pascal_meheut Posted May 15, 2010 Share #41 Posted May 15, 2010 Advertisement (gone after registration) Once again, you are comparing a 6 Mpix with a 18 Mpix... The point of Artichoke exactly. Not to mention that the DOF of your picture does not look like the equivalent of a 50/1.4 on a FF... Link to post Share on other sites More sharing options...
Advertisement Posted May 15, 2010 Posted May 15, 2010 Hi pascal_meheut, Take a look here M9, 50Lux ASPH 100% crops. I'm sure you'll find what you were looking for!
lct Posted May 15, 2010 Share #42 Posted May 15, 2010 ...Not to mention that the DOF of your picture does not look like the equivalent of a 50/1.4 on a FF... Far from that (Nikkor 280/4 @ f/4). Sorry but i have no FF pic at f/1.4 unfortunately. Not sure if i would find a sharp lens like the 50/1.4 asph though. Link to post Share on other sites More sharing options...
lct Posted May 15, 2010 Share #43 Posted May 15, 2010 Don't want to bother you with my problem. Just to show what i mean. I would expect results like this or better from the M9 as at full aperture the Lux-M 50/1.4 asph is not soft at all. Canon 5D, pre-apo Summicron-R 90/2, f/4, 100% crop, default sharpening of C1v4.

Canon 5D, pre-apo Summicron-R 90/2, f/4, 100% crop, default sharpening of C1v4. glad you recognize this as your problem & not one of the camera or lens nice of you to tell us what lens & camera were used as well in your earlier post wide open the 50 Summilux ASPH is hard to beat, but as you were questioning the sharpness that can be had with this lens on the M9 (and supported your arguments with shots taken with another lens using default sharpening without offering the full frame image from which the crop was taken ) let me offer up this example which is straight out of C1 5 with sharpening off & no adjustments made from the default settings I only changed the file to 8 bit & converted to SRGB for the web this was taken from the center of this snap taken from a recent trip I have two other straight 100 % crops from this shot that demonstrate some other properties of this lens/camera combination, including moire & CA as well as shooting information here technique Photo Gallery by Artichoke Vinagrette at pbase.com in such a discussion showing crops & not showing the file from which they were taken has little value the 18 MP CCD along with the lack of an AA filter (and fine M glass) produces files that rival & often surpass those from my D3X Link to post Share on other sites More sharing options...
250swb Posted May 15, 2010 Share #45 Posted May 15, 2010 I have to use an amount of 50 in Lightroom to get tack sharp images @ 1.4. I'm fine doing it, but since it's supposed to be the sharpest lens available, I am wondering if i even have to do it. I'm also trying to identify it the lens is within tolerances so I can send it back to Leica if I don't believe it is. Thanks! Assuming you are using .dng (RAW) then yes you will need to add some base sharpening to see the crisp image, just as the camera would by default when using JPEG. You are dealing with an unprocessed image and Lightroom sharpening is very conservative in its default settings. Ideally you should sharpen depending on the final print size at the very end of post processing, but try 100 in Lightroom and see if that sharpens it up. Also keep in mind you are shooting at f1.4, so its unforgiving and even for the Lux is outside its sweet spot ('lens character' aside), so try it at f4 or f5.6 like Jaap has shown. This should confirm if its sharp. Steve Link to post Share on other sites More sharing options...
lct Posted May 15, 2010 Share #46 Posted May 15, 2010 ...without offering the full frame image from which the crop was taken ...

wattsy Posted May 15, 2010 Share #47 Posted May 15, 2010 Advertisement (gone after registration) Why do i have the feeling that the M9 is a somewhat soft camera? I was a little disappointed that the M9 seemed a little less sharp (at the pixel level) than the M8 I had used for nearly three years until I realised that it was front focussing a bit. Not enough to be screamingly obvious but enough to impact on sharpness. Solms re-calibrated the rangefinder and all is now well. A number of the shots in this thread (e.g. Pascal's) do look a little unsharp by the standards I am used to from the combination of M9 and 50 Summilux and I suspect that the focus is not all it could be.

Sorry but this is not the case. I posted a crop where the focus plan is obvious. Also, I'm quite sure that my M9 RF is perfectly calibrated with the 50/1.4 ASPH has it has been tested several times by the Leica serviceman, by DxO when they used it for their M9 report and by a friend writing a book where he tests around 80 lenses on it... So you must look the lips for instance and discover that you can see a fallen eyebrow on them not much larger than 1 pixel. And take into account that you cannot compare a low constrast children portrait with the beard of a grown-up shot under sunlight for instance.

And take into account that you cannot compare a low constrast children portrait with the beard of a grown-up shot under sunlight for instance. Fair enough. I wasn't comparing anything with a bloke's beard but had made an assumption that you had focussed on the child's eyelashes. Here's my own M9 + 50 Summilux 100% crop contribution. Converted in CS4 with default settings. Link to post Share on other sites More sharing options...

Looks OK with Epson and Canon pics on my various monitors. Nikon's are sometimes better with Nikon View but C1 is better on noise. I just add a bit of sharpening with Fred Miranda's apps when i print larger than A3 with the 5D. Link to post Share on other sites More sharing options...
jaapv Posted May 15, 2010 Share #55 Posted May 15, 2010 Found it; for M9 I normally use 40, 1.0,1.0. C1 puts the 5D at 130,08,1.0. So there is quite some sharpening going on by default on the 5D. Link to post Share on other sites More sharing options...

So there is quite some sharpening going on by default on the 5D. Agreed, Jaap--the 90mm post looks sharpened, not particularly sharp--not that it isn't perfectly usable (and of course it's not at f1.4 either, but rather at f4(!!), so the comparison is a little weird ).
