leicashot Posted July 19, 2010 Share #81 Posted July 19, 2010 Advertisement (gone after registration) Gotta say the 50 Lux asph is so well corrected it's boring next to a Noctilux but it allows the focus to remain the special part of the image and not the other way around.if it has any character or signature it is that it's technically perfect and is THE lens to compare everything else against at any focal length of 75mm and under Link to post Share on other sites More sharing options...

tashley Posted July 20, 2010 Author Share #83 Posted July 20, 2010 OK, this is the replacement lens. Both shots on a tripod and with timer release. I shot a series of five frames where I threw the focus totally off each time, then focussed about right, fairly quickly, then to varying but very small degree pulled focus a touch closer and shot the frame. Then Five frames where I tried to focus exactly. Then five frames where I focussed slightly too far away. Point of focus is the round window in the building opposite. All the 'pulled closer' shots were sharper on the round window than all the 'exact focus' shots. This was at F4 (it had to be because it was quite bright!) but bear in mind that tests on this exact subject using the lens on an Oly Pen and magnified live view focus show that there's effectively no focus shift as you stop down. I post the 'Pulled Closer' shot first, then the 'accurate focus' shot. But don't just judge on the sharpness on the round window: look around the frame. You might be surprised by what you find... http://tashley1.zenfolio.com/img/s9/v15/p179501073.jpg http://tashley1.zenfolio.com/img/s8/v10/p144037860.jpg Link to post Share on other sites More sharing options...

tashley Posted July 20, 2010 Author Share #86 Posted July 20, 2010 p179501073 looks sharper in background and softer in foregroud. Are you sure it's the "pulled closer" shot? The fist one is certainly the pulled closer shot and I agree with The Emporer's post - to me it is very clear that it is sharp on the round window and soft at the peripheries, where as the second shot, focussed exactly on the round window, is soft on the window and sharp elsewhere. This is not focus shift, it's a spherical focus differential and I noticed it on the previous gen 35 Lux too, though its effect was usually obliterated by focus shift... but in real life this new lens seems not to show the effect on closer subjects - in teh follwoing selection, 85% quality JPEGs and full-sized except for some minor straightening, the point of focus is always where I placed it and seems pretty good, and the bokeh is quite nice too! http://tashley1.zenfolio.com/img/s9/v14/p706944926.jpg http://tashley1.zenfolio.com/img/s9/v15/p934832622.jpg http://tashley1.zenfolio.com/img/s8/v9/p916222000.jpg http://tashley1.zenfolio.com/img/s8/v9/p570034212.jpg http://tashley1.zenfolio.com/img/s8/v9/p570034212.jpg http://tashley1.zenfolio.com/img/s9/v13/p931885488.jpg http://tashley1.zenfolio.com/img/s8/v10/p1041985286.jpg Link to post Share on other sites More sharing options...

Hi Tim I've found that in practical terms focusing works . . . and also that in most normal circumstances the bokeh is pretty good as well. The one place where it seems 'nervous' is in partly out of focus high contrast busy backgrounds (like foliage), and I've not come across a 35mm which doesn't do that (including the famous 35 'cron IV).

wlaidlaw Posted July 20, 2010 Share #94 Posted July 20, 2010 On a focusing related matter, there is a bright planet just about 10º above the western horizon tonight in Southern Europe, perfect for RF checking. I think it is Venus, as I can't see any moons with my 45 power spotting scope but astronomy is not one of my skills. On my M9 with a selection of lenses, horizontal alignment is just about perfect. Maybe if one was being ultra ultra fussy, the images could converge a tiny bit further but vertical alignment is off just enough so that it is difficult to judge. I had noticed that I did not seem to get the same degree of contrast "pop" on perfect focus, that I get with my M8 and M4, so I am guessing that the vertical alignment is the reason. I am reluctant to lose my M9 for three to four weeks to get this corrected but I think it would impact the warranty if I were to remove the red dot to do it myself. In that so many things are inter-related in the RF, I am not 100% sure that adjusting the vertical alignment, does not require compensating adjustments elsewhere.

wlaidlaw Posted July 21, 2010 Share #100 Posted July 21, 2010 LCT many thanks for the suggestion. I will give them a ring today and see if they can guarantee to get it back to me by the 9th of August, as I go back to the UK on the 10th for my wife's 60th birthday party on the 14th. I have been told that I am photographer in chief for that and I would prefer to use the M9 to the M8, due to the wider coverage of my fastest lens, the 35 Lux.
