Canon 25mm/F3.5 fit modern M body

<p>I finally got a Canon LTM 25mm/F3.5 for my screw mount Canons but I'd like to use it on my modern Leica Ms (M7, M9) too. I'm concerned about the depth the of the lens -- it intrudes quite a bit into the body. Has anyone mounted this lens (with appropriate LTM adapter, of course) on their modern Ms? Any issues? Thanks!</p>

<p>I use this tiny lens on my M4-p, and with adapter on my Fuji X-E1 without any problems - and it is a fine lens if yours is in good condition. Moderate contrast, neutral colors and only in backlight situations it is a bit prone to flare.<br>

As you have said - "it indrudes <strong>quite a bit</strong> into the body" ... not like old angulons or biogons. M7 and M9 user will confirm this information.</p>

<p>I use this lens regularly on my Leica MP with no problems at all. A nice, small, compact lens and optically very good, but with some flare, as Muller has stated.</p>

<p>Thanks for the comments! With Jim's positive experience, I (bravely!) attached the lens to my M7, then M9 and on the M9 took this picture. It's an overcast day so this is just a snap from my front door.</p><div></div>

<p>The lens is quite sharp considering it's age (according to PK, the lens is a Type I lens, manufactured prior to 1961). Here is a crop at full size.</p>

<p>I have had the 25 Canon for almost 40 years and have yet to see a Leica it will not work on. I have tried it on an M5 and used it on a CL. If it will work on those, and it did, then I see no reason not to use it on any other Leica. <br>

I now use it on my M8 for a very handy walk around lens if I want a little less contrast than the Zeiss 25mm.</p>

<p>I really love my Canon 25/3.5 LTM. I hope one day to have an M9 for it, but for now it does well on my Epson R-D1s:</p>

<p>The copy I used for this shot had lots of fine coating scratches on the front lens element, so it had an even greater tendency than normal to flare.<br>

BTW, I'd be interested if you could comment on the corner/edge performance of the lens on your M9, given it's deep rear element -- is there much color shift or resolution loss/smearing? (The R-D1 has a 1.5x crop sensor, so I'm not seeing the edges of the lens' image circle in my pictures.)</p>
