P

picturetaker

I got again a roll of film were 30% of the pictures are crap. Many pictures i took are aut of focus, most are focus behind the subject.
So what shoul i doo ?
I did send the Camera G1 and 90mm lens to the Customer service wehre the fixt the problem.
Now the fcocus problem is here again.
I cant see any low battery warning.
I did get the focus confirmation.
what should i do to get fuking reliable focus with the G1 and 35mm,90mm lenses. Are there any idias to solve the problem without sending the G1 and lenses to Contax ?
Thank you for your help.

I'll tell you what I found out a lot of G2 useres forget about...........If the focusing mark is not exactly on the subject, the picture comes out lousy.

I could confirm this ; the G2 focus is very accurate if you pay attention to what you are focussing to !! this is not like a "smart" multi-zone AF system.
I assume that you have the same problem with your G1.

I have recently read that there is a "problem with the 90mm lens focusing on the G1. I have used mine for over a year with no problems. Am I just lucky or is this a problem that can appear at any time?

thanks,
Tom

I just had this problem for the first time with my G2, although it was not only the 90mm lens, it was the 45mm and 28mm as well. The camera apparently didn't focus on anything sharply. At the time I was shooting, I did experience the camera "hunting" for focus with the shutter not firing for a second or two, then operating as though focus had been achieved. What's especially frustrating is that the problem was intermittent. I'm getting ready to send everything to Contax in New Jersey USA, along with s&le slides. Has anyone experienced the problem the way I have? Was there a fix? Also, those of you who have had G2's serviced in New Jersey, were you satisified?

Many thanks.

Rob:

Although I have not had that problem, if I did I would check to see if there was any difference if focus settings; caf, saf, and manual. I would check to make sure all of the focus windows on the front of the camera are clean. I would also try some fresh batteries. Also, I would consider under what lighting conditions did these exposures occur? Similar gray area, difficult situations to focus, slow speed exposures, unsteady, etc.

Are the rangefinder glass covers on the front top of the camera dirty? I find mine get a lot of fingerprints on them...and it's a good idea to keep them clean.

BTW, you might want to check manual focus, and see if that works (like on infinity, and take some pictures of stuff far away that will be obvious if they are in corrct focus or not).

Regards,

Austin

> Rob, I had a focus problem that developed in a used G2 I bought. It was fine when I got it, but then started acting up. It would fail to lock focus, it would hunt, and sometimes the motor would just grind away with nothing happening. I sent it to Contax NJ, and they replaced the autofocus motor inside the camera, among some other minor things. It took about two weeks for them to give me a quote for the repair, and then another two weeks before I received it back. The repair cost $120, and since then everything has been perfect. Originally, I was given an estimate of 4 weeks total, and they met this, and fixed the problem. So I would say I recommend them, based on this one experience.

Best fix for G2 autofocus problem - get a Leica SLR manual focus camera. - Doug

Good point, then you know you have to have your rangefinder adjusted.

Doug, u may indeed have a point, but it certainly doesn't have to be Leica stuff. Come to think of it, one of my better friend has an R8 with a 28 and 90mm. We were both shooting Optima 400 and both processed at my lab. His stuff showed remarkably less "zippydydooda" than the Distagon and Planar. Kinda flat actually. I think I'll keep beating the crap out of my old 137's then haul out the G2 when I want to transcend.

Other than that, I don't have a lot of experience with Leica images. Strange thing is that a lot of my customers actually own a Leica rangefinder but none of them ever give them a work out. Never could figure that one out, because I sure would if I had such a thing.

Rob,

Try using a bit more force when mounting the lenses to the camera and listen for the click that indicates they are fully mounted. I ruined several roles of film by not doing that.

Thanks to Gilbert, Austin, and Neil for your helpful replies. In taking a closer look at my slides, I'm relieved (!) to report that all the out-of-focus shots were taken with my 90mm lens, despite what I wrote earlier. My apologies for the inaccuracy. I'll take a look a the threads related specifically to the problems with that lens.

And thank you, too, Bill from Pittsburgh. Your suggestion that the lens might not have been fully mounted is an intriguing one. Would you mind describing what your images looked like that you say were ruined?

OK, I haven't done an exhaustive analysis, but my hunch is that some combination of user error or inattention and poor maintenance was the cause for the focusing problems I experienced. User error: I remember I did have some difficulty mounting the 90mm lens at the time some of the out-of-focus shots were taken. Inattention: At times in removing the G2 from my camera bag I discover that one or another of the control dials or switches has been moved out of position. I don't remember it happening this time, but it may have. Maintenance: A deposit of filmy grime has built up on the mounting rings of my lenses and the camera. It's possible the grime interfered with the electronic contacts of the lens or camera, or h&ered the travel of the mechanical pins on the mount. So, thanks again for the helpful replies. Before I go to the time and expense of having the camera and lens serviced, I'll clean everything, make sure of my settings, and shoot some test film.
