Hello,
Is no one going to suggest the M Rokkor 28mm, f/2.8 that this camera was designed to be used with?
The Rokkor 28mm is an awesome lens - I would put it up and over anything Cosina has put out. Many say, "It's just a Minolta," but that's the snobbery in us coming out. Your camera, the Leica / Minolta CL and the lenses for each were designed in conjuntion with Leica and are phenonemal pieces of gear (don't take my word for it, read it on Gandys site:
www.cameraquest.com)
Just make sure you get a Rokkor 28mm that has been "re-engineered" by Minolta. The original design / coating produced tiny white spots on the lens after a few years. Minolta had everyone send their lenses in to be recoated, but a few out there on the used market never made their way back to the dealerships. The spots don't effect the image of the lens (I'm told - mine has been re-done), but it's better safe than sorry.
Your CLE, which is probably my favorite RF after the M5, is perfect for this - or any other 28mm lens.
Also, be sure to take advantage of the magnificent TTL flash technology on your camera. Forget the so-hard-to-find-it's-rare little bitty flash Minolta sold with the CLE, it's big brother the 360PX is amazing on the camera. With TTL flash, bounce, swivel and a seriously high GN (I forget it at the moment, but you can use the 360PX to shoot night sports) all for the cost of going to the movies (these flashes once sold for BIG bucks, back when the dollar was worth something). When I use mine for flash, I typically mount it on the Minolta PG-II flash bracket, which allows for additional power (no changing batteries during an event) and an elevated off-to-the-side illumination.
Welcome to Minolta RF! You're going to love it.
BTW, make sure you know the cameras restrictions. There are a few Leicas that will not work with the CLE, including one of my favorites, the Summicron DR 50mm, f/2. I'm told it can do some ugly stuff to the inner workings if you put this or a few others on it, so beware. I think Stephen Gandy's site has the compatability list on it - or just Google it.
Good luck and let us know which lens you pick!
