This is weird.<br /><br />50/1.5 Nokton on, no problem.<br /><br />75 Heliar on...won&#039;t focus at infinity (patch doesn&#039;t line up)<br /><br />50/1.5 Nokton on again...won&#039;t focus at infinity...then after one full turn of the focusing ring, it lines up fine.<br /><br />both lenses work fine on my R2. This is only hapenning with my R2a.<br /><br />rf need calibrating?&nbsp; ???

Is the rangefinder cam wobbly-loose, or otherwise buggered up?&nbsp; You can compare the two cameras, I&#039;d guess that the parts are similar.<br /><br />If it&#039;s something internal that has come undone, it&#039;ll need repair attention, unless you can do that sort of thing yourself.<br /><br />Unfortunately from what I read on the internet, Voigtlander new products do sometimes tend to come apart.&nbsp; Usually they can be put back together.&nbsp; <br /><br />Good luck, and let us know how it&#039;s going.

Don&#039;t know if this qualifies as weird behavior or just shoddy workmanship,&nbsp; but my R2a has been subject to occasional jams -- you would press the shutter release and nothing happened.&nbsp; At first I thought it was a dead battery but other owners reported this behavior on various forums as well.&nbsp; They said it was a defect in the advance mechanism and that if you advanced the film too quickly after making an exposure the shutter would not cock.&nbsp; Applying some pressure to the advance lever would sometimes solve the problem.&nbsp; Well, beware.&nbsp; Yesterday, my R2a kept jamming and I kept missing shots and I put some pressure on the advance lever and the internal gears must have sheared.&nbsp; The lever now moves freely back and forth but that&#039;s all it does.&nbsp; No film advance, no nothin&#039;.&nbsp; I&#039;m posting this as a heads-up to other owners that the advance mechanism is apparently extremely fragile and to be careful about trying to force it.&nbsp; The R2A does make an attractive doorstop, however.&nbsp;

This happened to my R2a once in the couple of years that I&#039;ve had it. Took it to a local repair guy and it&#039;s been fine since. It&#039;s never happened to my R2. I abuse the heck out of both of them (they are both proudly scarred and dented) and honestly I haven&#039;t found them to be less or more &quot;reliable&quot; then the SLR stuff I&#039;ve used in the same price range with the only exception being the Nikon FM2n and FM3a.

I had somewhat of a similar experience with my Ultron and it turned out to be the CV LTM-M adapter. The Ultron would focus past infinity on my Bessa-T. I changed the adapter for another one and it fixed the problem.

I&#039;m starting to think I need an adjustment, but I&#039;ll try that first. I have another adapter stuck in my R2 that I can try in the R2a and see if that makes a difference.<br /><br />Thanks&nbsp;
