Official Talk Leica thread

Hi, a personal comparison ... (SONY A7R2) :


DSC00720-a7r2-4c.jpg



DSC00981-a7r2-4c.jpg


(#1 with the SONY/ZEISS 1,8/55, #2 with the SONY/ZEISS 2,8/35, both at 2,8, cropped. IS and AF of the A7R2 are more convenient to use.

But even a low-res cam like the M9 has good IQ, even when cropped at 100%. Which is why I enjoy using both systems ... )

My problem with shooting cars on a low resolution camera (EOS 1D mk2) was often pin stripes and body seams which would show not as smooth lines but as jagged edges this was more apparent if the car was or was moving diagonally to the camera. I have not done any historic motor sport since I moved to using 24 / 32 Mp cameras but it would be interesting to prove or disprove my theory at some point.

Hi, cropping with a low-res cam (M9) can lead to CAs and loss of IQ. Higher res helps, of course ... :

I was forgetting that the M9 is a CCD sensor which probably explains the difference in how it is resolving the same problems that I had with the EOS 1D. I can't find a good example in my Flickr as I only posted small images at that time.

Hi, I am not sure, what difference CCD vs. CMOS makes in resolution. I found a few SONY A7 (24MP) pics coming a little closer to a comparison with the M9.

There are many different factors, of course, here. M9 pics are DNGs (Leica RAWs), converted by DxO into JPEGs, no further post-processing. SONY pics are JPEGs,
picture mode STANDARD (contrast +2, saturation +1, sharpening +3), no post-processing.

500K forum pics do not show much difference ...

I was assuming the lack of Anti Aliasing filter on a CCD reduces the need for sharpening hence the spectral appearance as opposed to the jagged edge effect with CMOS after sharpening in editing.
Just my guess work, I can't quote anything scientific.

Hi, the same goes for me ... And there seems to be no official SONY information on AA filters:


The A7 is said to have a weak filter, above. -

But I did not show a proper comparison, there was too much variation.

All I can say with some certainty is that good modern cameras with modern lenses lead to similar results in the hands of an amateur.

So, one should not worry too much about equipment, perhaps ... ---

The fantastic Jerbane Cafeen aka Railroad Pub, this is next to Copenhagen Station, and was only about 100m from our hotel. A warm cosy traditional Danish pub (that is very lively), that has a house beer, live music, model railway and a wall of model trains. What's not to like? :beer::D

'Talking Leica' rather than just posting pics - new Firmware out version 2.2.0 for M11 & others with good improvements to the Fotos App. (y)

Hi, to do a little Leica talking ... Too much difference, I am afraid, no ceteris paribus. - For my rather modest attempts, different equipment does not lead to greatly
different results. Which can mean that I do not manage to bring out the performance differences, or that it can be taken as another example of real life.

Good lenses do not show great differences. A 400 hp car does not take you to your destination in traffic faster than an 350 hp car ...

I am more a user, not a talker ... ---
