I was just as excited when my iif was returned from a CLA. It's indeed a wonderful thing to have a 70+ year old all mechanical camera, functioning like a new one. Nothing like it, but then there's nothing like a Leica LTM...
Mine was from a deceased estate. I paid a fair but not exactly cheap price for it. Bought new by its original owner, not greatly used, and left to gather dust in its never-ready case for 20 years before it fell into my hot little hands. So in that sense, a great find and a bargain, most definitely.
I initially thought mine was a iig, but as it turned out it's a iif which at some time was returned to Leitz to sort of upgrade it. Probably a repair or a CLA at the time, but I did wonder why it wasn't upgraded at that time to a iii.
Finding all this out took me a while and quite a lot of time researching on web sites and in books. Odd I reckon that Leitz, usually so accurate and precise with its data and user information, could be vague on its later model LTM cameras. Other owners have told me they had the same situation in looking up info on theirs.
Over time I've picked up a fair number of useful accessories. One super good find was an early version collapsible Summicron 50/2.0 with caps, a fitted lens hood and filters, kindly given to me by an elderly neighbour who'd had it in a box in his garage for many years. There was a lot of haze in it and I had to get it dismantled and cleaned, which cost me a little more than I paid for the iif. But the 'look' of that lens has made the $$ I put into it, well worth it.
Given my poor eyesight, a decided to (wisely as it turned out) invest a little extra $$ in a Leitz turret viewfinder. Which makes all the difference in using the camera.
Loading film can be a PITA. It took me a while to fine-tune the film trimming to get it safely into the camera without losing too many exposures. It can be done, and if an all-thumbs person like me can figure out a way, then it's easy.
I now have a 35/3.5 Summaron and the legendary 90/4.0 Elmar, both circa 1960 lenses. So newer than the camera. Someone has offered me a 135/4.0 for a good price, but I reckon the LTMs aren't the best camera to use for those long lenses, so I may pass on it. Or knowing me, I'll buy it as a collectable, it's a 1950 lens.
In this digs-everything era I don't use my film cameras as much as I should. The cost of film (here in Australia) is the main reason for this. I use the iif a little more than my once-beloved Contax G1 kit, which has by far the best lenses, in my opinion better than any Leitz glass I've used. Subjective, of course, and entirely my opinion. Also maybe comparing apples to oranges.
