Using the 50/2.8 with the M85

In the M8 user manual, there's a warning about using collapsible lenses but it says the 90/4 is OK. I'm wondering what the issue is then with the 50/2.8, the lens that breaks the rule of Elmars being f4.

 

I'm slightly disappointed as I had it in mind to build a set of the 28/2.8, 35/2, 50/2.8 and 90/4 as an ultra compact travel set which offers more speed than the Tri-Elmar but I would not want that sinking feeing as I collapsed it without thinking, the lens pressing the shutter back into the sensor, bending the shutter and cracking the sensor cover plate.

 

Does anyone have a picture of the 50/2.8 collapsed? How far back does it extend?

 

[bTW, the M85 is not some secret follow on, it's the product of my inability to type]

Mark,

It sticks out rather far. I found this shot on popflash.com (hope Tony forgives the repost). A solution offered by a guy on pnet is to find an o-ring that makes the mount stop before it gets to the shutter. He'd done this for his for use on the RD-1.

 

I really like this little lens.

The 50/F2.8 is a sweet lens but by the time you've screwed the little hood into place it isn't a great deal more compact than the 50/F2 (which is a very useful stop faster). I ended up selling mine for this reason.

 

That's a good point, Ian. The 50/2 is hardly bulky...

The current Elmar 50/2.8 has a somewhat unique character, difficult to explain without trying it.

As contrasty as other modern M lenses, very sharp without being clinical, very little flare and a smooth bokeh (f/5.6 in the flower pic below).

I protect it with a mere shoelace on the R-D1, so that it may protrude into the body without touching anything.

No problem at all.

The new CV Heliar 50/2 collapsible barely protrudes at all when in its stowed position. I'm eager to try it on my M8 (whenever that might be.) I can't imagine it would interfere with the shutter or sensor given the slightly raised M-mount on the M8 photos that I have seen.

 

I'll report back what I learn on this topic.
