Thank you Thorsten for that spec of light.

🙂

[@Gundolf300]

It became a bit clearer now why so many people preach optics before housing. Great learning video!

[@jamespalsson746]

Quarantine gets a bit brighter, when a video from Thorsten pops up

[@MagicOfLight_ThorstenOvergaard]

Thank you, James

[@ruhnet]

Agreed!

[@kenj2020]

This is my favorite Thorsten video

[@MagicOfLight_ThorstenOvergaard]

Thank you!

[@johnblunt1834]

People seem obsessed with lens sharpness rather than image quality. A strange obsession in what is an artistic medium. Well explained in your video. A nice treatment of the subject, thank you.

[@Dark_Viking]

Totally agree with you! Sharpness is fully subjective. It is only a person's comprehension which determines how sharp the image is. Especially this situation is funny when people talk about sharpness of images that should be published only in social media.

[@jamesfitzpatrick6100]

Very interesting and helpful. Obsession with sharpness can spoil what's really important in a photo. Much like a painting or a poem, it's the emotion or feeling you get from a photo means more than how technically perfect or otherwise it is. The best photo isn't always the sharpest, in fact rarely is I'd say. Of course careless ,accidentally out of focus images are not what we should strive for !

[@searam1]

I am a fan of your artistry! Thanks!

[@martinparker5872]

Great explanation on lens sharpness. Thanks for the uploaded video.

[@MaikKronerPhotography]

Thank you very much 🙏🏽

[@The_Essential_Light]

Brilliant as always!

[@MrBillboeing]

Thank you, very informative and so true!

[@ruhnet]

Enjoyed this video for the second time!

[@serkanreis]

Pretty sure I've seen this exact video a couple of years ago. A glitch in the matrix it must be.

[@MagicOfLight_ThorstenOvergaard]

It's a repremiere, yes

[@TomVestvik]

But some messages has to be repeated too …

[@shanepeter351]

dont know if you guys gives a damn but if you are stoned like me during the covid times you can watch pretty much all of the new movies on InstaFlixxer. Have been binge watching with my gf recently :)

[@troyrayan9554]

@Shane Peter definitely, been using instaflixxer for since december myself :D

[@cdsreenath]

Superb! Well explained. Thank you.

[@fabriziobatisti9439]

This is a good point Thorsten, I have an M8 and for me 10mp it's enough, my photos is always sharp, I don't understand why people like me that look the pict on computer or post his pict on instagram or print A4 need to buy a camera like Sony A7Riv or SL2. I like the SL or M10 but If they have 12-14 mp would be much better.

[@jan-martinulvag1953]

A7s is 12

[@ibrahimz]

Great channel and I subbed for sure. I couldn’t find a review on the M10 Monochrome despite your strong link to Leica. Is it coming soon ?

[@MagicOfLight_ThorstenOvergaard]

There's a written article on Monochrom Photography evolving now, so yes. Soon :-)

[@ibrahimz]

Magic Of Light fantastic and looking forward :)

[@jan-martinulvag1953]

I have 15 cameras and they are good for what they are but if I want to photograph my paintings they are almost unusable. A painting not bigger that 1x1m is way to big for my cameras. They look mushy and weird when i zoom in.

[@ucevrim]

One cannot enhance resolution of the lens without affecting other variables such as micro-contrast which directly influences tonality in a photograph and images people get with the sharpest modern lenses on the market are the clear indications of the consequences of maximizing a specific value on a lens. You can't have everything. Photography is the mariage of art and technology, relying on one extreme too much to find answers is dangerous.

[@srkgv]

Can "old" leica lenses handle 41 Mega pixels+?

[@weizenobstmusli8232]

If you look at MTF: no. But if you look at pictures, you will be surprised. I have some 60 years old Leica lenses adapted (so not perfect like on a M or SL) to high mpix cameras. And under good lighting conditions (no flare!) I am very often blown away what comes out of these old lenses. Color correction is mandatory 😉 abberations apear easy on digital sensors. But thats what lens correction algorithms are for. So answer is: old lenses give fantastic pictures, but you have to take some effort in post.

[@MagicOfLight_ThorstenOvergaard]

Yes, generally they can. The resolution of new lenses from the 50mm APO are double compared to previous lenses. What it means is the resolution power of details, measured in lines per mm that a lens can resolve. For an overall picture it doesn't mean much. Lens designer Peter Karbe said, when we spoke about the SL lenses and new M lenses that, "The closer you go, the more you see" when talking about new lenses and sensors. Which translates to that you can take a 41MP picture and zoom in very close, and it will have resolution and details as if you have been standing closer to the subject. Not much practical use, but if you want to compare to medium format, that is the quality of that format. So in a way, with a newer Leica lens and a large sensor with lots of MP, you have a medium format camera in a small camera.

@@weizenobstmusli8232 Thank you!

[@srkgv]

@@MagicOfLight_ThorstenOvergaard First of all thank you for the reply. I really appreciate it. Thank you for your explanation. So technically, I can still use my 50 Summicron V or 35 Summicron ASPH on the SL2 or new M with high mega pixel in the future with no noticeable difference in the over-all picture. But, I cannot crop further because the "details" will be not quite good. Is this correct? Thanks

[@weizenobstmusli8232]

@@srkgv , your picture is still 41mp, but fine details look mushier than with a newer lens, when you zoom in or crop.
