You guys are all wonderful, and you've gone to great lengths to give me hard information and suggestions on lenses ... but I need to explain more ...
I'm engaged in what can best be described as "photoarchaeology." I have about 6,000 digital images and something less than a couple of hundred analog. Digital is great for finding things but to draw out details I of course need film.
This is my fifth year struggling to document a large number of old monuments I've located along some fairly rough stretches of seaboard. They seem to be covered with as many as thousands of inscriptions and pictographs. If they are not too weathered, I would like to be able to "read" them (that is, if I can ever figure out what alphabets and languages they're written in.)
There aren't that many days of the year when I can shoot. Critical parts of the monuments often descend into the ocean, so I need the lowest possible tide. They are light dependent, so I must shoot at only certain times of the day or there will be nothing visible to photograph. And, oh yes, I'd rather not have my fingers freeze to metal and I need somewhat windless days so the wind doesn't create blur when I fire a shutter. It can't be foggy, raining, sleeting or snowing.
Because there aren't that many good days when all these factors are right, I need to make each shot count.
I'm looking for 100 degrees plus of edge to edge sharpness with as little distortion as possible.
If a lens has a narrower field of view than that, it won't be able to capture what I'm shooting. The monuments are simply too big. Sadly, I'm rarely graced with the option of taking a step or two back.
Movements are less important at the moment (since I only have the Speed) but they will be important when I get a better camera, which I would have probably purchased already if my car hadn't frizzed out on me last month!
Forget that I have a Speed. I'll be moving to something better as soon as possible. But no matter which camera I end up with, I'll still need the best possible lens (or lenses) I can afford which are suitable for fairly rugged field use (not studio size), and which have the edge to edge sharpness, as little distortion as possible, and 100 degree plus field of view that my subjects require.
Dan, Trevor, Ole, you guys are right! It's unwise to risk a costly SS XL on a camera without movements, especially where there's ample opportunity to damage both of them, but I see no way out here. Personally, I'd rather that a $200-300 lens did the trick myself!
What do you guys think? Now that I've given this really windy description of what I'm up against,
are there any other fine lenses I should be looking at that will give me the equivalent to the SS in sharpness and field of view, sans distortion?
Lets not get started on Mamiya MF options yet. I'll probably end up with one of those, too.
I sure appreciate all the help here. The little I know about technical photography I have learned here on apug from all of you.
