Focusing Issues

[Joe Mondello]

OK, I took my R-D1 out for a little night shooting in Times Square last night and noticed a few things on my return, sad to say . . .

1. Back-focusing. I've heard about this on AF cameras but It seems clear that the focus point is behind what I actually focus on -- at least within about 3-5 meters.

2. Infinity. The rangefinder doesn't seem to focus to infinity as the images never align. However, the images themselves look sharp.

I'll probably do a more thorough test over the weekend.

So I guess my questions are these . . . Is this a function of misalignment in the camera or is it a function of the lens?

Since at the moment I only have the 40mm Nokton to try (the 15mm has it's own finder of course) I wasn't sure if this was a lens or camera issue.

OK, I also see the "vertical adjustment" thing is off a tiny bit, probably not a big enough deal to send off for on its own. The actual focusing issues though are another thing altogether.

If I understand you, I believe issue 2 to be fixed with adjustment for Infinity.
As I understand that will also influence on the back focus problem

You can try to adjust it yourself or send it to Epson or DAG

Thanks, Jarle.

I could try to adjust it myself given instructions. Do you know of any for adjusting INF focus? Is it the same set of instructions for the vertical alignment thing?

I sent mine back to Epson for the same Rear Focussing thing, the 28 Ultron was unusable at F5.6 which was funny as I didn`t notice it as much with the 35 F2.5 PC - the loaner focusses all lenses bang on, I`m hoping that they can get aligned as well as the loaner

How much is the DAG alignment?

I'm finding that my refurb R-D1 also needs infnity focus adjustment. Backfocus I can't judge yet,but it also appears to be a problem with some images. Samples form today:

I received the following quote from DAG regarding rangefinder allignment:

"Aaron,

if the R/F is an easy fix the cost is $40.00 plus return shipping, if
the
repair involves additional work to the R/F then the cost would be
$80.00,

regards,

Don
DAG"

Wow that's really reasonable.

Did he quote a turn-around time?

 

[newyorkone]

Yes. That's not bad - at most $80 and shipping. I can probably do it myself but I'd prefer an expert. Thanks for the info.

 

[JeffGreene]

Don tries to turn things around within a week. At least that was my experience, and that was what I was informed by him prior to the adjustment.

I'll ship my R-D1 to DAG first thing Monday morning

Now that I have 3 lenses I'm going to make some tests over the weekend to be more certain that it's not my error, but an actual fault in the camera.
