sharpest Leica lens?

adan,

I can not answer a question a I do not know the answer to. So, I add my

humble opinion for whatever it’s worth.

The Leica Q3 is available for pre-order at B&H Photo Video and Adorama

I have both lenses and cannot agree.

Take a tripod, the same light and talk again.

By the way, why not compairing 35 to 35?

Greeting,

You always use a sturdy tripod then?

 

Not always? Does it still make a difference, if you shoot at speeds above the limit? For instance for a 50mm I use 1/500.

I recently got the 28 cron mounted on the m8. Love the rendition. Definitely sharper than Canon 16-35mm mk2. However 35L is definitely sharper, with less CA. Same white balance on both cameras, 28 cron gives better contrast, which I love

 

What would be the sharpest leica lens lineup?

 

Do you know the site of Erwin Puts?

 

I learned a lot from him. Not that I became a better photographer but now I know what's for sale.

 

Summilux1.4/50 asph

I think it more likely that the 50mm ASPH Summilux was the starting point.

 

I agree with the others that there are so many variables that it's not really possible to answer the OP's question. If lens A is sharper than lens B at f2, but lens B is sharper than lens A at f5.6, which is the sharper lens?

 

 

 

According to Erwin Puts site and his new book , you are right. The 75 cron stems from the 50 smluxasph.

 

And I must say, when you use the new generation IV lenses, it will be very difficult to see the difference in practice between the sharpness between them.

A 21mm lens will produce sharp photographs more often than a 90mm lens used under the same circumstances, with similar speeds, and similar f stop. The average is reduced but a 28mm will be sharp more often compared to a 90mm lens, and even more reduced a 35mm compared to a 90mm, and etc. While totally useless to making a good photograph these simple rules apply if you are not using a tripod, or photographing a wall or test chart, but are outside in the fresh air with your camera trying to do something worthwhile.

Ok there is not actually a limit, the 1/125 with a 5cm 1/250 with a 10cm are advisorys and assume you are using both hands, legs apart. breathing carefully, and dont have any medical problems, and - are not being critical, it is for family snapshots, or news paper printing.

 

If you want to detect lens performance differences you need to be more careful or you will influence the results.

 

If you want large enlargements similarly. If you have not a tripod and cable release brace against a tree, pillar etc. (Or switch on the anti shake.)

 

The MTF which are available for lenses make lens testing for resolution a waste of time but it is still meaningful for focus accuracy or veiling flare.

 

Leica Camera AG - Photography - LEICA SUMMARIT-M 50 mm f/2.5

 

These MTF are only of the lens, they dont include film, (or sensor) effects, camera shake, post processing (sharpening), wet printing or scanning etc., etc.

At 40 cpmm the CN400 will be degrading contrast, so the 40 cycles on the lens MTF is 'illusary' without shake or other real world effects added in. You can do similar sums with the micro lenses on M9.

 

If you want to do big enlargements you will need to use slow film e.g. PanF and an edge developer, tripod. If you want snapshots you dont need a modern lens or slow film.
