k-hawinkler Posted February 25, 2011 Share #1 Posted February 25, 2011 Advertisement (gone after registration) I am using a number of M-lens heads and V-Telyts on my Nikons without problems and would like to add some R-lenses. Now I read about focus problems with the 50 R-Summilux on a D3X or SD14 http://www.l-camera-forum.com/leica-forum/architektur/168939-ganz-schoen-aufgeloest.html, posts #13 and #14. Do folks here have similar experiences? Thanks, K-H. Link to post Share on other sites More sharing options...

integrale Posted February 25, 2011 Share #2 Posted February 25, 2011 Hi K-H I don't have a D3 but a D700 and several R-lenses. I agree that you cannot rely 100 % on the focus confirmation in the D700; this "issue" is most apparent when using super-fast lenses, especially longer ones, since at least the D700 indicates in-focus over a small area, and if you have a DoF of just a few centimeters, you'll need some practice to nail focus consistently. Check out the Nikon & Leica thread on NikonCafe.com; there's a guy there (shtarka1) shooting FANTASTIC shots with a D700 and Summilux R 80; he seems to get it right... (I believe the focus system on a D3 is somewhat different from the D700, how, I do not know). Link to post Share on other sites More sharing options...
k-hawinkler Posted February 25, 2011 Author Share #3 Posted February 25, 2011 Hi Jakob, Many thanks for the feedback. Impressive shots at NikonCafe. I use my Leica lenses on M9 and D3, occasionally also on D300. I have not noticed any front- or back-focus yet for M-lens heads or V-Telyts. The D3X is interesting as it has 24MP compared to 18MP for M9 and about 12MP for D3. The fastest Leica lens I have for use on the D3 is a Summicron 90/2. So what super-fast R-lens is worst? Best, K-H. Link to post Share on other sites More sharing options...
lct Posted February 25, 2011 Share #4 Posted February 25, 2011 Front- or back-focus should not be a problem with dSLRs imho. What you need is perhaps a good focusing screen? Link to post Share on other sites More sharing options...
Nicoleica Posted February 25, 2011 Share #5 Posted February 25, 2011 Front- or back-focus should not be a problem with dSLRs imho.What you need is perhaps a good focusing screen? I find that I can focus manually perfectly well with standard screen on my D3s. I use quite a few old (from the 60's and 70's) manual focus lenses on it.

lct Posted February 25, 2011 Share #7 Posted February 25, 2011 Advertisement (gone after registration) But it is on the list Brightscreen styles of screens hence my question. Link to post Share on other sites More sharing options...
k-hawinkler Posted February 25, 2011 Author Share #8 Posted February 25, 2011 Correct, IIRC there were some discussions about Brightscreens and their disadvantages. I don't remember the details, but never tried one. What's your experience with them? Thanks, K-H. Link to post Share on other sites More sharing options...

menos I M6 Posted February 26, 2011 Share #12 Posted February 26, 2011 I am too veeeery interested in any experience with the brightscreen and Nikon D3. I have a Noct-Nikkor, which is very difficult, to focus @ f1.2 with the D3 without focus bracketing. I love the H-2 full matte screen in my Nikon F3HP though, which makes focussing the Noct very straight forward. Interesting looks for me therefor the #1 version full matte screen: Nikon D3/ S / D3X: "b771" Anyone has tried this screen? Link to post Share on other sites More sharing options...
andybarton Posted February 26, 2011 Share #13 Posted February 26, 2011 Strictly speaking, the screen on a D700 isn't user changeable. Fiddling around with little bits of wire in the throat of the camera isn't something I will be doing with mine. Link to post Share on other sites More sharing options...
farnz Posted February 26, 2011 Share #14 Posted February 26, 2011 K-H, I use an 80 Summilux on my Sigma SD14 with manual focus and no focus confirmation and I haven't noticed a problem. Pete. Link to post Share on other sites More sharing options...
tobey bilek Posted February 26, 2011 Share #15 Posted February 26, 2011 One of the reasons I use my D700, Katz Eye. Unfortunately I have had to adjust screen height with both 200 & 700 to eliminate slight front or back focus. It is not a simple screen swap. Good news is the screen height is adjustable with 1.5 mm hex and the screw bottom RH corner or mirror box as viewed from front on the pro cameras only. Others need reshiming. Use a fast lens and a aluminum yard stick at 45 deg as a target. $3 at home depot. This gets visual focus to match AF, ie green dot. Af is in the camera bottom, Visual is in the top. Do not touch the primary and secondary mirror rests or you will get the AF out and pic will not be what you see. These are computer set and you do not have a prayer of getting them back correctly. We really need a split made for 1.4 and not 5.6 for the increased accuracy. Downside is the splits go dark after 2.8. As this is not a field change operation, Katz went conservative like the Nikon A screen. They do not and have no current intention of making a D3 screen as their "mold" can barely make the D700 size. Major investment with little upside for them. Nikon wants you to use the AF lenses. You might consider an F6 screen and cutting to fit or other third party screen like focus screen.com. Set up a 700 correctly and you can use MF fast glass. Link to post Share on other sites More sharing options...
lct Posted February 26, 2011 Share #16 Posted February 26, 2011 ..."b771" Anyone has tried this screen? No sorry only #2 (microprism spot center) and # 5 (large split image with large microprism collar). Link to post Share on other sites More sharing options...
k-hawinkler Posted February 26, 2011 Author Share #17 Posted February 26, 2011 Thanks to all for the very interesting feedback. For purposes of discussion I would like to separate the question of focus screen replacement from the question of focus screen adjustment. As indicated in the feedback, a very fast lens would tax the focus adjustment for the green dot and LV focusing and of course the skills of the photographer. As I am not a trained Leica or Nikon technician and don't plan to work on either camera myself, I simply would like to pose the question to what degree the factory or qualified technician typically can adjust the focus on a Nikon camera. Simply putting a Nikon mount on an R-lens - even a very fast one - should not create the problem in the first place. Please, correct me where I am wrong. Thanks. Best, K-H.
