Woody Campbell Posted May 15, 2007 Share #21 Posted May 15, 2007 Advertisement (gone after registration) Mine focuses perfectly - at f1 the camera focuses at the front of the zone of good focus. This lens, plus ISO 2500 plus working the noise slider in C1 let you go places that seem impossible. This, from the night before last, is lit by two candles at a distance of about 1.5 meters.

Advertisement Posted May 15, 2007 Posted May 15, 2007 Hi Woody Campbell, Take a look here M8 and Noctilux. I'm sure you'll find what you were looking for!
wattsy Posted May 15, 2007 Share #22 Posted May 15, 2007 plus ISO 2500 plus working the noise slider in C1 let you go places that seem impossible. Personally, I think the noise slider in C1 should be left well alone (at the low setting). I think the noise reduction tends to rob most high ISO images of all their character (and detail).

wlaidlaw Posted May 15, 2007 Share #23 Posted May 15, 2007 I have run tests on the following lenses and the results are a bit disturbing. 35 Biogon at f2 front-focusing noticeably (ie sharper nearer the to camera from the focus point than further away) but correct at f4. 50 Elmar-M Noticeable back focus at f2.8 - worse at f5.6. 50 Noctilux very slight back focus at f1 but quite soft; back-focus increases substantially at f2 and further at f5.6. Actually almost out of focus at focus point with all the DOF further away from the focus point. 90 Elmarit-M Spot on at f2.8 very slight back-focus at f5.6. All measured at 45º and 1.8m distance on a Manfrotto 190 + RC141 head and cable release with 1.25 magnifier. Wilson Link to post Share on other sites More sharing options...
jackal Posted May 15, 2007 Share #24 Posted May 15, 2007 best advice is to get out there and enjoy it imo many focus errors shooting brick walls and the like are user error...... with the F1 lens there are so many parameters that can go astray, the margins are really so tight. when i first got my noctibang one of the first things i did was shoot about 20 pictures of a 6 month old kid, they were all pretty much the same.. the focus looked bang on in the viewfinder for each one, subject at minimum focus dist. get them into photohsop ....every single shot was out of focus reason: user error Link to post Share on other sites More sharing options...

My tests were all in fact with the Nikon D70 focus target but blown up to A3+ I am going to try Sean Reid's test of the three wine bottles. He says it is more realistic and as you empty the wine bottles you get to the state where you really don't care anyway Wilson Link to post Share on other sites More sharing options...
jackal Posted May 15, 2007 Share #26 Posted May 15, 2007 yep getting to the 3 bottles is probably the important bit seriously though i was talking more about the Noctilux rather than responding specifically to your post sounds like your issues are more widespread Link to post Share on other sites More sharing options...
Eoin Posted May 15, 2007 Share #27 Posted May 15, 2007 Advertisement (gone after registration) Wilson, I love your humor,LOL, Just for pig iron you should try to focus without the 1.25x. I think I've suggested this to you before. I've noticed miss focus with the 50 FL and 1.25 and perfect without. I've also tried 2x 1.25's stacked and results were perfect also. I'm still trying to figure that one out . Link to post Share on other sites More sharing options...

I have just tried a few with the wine bottles (just a couple to steady me 'ands guvnor - honest) and I am more on focus without the 1.25x magnifier than I am with it. With it I am consistently back focusing by about 3-5 cm at 1.5M. Well that was a waste of £200! Here is the example without the magnifier lateral bottles are about 2-3 cm in front and behind the central one taken on Leica table tripod at f1.0. Wilson Welcome, dear visitor!

Have your lenses code tagged & and adjusted at Leica. This will, most likely, correct the problem. I Link to post Share on other sites More sharing options...
