carstenw Posted July 8, 2007 Share #21 Posted July 8, 2007 Advertisement (gone after registration) On the bright side of things, we are dealing with a conscientious company, and they do desire to stay at the top, where we want them, so when they find solutions and implement them, I guess we will be some of the happiest camera users in the world, if we weren't already.

Jamie Roberts Posted July 8, 2007 Share #23 Posted July 8, 2007 Carsten - I am prepared to be patient, but for €440, I expect the lens to come back better not worse. Fortunately I have a well functioning 35 cron and so I am not totally disadvantaged. Also, it's not my livelihood. Wilson's point is valid, however, in that current turnaround time and a delinquent QC process wrt the M8 are not what Leica nor, more importantly, its loyal customers want right now. Also, the constant analysis to try and determine what is wrong can be a real drag. You start off thinking that you have done something wrong, unlearned how to focus, and then you find it is the mechanics that are at fault. It would be so much simpler if the camera was a dog. Huw Huw--so sorry to hear about the backfocus problem; let us know once Leica straightens it up for you! Jamie Link to post Share on other sites More sharing options...
wlaidlaw Posted July 8, 2007 Share #24 Posted July 8, 2007 So - Geduld, und nochmals geduld Patience is a virtue, I guess. Huw Patience is a virtue Virtue is a grace Grace was a little girl Who didn't wash her face To h**l with patience, I just want my lens back mended properly and it would be nice to have the 60mm filter to go with it..

pklein Posted July 9, 2007 Share #26 Posted July 9, 2007 All this talk about lenses coming back from Leica less well adjusted than before has me a little worried. It's good to know that they are trying to fix their alignment process, but I hope they get their act together quickly. All this does seem to confirm that the M8 is simply more critical about lens adjustment and focus that the film Ms were. And at the pixel-peeping level, we can see flaws that we never saw with film. Welcome to the Brave New World. The good news is that many "problems" you can see at 1:1 with an M8 would be smeared over by the anti-aliasing filter of any DSLR. And you probably won't see these "problems" at the sizes most people print. None of which helps the people whose lenses are truly "off." My 35/1.4 ASPH backfocuses slightly at f/2.8-5.6, but it's on the order of what Sean Reid found in his tests. So it's OK. For real photography, it doesn't usually matter. I'm inclined to wait on sending it to Leica for coding. I'd rather deal with the occasional cyan corners with CornerFix that be without my lens for several weeks, only to have it come back misadjusted, and then be without it several months. If a lens really needs adjusting *now* and it can't be coded or doesn't need to be (non-Leica lens, old lens, or lens 50mm or longer, you might try your friendly independent Leica-knowledgeable repairman. Or a combination of Milich mount milling and a repairman's adjustment afterwards if needed. I had a chat with DAG recently. He told me that with the M8, there's no such thing as a perfectly adjusted lens anymore, which bothers him. But there are compromises that will make the lens perform well at all apertures. He has an M8 which he knows is correctly adjusted, and he uses it to test the lenses he adjusts. Based on what I've heard so far, I'll probably send my 35/2 Summicron (not aspheric) to Leica, because it needs both adjustment and coding. A couple of other lenses will go to DAG. And my 35/1.4 ASPH is not going anywhere until Leica has its adjustment procedures together. Fortunately, I have lenses that work well at my most-used focal lengths, so I'm OK. I can only imagine what it's like to wait months for one's only 35mm or 28mm lens to come back from Solms. --Peter Link to post Share on other sites More sharing options...

Then when you get the lens back, all you need is two pots of modeling paint and an instrument maker's extra fine camel hair brush. No need to send it across the pond and if Dan does the lens, you know it will be about as right as it can get. Wilson Link to post Share on other sites More sharing options...
huwge Posted July 9, 2007 Author Share #28 Posted July 9, 2007 Decided to be a bit more disciplined this morning, as I think I may have been a little cavalier the last time: so 35 cron asph at f2 vs 35 lux asph vs 50 cron (rigid, made in 1957). Tripod / remote release and tripod not moved. 50 just included to show that it's not my focus error and also to reflect that it is not the camera body. The 35 lux has just come back from Solms, coded and allegedly serviced. At f5.6 it's just peachy, but it's wide open where I want it to work. Also, as with Wilson's Nocti, the error is not consistent with distance, at infinity things seem OK These were taken with AWB as jpegs so please forgive the colour Welcome, dear visitor!

carstenw Posted July 9, 2007 Share #29 Posted July 9, 2007 That's quite some backfocus with the 35 Lux. That's wide open, right? How far from the camera? Link to post Share on other sites More sharing options...
wlaidlaw Posted July 9, 2007 Share #30 Posted July 9, 2007 I know Solms and others are saying the M8 is far more critical on focus that previous film cameras but I have to believe that that Lux would be miles OOF on film too. How CAN that have passed initial let alone final testing? Wilson Link to post Share on other sites More sharing options...
carstenw Posted July 9, 2007 Share #31 Posted July 9, 2007 If that's really wide open, god only knows. I believe that they test the focus wide open at 1m 10m, and an artificial infinity, believing that the rest will follow, but this lens is just way off. There was clearly an error here. Maybe this is a Friday lens. Link to post Share on other sites More sharing options...
huwge Posted July 9, 2007 Author Share #32 Posted July 9, 2007 This is at roughly 1m, just a little short maybe. I just don't see why I should spend any more time trying to show where it works and doesn't work across the range. It is OK when you get above f4, but that is not what this lens is for. It is an inconsistent performer which makes it difficult to nail down the exact error. I just wanted to include the other files to show it's not user error. I also have 75 lux and 90 apo, all wide open and focused. At the shop today they wanted to ship the camera as well, but with the turnaround time and the fact that other lenses work to spec I will not do this. I can't see how this lens would have passed any proper form of QC and I wish that I had done more wide open testing before. It's just that most opportunities have been in bright light and didn't merit wide open apertures. The glass is unmarked and there are no scratches. It really is worse than before the service / coding. Link to post Share on other sites More sharing options...
wlaidlaw Posted July 9, 2007 Share #33 Posted July 9, 2007 I think it is getting very near to stage of a forum letter to Mr. Steven K Lee, the chairman. I and many others can forgive and understand delays and iffy administration. That comes with the territory of the company having been run down too far under the previous ownership /management and the current roaring success of the M8, with consequent high demand for lenses. However, a serious breakdown in the quality control of what is after all, Leica's bread and butter business of making and servicing lenses, that has not changed for donkey's years, is inexcusable and disastrous. How many posts have we seen of lenses going for servicing and coding, coming back all out of kilter - dozens. This is not case of one or two isolated instances, this is a significant percentage of lenses coming back wrong. How many brand new lenses not right - quite a few. The aperture ring on my new Elmar-M 50 is so loose a puff of wind will almost blow it round. Wilson (Colonel Bristling-Moustache de Tourtour) Link to post Share on other sites More sharing options...
