This is a newly acquired lens in C/Y mount on my Contax AX.

The slide, under the loupe, is superbly sharp and contrasty. Shocked

Although it's difficult to scan 35mm film properly with the flatbed, I still think that there is a certain
look to the results from the lens that is pleasing to me. I guess I can describe it as 'saturated and
deep'. I may be going out on a limb, but I think the rendered image has much the same 'feel' as the
Zeiss T* Makro-Planar that I owned a couple of decades ago.

I don't hear much about this lens, but the results, at least on the slide, are outstanding.

This is, of course, just a test shot looking straight down from an elevated position, into the mix of sticks
and stones. It possibly would benefit from post-processing such as Unsharp Mask, but it seems to have
rendered nice and sharp as it is.

Depth of field is pretty shallow with this lens; it might have been more expedient to stop
down to f/5.6 or so.

I'll post more, including macro mode (2:1), as they are scanned.

With flatbed scanner need sharpen a lot scanned .tiff file, usually works quiet well. Famous and rare lens, congrats!

Yes, excellent find. I don't see them around. Tomioka?

Thanks for the scanning tip, Attila!

woodrim: Perhaps someone who knows the lens origins could tell us if it is made by
Tomioka or some other production company? The lens is incredibly compact for a
100mm macro. It extends from both ends when focusing down. The coating seems
to be really well done, with a coloring of purple and yellow from the coating reflections.

Excellent result Larry! That lens really is an outstanding one and some mentioned that it rivals the Zeiss 100mm Macro Planar. I had both lenses and both are outstanding performers indeed.

Thanks Klaus! I put this lens on a par with the C/V 90 SLII. Shocked In fact, I'll take some images with
both for comparison. I know...the web is a POOR place for any comparisons, but it's still kind of fun to do so.

You can upload full size of jpeg from both lens , no limit and we can look both.

The C/V 90 has wonderful short focus capability, so I can pretty well match up the subject
matter.

Attila, thanks. I will keep in mind to bring out some comparisons for fun.

hello all,

this lens , the ML 100/f3.5, were the first manual that i adapt to an DSLR
a this time , 4-5 years ago,i bought a EOS 30D and start to be interested by using manual lens instead of auto-focus,and a french forum member offered it for free (gift)
at this time i were the first to say that i m ok and my sister lived in his town, but they never had time to meet themselves
happily he find a friend of him that comes to my city
i gave 10€ to him for the displacement to my home

i were very happy with the lens but no adapter to mount it on the 30D ,i were still waiting a M42-EOS (4-5 weeks for it) and i don t want to wait this zoo long time that i change the mount to M42 (irreversible)

whis 30D it was beautiful , very fine, but now i ve fuji XPRO-1 it flare and lost contrast badly even with a big hood
on the fuji the panagor 90/2.8 is better and extend to 1:1

i m gonna do more tests with it

Well, you were the recipient of a BARGAIN! Smile Very nice of the French person to give to you as a gift. I wonder if anyone
else on the forum might have a good guess as to why the 100/3.5 would be good on the EOS 30, and not so good on the
XPro-1? Does the body construction of the camera make a lot of difference? It seems that a lens would keep its own
characteristics no matter which body it was mounted upon. Shocked

By the way, NICE camera in the XPro-1. Cool

If a lens has a large image circle, it may have different performance on different bodies due to differences in baffling in the body.

Adapters have been known to cause loss of contrast, flat black paint will help.

I missed out on 2 of the 100/3.5's to go with my 55/2.8 macro.

Thanks for the information JC and Lightshow. I've learned a little bit about two possible reasons
why a particular lens will work differently on different digital cameras. This forum provides lots
of chance to learn something new.

Ive even heard there may be differences in the reflectivity of the sensors causing more flare in some situations.

Which was I think one of the root causes of early digital shooters saying old lenses are useless with digital cameras, but I think for the most part that myth has been put to bed.
