That said, while I really, really do like the Minolta CLE (and am still absolutely leaning towards it), I do worry about it turning into a brick as it's literally over 40 years old. Perhaps someone can just put my mind to rest on this one. I've even already picked out the two lenses for it!: Voigtlander Nokton 40mm f/1.2 Aspherical and the Voigtlander 28mm f/2.0 Ultron Vintage Aspherical. How do you think these lenses fare as compared to the original Minolta lenses specifically made for the CLE?
I've also heard that the Hexar RF can have rangefinder alignment issues and can turn into a brick too, but considering that it's not that old (respectively), it seems like a contender. People seem to love it or hate it. I do, admittedly, still like the Voigtlander Bessa R4A/R4M (even if other people think it's ugly) particularly since it's newer, being made in 2006. For either the Hexar RF or the Voigtlander Bessa R4A/R4M (or even the Zeiss Ikon ZM, if I can spring for it), I'd get the Voigtlander 28mm f/2.0 Ultron Vintage Aspherical, the Voigtlander APO-LANTHAR 35mm f/2.0, and the Voigtlander APO-LANTHAR 50mm f/2.0.
So, that all said, I'm about to pull the gun on one of these - either the Minolta CLE or the Voigtlander Bessa R4A/R4M. If anyone thinks I'm crazy to put any of my money into these, I'll get the Hexar RF as it's not insanely expensive.
It's late/early and I can't sleep, so here's much more than you surely bargained for...
Bear in mind that photography forums are full of doom and gloom when it comes to pretty much every camera made. There are a lot of people online simply parroting that which they have read elsewhere and you have to be able to read between the lines in many cases. That aside, none of these cameras are getting any younger. I put quite a bit of thought into the possibility of the CLE turning into a brick before I bought mine. In the end I decided that I just had to accept the fact that the camera is going to fail at some point in time and there was simply no way of knowing when this might happen. I feel like I would be doing you a disservice to try to convince you otherwise. (I figure that the same could be said of me.)
As previously mentioned, I use the CLE in conjunction with my M6. Though I do the one camera + one lens thing around town, I typically pack both cameras and two lenses each in a single small messenger bag. With this arrangement, should either camera fail I have a backup. No doubt this tends to impact my take on things as I don't have to rely on the CLE as my only camera. To get a better feel for the reliability of the CLE, my suggestion would be to contact Scott Nielsen in Oakdale, CA to get his feedback (
http://scottnielsenphoto.com). Scott is the Minolta technician that I mentioned earlier who recently came highly recommended by another fellow CLE owner. For all I know, he might tell you to avoid this camera based on his experiences.
As far as the Voigtlander cameras that you mentioned go, the R4M with its mechanical shutter would seem like the more logical choice if you are concerned about cameras turning into bricks. While the CLE is a well regarded camera, I was primarily drawn to it as I'm a bit of aMinolta fan (the XD11 was my dream camera in my youth and I shot with mine for more than two decades). I have no regrets about purchasing the CLE and given my experience with this camera thus far I would do so again. Shooting in automatic mode I have found the metering system to work wonderfully. But with all that said, it is hard for to me to argue against an all-mechanical camera given the sort of concerns that you have.
I don't have any experience with the Voigtlander lenses you've asked about, but I would guess that that there are others here who do. Again, I bought the M-Rokkor lenses because as a Minolta fan I liked the historical tie-in and they are still generally well regarded. However, I would expect the newer Voigtlander lenses to outperform the Minolta lenses. Regardless of the lens specifics, I can say that I enjoy the simplicity of the 28mm and 40mm combination offered by the CLE. Still, if you don't mind carrying three lenses it seems hard to go wrong with the 28mm, 35mm, 50mm combination you are considering when it comes to the R4M.
As far as my results with the CLE go, I would refer you to
this thread on another forum. I feel like shooting in aperture-priority mode with the CLE tends to result in good exposures the majority of the time. But if you prefer to be able to set both your aperture and shutter speed on your own while referencing the built-in light meter, then I would actually have a hard time recommending the CLE as this would require you to switch back and forth between aperture-priority mode and manual mode in order to make use of the light meter. As I mentioned before, for whatever reason this was common practice among rangefinder cameras back in the 70's when the CLE was developed.
Sadly, I'm just not as competent as many other photographers. While I do sometimes work on using the Sunny 16 rule, I remain pretty reliant on using the built-in metering of my cameras. I do feel that my images have benefited somewhat from the CLE given how good its metering system works in aperture-priority mode. But in all honesty I do wish that the meter worked in manual mode as well.
Sorry, I don't mean to make your choice harder, but so often people only tend to encourage others to buy the gear they themselves own. While I really like my CLE, I obviously had my own reasons for buying this camera that likely wouldn't apply to most people. On the surface the R4M looks like a good choice provided the general opinion is that this is a well built, reliable camera. It doesn't benefit me at all if you were to end up buying the same camera that I own. Knowing that there is no such thing as the perfect camera, I simply hope you find the right camera for you given your needs and preferences. Again, good luck to you.
