It's time to add a wide to my 501CM. I have an 80, I have a 250, I just need something wide. I think a 50 would be a nice addition, as the 40 looks too bulky and probably too wide for everyday use (I'll use it for street and travel), plus I can see me buying a SWCM or XPan in 18-24 months for ultra-wide purposes. What are the differences between the various 50 models? I have found that I can get either of (all in excellent condition): 1. CT* for £250-300 2. CF for £400-500 (which I've read is a CT* with the CF style body...?) 3. CF FLE for £600-700 (which I've read is a big improvement) 4. CFi FLE for £900-1000 (which I've read is an even better lens) My main concern with the CF/CFi FLE lenses is that knowing me, I'll probably end up never setting the FLE ring to what it should be. Is that going to affect the performance negatively? I mean, if a FLE is a big improvement only if the FLE ring is used and ends up actually being worse than a CT/CF if the FLE ring is not adjusted properly, not much point in it! The other thing is, given the prices above, I'm tempted to skip the CF versions. The plain CF is more money vs the CT* for no improvement (if my assumptions are correct) whereas if I'm paying CF FLE money I might as well go for a CFi and have added peace of mind (for the newer lens) and the modern body/controls. So it kind of looks like CT* vs CFi. Not a usual comparison perhaps. The CFi is still within budget but £300 vs £900 is a lot of film and processing. In fact, it is a weekend on the Eurostar to Paris, which is probably better use of the money...hmmmm. I guess what I'm trying to say is, is the CT* so much worse than the CFi for street/travel use, where corner sharpness may not be the most important aspect of my photos? Anyway, thanks for any help!
