Guest guy_mancuso Posted January 24, 2007 Share #22 Â Posted January 24, 2007 Here is the one for the Leica 21mm that i bought Voigtlander Metal Brightline Viewfinder for 28mm - Black Link to post Share on other sites More sharing options...
cme4brain Posted January 24, 2007 Share #23  Posted January 24, 2007 Does the magnifier come with the M8 or is it an extra? If an extra, how much? John  You can buy an equally good magnifier off of ebay for $60- I bought mine that way. Try here for an ebay store:  eBay: 1.25x Viewfinder Magnifier for Leica M6/M7/MP/M8 (item 200069375846 end time Jan-26-07 05:57:31 PST) Link to post Share on other sites More sharing options...

Adorama, Cameraquest and Photo Village do sell the Voightlander gear  Hi Guy,  Yes, the 21D was designed work with the Epson R-D1 and it shows roughly a 32 mm EFOV which is just the ticket for a 24/25 on the M8. Since finder frame lines tend to run tight, the 25s actually match both the M8s internal framelines and the 21D's frame lines better than a 24 would.  Cheers,  Sean Link to post Share on other sites More sharing options...

Adorama, Cameraquest and Photo Village do sell the Voightlander gear  Although expensive, the Leica 21-24-28 external viewfinder is great. On the M8 this gives you a full view using WATE at 16mm, 18mm 21mm and covers the 21 elmarit as well. I have gotten to the point of just leaving it on the M8. I have also been using my 15 R elmar and the novoflex R to M adapter and the 21 position on the viewfinder works really well. (and looks a lot better than the viewfinder for the tri-elmar.  Woody Spedden Link to post Share on other sites More sharing options...
Guest Bernd Banken Posted January 24, 2007 Share #28 Â Posted January 24, 2007 at the moment I'm not wuite sure wheter this focus testchart is useful for RF cameras. The difference of distance between the RF window to the chart and the lens distance to the chart are not so small, or? Who knows otherwise you are running into a dead end street... Â Cheers Bernd Link to post Share on other sites More sharing options...
Guest guy_mancuso Posted January 24, 2007 Share #29 Â Posted January 24, 2007 I did this test two ways with the center line and also just did it on the text in the middle to double check myself. It does seem like a SLR test becuase it is hard to get the focus the way they set it up. Link to post Share on other sites More sharing options...
Guest guy_mancuso Posted January 24, 2007 Share #30 Â Posted January 24, 2007 Another way to test this like the way they did it is sort of like a eye chart. On a sheet of paper in word make like 6 sentences of type and double space them apart, use big bold type than focus on one line which would be easier for RF camera's and than you know you have equal distance between sentences. Just a idea that may work better Link to post Share on other sites More sharing options...
pemayeux Posted January 24, 2007 Share #31 Â Posted January 24, 2007 I used the charts on my M8 and found that my 50 lux ASPH is the culprit, backfocussing by 8mm and the 75 lux backfocussing 6mm. My 35 is right on the money, the M8 spot on. I ran the test for 3 hours, tripod mounted using the downloaded sheets. I could then verify that I had perfectly focused during the test by simply changing focus using the depth of field scale as a point of reference. The 50 lux had to be focused closer by 1 stop and the 75 by 1/2 stop. Link to post Share on other sites More sharing options...
wattsy Posted January 24, 2007 Share #32 Â Posted January 24, 2007 When doing these tests I recommend doing them both wide-open and stopped down to F2.8 or F4. You may be surprised by how much focus shift there is between apertures. I can see it with both my 35/1.4 ASPH and 50 ASPH. The shift is enough that the results at F1.4 can appear sharper (at the point I am focussing on) than at F2.8. Link to post Share on other sites More sharing options...
glenerrolrd Posted January 25, 2007 Share #33  Posted January 25, 2007 Roger, I'm not Guy but, as I discussed in my review of 24/25 lenses on the M8, a great external finder for the 24/25s is the Voigtlander 21D. It allows one to see the full frame without the lens intruding into the frame line area. Thanks Sean...I must have missed that because I read the article...seems like they are sold out at Cameraquest..know anybody else that might stock them...scanning all the usual suspects now Thanks Link to post Share on other sites More sharing options...
cme4brain Posted January 25, 2007 Share #34  Posted January 25, 2007 lloyd- is the hk model also threaded to allow further mounting of leica diopter? thank you. john  Sorry for the delay in getting back to you- I am doing out of town medical consulting and am away from my Leica. I am not sure if the HK viewfinder magnifier is threaded for an additional diopter eyepiece, but I think it is. I will check when I am back at my home.

gesper Posted January 25, 2007 Share #35 Â Posted January 25, 2007 Yes, the HK Supplies magnifier has threads as well as a small leather case that attaches to the strap. I am very happy with the quality, as well as the speed and service of HK Supplies. It got here (Chicago) faster than a lot of stuff I have bought from Amazon. I assume it would be fast to Europe, etc. as well. They have a pristine rating on eBay. Link to post Share on other sites More sharing options...
robsteve Posted January 25, 2007 Share #36  Posted January 25, 2007 lloyd- is the hk model also threaded to allow further mounting of leica diopter? thank you. john  No, it is not threaded on the eye side. It will not take additional diopters. To do this, you will need the Leica version. Link to post Share on other sites More sharing options...
gesper Posted January 25, 2007 Share #37 Â Posted January 25, 2007 I'll look again when I go home tonight, but I thought mine had threads. Link to post Share on other sites More sharing options...

cnguyen Posted January 25, 2007 Share #39 Â Posted January 25, 2007 on back focus issue - It's very easy to do it if you have f1.4 lenses. For close distance if you focus and recompose you will get that back focus problem since the depth of field is so small. Focus and recompose is fine for long subject to camera distance but not for short one. There was somebody put up a good article about "focus and recompose" issue with DSLR but I can't remember where.
