Apo Summicron 35mm

[raid]

Are there major optical differences between the Leica 35/2 APO and the CV 35/2 APO ?
There is a $7000+ difference in the prices.

Petapixel must really like the word "haptic," because the sentences mean the same thing if you delete the word. 🙄

Nice that they chose the same hood design as the Q.

I take the 0.3m minimum focus as another hint that they will make an EVF only M-mount body. There's a larger market for TTL viewfinder cameras, with only a few who actually appreciate reverse Galilean viewfinders.

Or just an acknowledgement that M mount lenses are increasingly being used on mirrorless bodies.

Yes. I see this as a sign of a rangefinderless M11 or M12 or something like a FF CL.

 

[aizan]

That’s true. It points to the demand for using the relatively compact yet high performance M-mount lenses on bodies that have an EVF. I believe Leica will eventually make an M-mount camera to meet this demand.

I have to assume the same... they have to realize that many of their older customers feel an evf offer the best VF for those who have failing eye sight.

I would like to know if the Chinese will copy this lens too, say, sixty years from now.


Erik.

A equivalent should be on the horizon within 5 years.

I do wonder though if the APO-Summicron will attain the same cult status as the 35cron v1 that can warrant a replica in the distant future.

If the differences are similar to those between Leica and Voigtlander’s 50mm apos, yes, there will be major differences.

Now I know about the focus detent it is a lot more tempting.

Seeing that Leica, CV, and TTartisians are all pumping out the 35mm FL @f2 this must be where people spend their cash. Good to see Leica with a new lens with stellar performance setting the bar higher for this FL and aperature. Close focus of 30cm a Brucie bonus (UK guys will know that meaning) to be used or not. I have used the 50cm close focus on ZM and CV with my Zeiss ZM, it can be done and I have found and easy way for me to do it.
However, I am happy with my ZM 35mm f2.

Next 28mm f2 APO, one from Leica and one from CV?

Have you shot with both the Leica and Voigtlander 50mm APO lenses and found the Leica to be greatly superior?

In the 35mm APO Lanthar review on dc.watch.impress, at the end of the article the author says it sounds like Cosina is considering a series of Lanthar lenses, and that he's excited about the possibility of focal lengths other than 50mm and 35mm being released.

I’m (academically) interested in this too. From a resolution/evenness perspective, I’d be surprised if the Leica is noticeably different. The VM is pretty much pixel sharp at f/2 on my M10M... maybe future higher resolution sensors will show weakness in this area. Distortion seems well controlled, etc.

I’m sure there are differences, but I would imagine them to be more second order things like bokeh, color cast, etc. I’ve seen lots of comments on how different the two lenses are, but not much in the way of demonstration.

I would like to see such demonstrations.

This is coming from someone who owns and shoots the Leica APO 35 Cron-L: what I present is just my speculation.

So my APO 35 Cron-L is optimized for wide open shooting. No reason to stop down unless more DOF is desired. This is what is meant when they say "diffraction limited." This is another way of saying that resolution is perfect. These are very highly corrected lenses (APO Crons in "L" mount).

I find that I mostly shoot with the lens wide open.

There is an APO artifact of the in focus parts of the image where the in focus parts of the image have enhanced contrast, and as a result and since our eyes perceive contrast mistakenly for sharpness the in focus areas seem sharper.

On my APO 35 Cron-L what also gets accentuated is also the OOF areas and the smoothness of the bokeh. The smoothness of the transition is remarkable.

Will Leica be able to recreate this in a smaller lens?

The wide open rendering is kinda magical, especially on close focused subjects.

So I wonder did Leica recreate all this in the APO 35 Cron M-lens?

Also is this artifact of contrast enhancement on in focus parts of the image also translate into the CV APO's?

The APO Crons in "L" mount all have this in their rendering. These lenses seem very highly corrected and are "future proofed" some say to 120 MP. Their expense is kinda paying things forward, so the big price tag now over time might be the cost effective way to go.

A Leica employee once told me that the lens on a Leica "Q" is already future proofed to an 80 MP sensor. How many steps till we get there?

All I'm saying is spending your money only once might be cheaper over the long-long term. Also I own the massive 50 Lux-L; and all I really need are these two lenses:APO 35 Cron: and 50 Lux-L.

Currently I have both a SL and a SL2, and hopefully Leica creates a SL2 Monochrom, but I'm future proofed out perhaps 2-3 generations of sensors till 120 MP is reached.

So I wonder how much of my APO 35 Cron-L will trickle down to the APO 35 Cron-M.

Thank you, Cal. Time to save money 🙂

Realistically speaking, if you are not using photography as a professional (for income), spending $8000 for one lens with the goal to get the perfect lens may be an overkill, in my humble opinion.
In theory, it makes sense to get what Cal has gotten, and to use such amazingly perfect lenses, but as a hobby, it would be too costly for most people.

Is APO so important in wider lenses? I seem to remember that chromatic aberration is more problematic with longer focal lengths, say above 90mm. In fact there's an old Peter Karbe interview where he claimed that the 50/1.4 Asph was also an APO lens but it would be silly to market a 50mm lens as such.

T,

Your point that APO matters more in longer lenses is valid and correct, but with my APO 35 Cron-L the APO correction is very evident, especially on a SL2 with 47.3 MP count.

As sensors develop and evolve to higher MP counts of course imperfections will get more exaggerated.

Raid,

You should know that I am not a working pro and that I have a day-job.

I hope to retire at the age of 64 nine months from today.

My thinking is that the expensive glass has a future and will be like spending my money once.

Some people will go out and get a fast car they don't need but are drawn to because they want the experience. Life is unpredictable and at some point, especially in these abnormal times, indulgence is a balm for sanity.

BTW, buying full retail isn't invariable. Have a couple of really cool pieces I was able to acquire for far less, like the 50 APO. Patience and ingenuity.
