sean_reid Posted October 2, 2006 Share #41 Posted October 2, 2006 Advertisement (gone after registration) Let's change the focus a bit to the longer end. The natural successor to the classic 90 mm lenses is of course the 75 mm focal length. Does anyone know how good the C/V 75 mm is? Is it usable wide open? Of course we all lust for the 75 mm Summicron, but there's that financial aspect ... BTW I agree that the 15 mm is better than the 21 mm, especially in the corners. Quite remarkable definition. This will go into my M8 kit with my 28 Summicron. The current 50 mm Summilux is a fabulous lens (like the 28) but will be useful largely as an indoor 'people lens'. The old badger from the days of flashpowder I don't know the answer to this but I will be testing the 75s on the M8. Cheers, Sean Link to post Share on other sites More sharing options...

The old badger from the days of flashpowder Hi Lars, The CV 75/2.5 is one that I am interested in, too. Popular Photography tested it in their July 2000 issue and it was very good even wide open. I did see some samples on RFF-Leica M forum. Bob Link to post Share on other sites More sharing options...
jlancasterd Posted October 4, 2006 Author Share #43 Posted October 4, 2006 I can't get into detail with this but some lenses may actually perform better in the corners on the M8 than they do on the R-D1. That may sound counter-intuitive but sensor size is only one of many variables in the equation. I'll be testing the various 28s on the M8 for an article but obviously that won't be out right away. For someone who wants to get a 28 right now, there is the option of just buying a 28/1.9 and trying it on the M8. If he or she is not happy, sell the lens. It's fairly inexpensive and should hold it's value pretty well. My favorite lenses from CV are: 28/1.9 Ultron 35/2.5 Pancake II 50/1.5 Nokton I have a hunch that all three will do very well on the M8 but I can't say anything definitive until I've done the comparative testing. I own all three. How does the 28 Ultron do wide open? I shoot that lens wide open for assignments all the time on the R-D1 and it's great. I love it. Naturally, it will also be interesting to see how the CV 12 and 15 do on the M8. On the R-D1, the 12 vignettes far less than the 15. Cheers, Sean Sean Can you give us a 'Heads Up' on this forum when you test any of these with the M8 on your website? I've already bought a near-mint CV Nocton 50/1.5 on the strength of your test of it vs Leica and Zeiss equivalents and am keeping a look out for the CV 15mm, 28/1.9 and 35mm 1.7 or 1.2. I suppose I should also order an M8... (silver chrome, of course... my first Leica was a 1960 silver chrome M2 with a Summarit 50/1.5) :D Link to post Share on other sites More sharing options...
sean_reid Posted October 4, 2006 Share #44 Posted October 4, 2006 Hi John, I won't announce new lens tests here because there are a couple of forum members who get very upset if I announce a new article on the forum. But, generally, when something relevant to Leica is written on my site, someone brings it up here for discussion soon afterwards. I think you're going to do well with the 50/1.5 and 28/1.9 on the M8 (hunch which precedes actual tests). I have trouble warming up to the CV 35/1.7 even though I own one. I like the Leica 35/1.4 Asph much better than either of the fast CV 35s. The CV 35 that I like a lot, though, is the 35/2.5 Pancake II which I also own and use frequently. That tiny lens is a real sweetheart <G> There's also, of course, the Zeiss 35/2.0 which has it's own look but is a wonderful lens. Finally, it goes without saying that the Leica 35/2.0 is excellent as well. If one can afford it, I think a lot of people will like the Leica 24/2.8 on this camera.

Bob Hi Lars and Bob: Over on Erwin Puts' site he reviews the CV 75mm lens, along with other CV, Zeiss ZM, and Leica M and R lenses. You may want to see what he has to say about the CV 75 (generally good, especially factoring in the low price). Dave G in NJ Home Link to post Share on other sites More sharing options...
basharing Posted October 5, 2006 Share #46 Posted October 5, 2006 One issue with Voigtlander lenses might be that they do not have the "black and white recognition dots". I.e. the camera doesn't know what lens is being used. It seems that this information is useful to compensate for vignetting. Hence I suspect that Leica lenses enable correct compensation for vignetting, while Voigtlanders don't. But then, if you should raw you don't apply in-camera compensation for vignetting at all.

sean_reid Posted October 5, 2006 Share #47 Posted October 5, 2006 Advertisement (gone after registration) That's true but you may discover that many lenses on the M8 don't need any vignetting compensation. Cheers, Sean Link to post Share on other sites More sharing options...
humanized_form Posted October 5, 2006 Share #48 Posted October 5, 2006 something i'm not clear about: do the 6 bit codes have any function when using the new flash features on the M8? kevin Link to post Share on other sites More sharing options...

Cheers, Sean Which is a good thing, as that means the offset microlensing is getting enough light to the periferal pixels to mitigate the need to boast light values thru software. Which in turn means we can avoid noisey corners. I personally avoid using ant-vignetting software whenever possible because of the noisey corner issue Rex Link to post Share on other sites More sharing options...
Guest guy_mancuso Posted October 5, 2006 Share #50 Posted October 5, 2006 something i'm not clear about: do the 6 bit codes have any function when using the new flash features on the M8? kevin Yes Kevin they do,. Sean may correct me here but you will be able to use TTL now with the M8 and the coding will also zoom the flash for like the Metz 54. The DMR does not have the TTL function but the Rom will zoom the flash. So if flash is important than you can do what i did either have coded lens or have them coded in the flash zone lenses. For me the 28,35 and 50 i made sure I have the Rom on the DMR because those are my most used lenses for using flash for events. Now having said all that is TTL better than just using A mode on the flash ? Yes , No and maybe depends on the scene. I do very well on A mode and don't really miss TTL coming from my Canon and Nikon days. Link to post Share on other sites More sharing options...

The angle response curve is very different from the one for the KAF-10010 (that I posted on RFF). The saturation signal is also up 50% to 60k electrons. Less vignetting and more data to push around to correct when needed. Bob Link to post Share on other sites More sharing options...

steve_l Posted October 7, 2006 Share #57 Posted October 7, 2006 Sean (and others) Thanks for all your recommendations in this thread...especially for lenses that have that creamy B&W flavor. What about on the "wider than 28 but not super-wide" end I mean 19mm-25mm (25-33 on the M8), for B&W, where resolution and corner performance are important, but contrast can be lower and be actually better that way? Sean's reviews seem to be a bit down on the CV 21 and 25, but it is hard to tell exactly whether he is just describing their characteristics (e.g., vignetting) and still likes them anyway for B&W...or not (or maybe that they just don't measure up to his favorite, the 28 Ultron). And what about the Canon 19 and 25? More expensive than CV, but available... I am curious to try some of these lenses, based on Sean's descriptions - I shoot B&W, spent 30 years mostly with a pre-ASPH 35 1.4....made the switch to digital and Leica ASPH at the same time, maybe it is time to back up a little on the lens side.

Hi Steve, The 21 and 25 both vignette significantly on the R-D1. I'll test the CV 21 on the M8 with the Leica and Zeiss. I don't think it will match up well but I'll keep an open mind. The CV 25 has no RF coupling which makes it almost impossible to test properly against the Zeiss 25 and Leica 24. As such, I don't plan to test it. In addition to the 28/1.9, the CV 50/1.5 is another standout CV lens. A test of that lens against the Zeiss 50/2.0 and Leica 50/2.0 (all on the R-D1) is up on the site now.

Bob Ross Posted October 7, 2006 Share #59 Posted October 7, 2006 Bob without looking and going by your comment sounds to me like more Dynamic range. Bring it on , I say Hi Guy, The specs show the linear DR for your DMR at 67 dB and for the M8 at 71.5 dB, so yes we'll get some extra f/stops. I think the DR on my Oly E-1 is the same as your DMR, though it does have an AA filter. The E-1's sensor is one half the size of the DMR's and one generation earlier. It needs different sharpening techniques and wont enlarge as far, but we are seeing similar image qualities. Bob Link to post Share on other sites More sharing options...
burkey Posted October 7, 2006 Share #60 Posted October 7, 2006 I certainly can vouch for the CV 75mm lens. It's definitely "top shelf". I use one on my Bessa bodies for film work often. A quick check over on RFF will find many fans for this lens. As an M8 is a bit in the future for me, I remain very interested in hearing about Voigtlander lenses on the new digital "M".
