mm would be at that size!
I shoot in color only (in LF). I like color. I shot lots of B&W when I first started in photography some 30 odd years ago, and I enjoyed it, but then I discovered Kodachrome, and rarely shoot B&W...
I'm suprised also. I would expect the yellow flower to indicate a faster shutter speed than the gray card, all things being equal. This is the reason I almost always use incident metering. I find I...
Maybe having the best one you already have overhauled would be cheaper. The 127 Ektar is very capable. Check with Steve Grimes about a CLA here: http://www.skgrimes.com/
Use the 203 Ektar. Nice lens, and long enough to reduce perspective distortion, too. If you have an old skylight filter laying around, a few drops of clear nail polish on the surface (or even a bit...
Lens design is not really of any importance. Like you mentioned, image circle is the most important (it must cover your film and provide for movements). You will find that the more modern designs ...
Check this site for good information on lens quality: http://www.hevanet.com/cperez/index.html It seems it is quite difficult to find a bad lens for LF work. The one bad example Terry and others...
The Ektar is an excellent lens, and performs very well. The Geronar is a budget 3 element lens, but will work well also. The two newer lenses should also perform very well, and probably have more...
I like the neutral palate of Kodak EPN, which is designed for accurate color reproduction. I find it works best for me when exposed at its rated ISO of 100.
Chaco canyon, northeast of Gallup is a great place to get good photos. It should be on your map.
As the diagonal of 4x5 is 168mm (minus the hold down rails, etc), I would think that when focused at infinity, you would have no movements. However, you will probably never be focused at infinity, ...
I use a lot of Provia, and I like it. It serves 90% of my LF needs. I dont think you will find that it needs anything unusual in the line of filtering. Treat it like your standard reversal film,...
The Speed Graphic is limited to about a 75mm minimum because of the extra thickness of the focal plane shutter mechanism. The Crown, with no FP shutter, can use a shorter FL lens.
I agree with Simon. The differences in your choice of film will be far greater than the differences in modern lenses. Its rare to find a LF lens that isnt 'sharp enough', even with older vintage...
Go with the Speed or Crown (or Super). Low priced, rugged, and capable. I love my SG. If you get a Speed, dont bother with the focal plane shutter. Just leave it open, and use the leaf shutter in...
Wollensak made lots of LF lenses in thier day. I have a 162mm Graphlex Optar (made by Wollensak, and the same as thier Raptar), and it performs quite well for its age. While not as sharp on the...
I think I remember someone saying that the Komura lenses are Congos. If so, you can find info on it here, as well as a sample shot.

Images I have...
Angle of coverage of course determines the image circle, so the two terms are directly related. As Pete mentioned, the image circle specified is when focused at infinity. As you focus closer, the...
I scribed lines on mine with the blade of an exacto knife. I used a straight edge lined up on measured tick marks, and went over with the exacto a number of times until the 'tooth' was removed. The...
By all means, shoot color. I have an old uncoated 162mm Optar, and it produces wonderfully saturated chromes. It does suffer from a lack of contrast in a backlit situation, but that is only a small...
I have seen good results from Congo lenses too. I think a lot of people who bad mouth them really have no experience with them, and just repeat what they have read from various sources (if its not...
These images were not printed. These are the image files, so printing has nothing to do with it. As far as scanning the film, if enough resolution was used to reveal the dye clouds, I dont see what...
Check this site for some good real world testing of lens resolution : http://www.hevanet.com/cperez/index.html
Steve, you apparently did not check out the url. They give all details of the images, and the scanning resolution (5700 DPI) on an Imacon Precision II Film Scanner. You can see the grain (or dye ...
Sharpening wont create detail that isnt in the file. I didnt say sharper (but they are), but do indeed contain more detail. Like it or not, digital is coming of age. Digital solutions for LF are...
Check this site for a comparison of various digital cameras to each other, and to 35mm Kodak E100 slide film. It seems that the 6MP imager used in the Kodak 660 and the Phase One med....
I agree. Use the lens you have until you know you want to stick with 8x10. AA once said he prefered having just one lens. 'If I have several lenses, then I never have the right lens.'
David, do your shutters actually wander that much? I find mine to be quite stable.
I have used shutters that were in storage for far longer than that (20 yrs), and they work just fine. Go thru each speed a few times, and see how they sound. A few chromes will tell. If it seems ...
Using a larger aperture means you will have to use tilts or swings to maximize your DOF. Position your subject (rifle) so you can take maximum advantage of tilts. Are you using strobe? If so, maybe...
The pro market is going digital. Unless amateur shooters want to take up the slack in sales, this is what you can expect. You think the film selection is poor now, wait another 10 (or maybe 5)...
I would recommend shooting print film for the wedding. Try some Fuji NPS (ISO 160) or Kodak 160NC, or Kodak 400NC (ISO 400) if more speed is needed. These films are made for portraits and weddings,...
Probably just for the convienience and economy of shooting roll film.
I did this to my 162mm Wollensak (Graphlex Optar) by taking a slightly larger step up ring and filing down the threads until I could force it into the threads of the lens. Its more or less...
In transparency film, Kodak EPN has the most accurate color balance. Fuji Astia (and Provia), are excellent films, but with less color accuracy than EPN. If long exposures are required, tungsten...
The 55mm is about 1 stop down at 50mm from the optical axis at F22, so the falloff would be noticable on 6x7, even with no movements, even more so on 6x9. This is normal for any lens in this focal...
David, F11 is F11 reguardless of format. F ratios takes the guesswork out of it.
