I'm trying to rekindle some enthusiasm, so I found a cheap APO-Lanthar. Since I have the Elmar already, the two went on the NEX-7 for a quick test, F4 and f5.6 only. First the lenses

Here are the two at f4 first, APO Lanthar then Elmar, then both at 5.6. Elmar is less contrasty and is of lower resolution. The Lanthar is pretty nice. Will have to compare it to a Nikon 85/2 D and the Tamron Adaptall-2 90mm macro.
#1 Lanthar f4


#2 Elmar f4


#3 Lanthar f5.6


#4 Elmar f5.6

The obligatory 100% crops, birdhouse and top right corner from the crop sensor.

Beautiful lens. I like how apparent image quality has evolved from the Elmar.

The Elmar looks a little bit disappointing. Did you use a sun shade? Unfortunately I've destroyed mine during a cleaning attempt.
However, I've replaced it with the Elmarit 90/2.8 which IMHO beats the APO Lanthar slightly.
I've compared my 90mm RF lenses here: http://forum.mflenses.com/90mm-rf-lens-comparison-leitz-topcon-voigtlander-t80008.html

Agree with Thomas and estonished with a kind of light purple cast in the shots taken with both lenses. Is it normal for an APO glass?

I had Leica M version of M, and LTM of Lanthar,
I compared both here https://ihyaahsani.blogspot.com/2011/08/voigtlander-apo-lanthar-90mm-f35-mc-ltm_04.html
I found my elmar was better handle CA.

That old Elmar's low contrast (assuming there's no haze to degrade the image) appears best suited for B&W. Very unappealing for color. From the images provided above, it does not look to be a clear & clean optic.
