mzcloud Posted November 19, 2009 Share #21 Posted November 19, 2009 Advertisement (gone after registration) I have noticed that the 1.4 nokton has focusing shift problems. Other than that, its pretty good. Quote Link to post Share on other sites More sharing options...

jsrockit Posted November 19, 2009 Author Share #25 Posted November 19, 2009 But using it at f/2.8 and slower is a no no because of focus shift IMHO. Huh? even at f/8 and above? Quote Link to post Share on other sites More sharing options...

lct Posted November 19, 2009 Share #28 Posted November 19, 2009 Huh? even at f/8 and above? Looks pretty good at f/8 if you don't shoot against the light but i don't go that slow usually so take what i say with a pinch of salt. Above f/8 i don't know sorry.

jsrockit Posted November 19, 2009 Author Share #29 Posted November 19, 2009 I use the lens and don;t have any issues with it, so that is why I was surprised that someone they only liked to use it wide open... I guess the M8 amplifies the issues with this lens if I understood correctly. I'm concerned because I'm buying an M8 and this voigtlander lens is my only lens (and I like it that way).

farnz Posted November 19, 2009 Share #30 Posted November 19, 2009 It's been noted before that there are variations in the performance of samples of some Voigtlander lenses and particularly the 35/1.4 Nokton. Sean Reid's first review sample was poor, for example, but it sounds like you may have a good one. This is why you're hearing these comments. Pete.

burkey Posted November 22, 2009 Share #31 Posted November 22, 2009 (edited) I've been taking a lot of test images with my new CV 35/1.4 MC with my M8 for the past two days. At first I thought I saw excessive focus shift, then I was sure I had a rangefinder alignment problem. But the latest test images are looking pretty good. Here's a shot I took this morning with the lens at the questionable f2. Focus seems accurate, or at least to me. (Focus was at the front of the glasses frame and bow.) A 6"X9" print was very acceptable. ISO 640, my norrnal work flow with LR 2.5 and CS4. Just thought I'd share it. Flange will be on the way to John Milich for milling tomorrow. . . .

ottocrat Posted November 22, 2009 Share #32 Posted November 22, 2009 (edited) I've also been testing my new 1.4 Nokton MC over the weekend and it looks pretty clear to me that I also have the infamous back focusing problem. Rough and ready test here. Here's a 100% crop at f/2 - I was focusing on the duck, but the rabbit just behind is obviously much sharper. I wonder if I'm within my rights to insist on a refund? In Belgium retailers are usually very reluctant and will insist on sending the faulty product off for repairs for months on end...

Bo_Lorentzen Posted November 22, 2009 Share #33 Posted November 22, 2009 Chris, first - the distance between the duck and the rabbit seems about what my lens wanders.. but when I look at all your samples, it almost look like the rabbit is sharper also in the first image.? "when" that lens wanders, it moves pretty dramatically, and the duck should be perfectly crisp at 1.4 and the rabbit at 2.0 / 2.8 ish. it goes pretty fast. Still there is clearly wandering, and you should be able to say there seem to be a product with the lens, please hand me a good one. in the US a store is liable for selling defect product. .

ottocrat Posted November 23, 2009 Share #34 Posted November 23, 2009 Thanks Bo, I appreciate the advice. I do also wonder whether there might simply be an issue with my manual focusing abilities! Anyway, I'm going to try to return the lens tomorrow and purchase a second hand Summicron instead. Wish me luck... Quote Link to post Share on other sites More sharing options...
Bo_Lorentzen Posted November 23, 2009 Share #35 Posted November 23, 2009 Chris, I own the 35 1.4 and I would swap it in a instant for a clean glass beat up 35 cron.! . Quote Link to post Share on other sites More sharing options...
cfritze Posted November 23, 2009 Share #36 Posted November 23, 2009 ottocrat: have you considered using the focus chart here to test your lens? Instructions on that webpage, uses a tripod. Showed my 40/1.4 to be spot on for focus at 1.4, and shift v little on stopping down. I think with shots like the stuffed animals in your example, a little movement of you with the camera or slop in your focus action could throw you off. In the tests I did I always made sure to start consistently from either infinity or MFD, then focus continuously until target appeared on, then shot. The linked chart above was meant for non-RF cameras, so I added a strong vertical line to the center... Quote Link to post Share on other sites More sharing options...
lct Posted November 23, 2009 Share #37 Posted November 23, 2009 ...Here's a shot I took this morning with the lens at the questionable f2. Focus seems accurate, or at least to me... F/2 is not questionable with mine either. Problems begin at f/2.8. Quote Link to post Share on other sites More sharing options...
Epimetheus Posted November 23, 2009 Share #38 Posted November 23, 2009 Here is quick hand held test shot of the test chart with my Nokton shot with f/2.8 at closest focusing distance. This is a second copy of the lens I have and this one seems to back focus unlike the first one I had. Quote Link to post Share on other sites More sharing options...

ottocrat Posted November 23, 2009 Share #40 Posted November 23, 2009 Chris, I own the 35 1.4 and I would swap it in a instant for a clean glass beat up 35 cron.! . Happily they let me make the exchange, unhappily the beat up 35 cron I bought instead is completely out of whack, it thinks 70cm is 1.2m, so effectively I'm sitting on a credit note waiting for the right lens to come in... On balance though I'm happy not to be stuck with a purchase I regret. Quote Link to post Share on other sites More sharing options...
