Mamiya 7ii lens changes

[tom_westbrook]

I posted this to the www.mamiya.com user forum, but wanted to try for

some [relatively] unbiased opinions here:

 

I just got a M7ii with 43mm & 80mm lenses to supplement my old RB Pro-

S outfit and noticed a warning in the M7ii manual (pg.13) about not

touching the coupling roller with the lens when inserting it (esp.

the wide lenses). The 43mm almost touches the roller even if you have

it shoved all the way over on the other side of the lens opening

(it's a pretty tight fit).

 

How much should I worry about this? Has anyone knocked things out of

alignment by rollong the roller when installing a wide angle lens?

The 43mm is a tight fit, but I'm just a little more gentle when I take it on or off. I take it on or off a lot and so far no problems.

 

Congrats on your new gear.

My guess is the manual writers were overly cautious. As long as you put the lens in straight the chance of getting the roller caught by the rear barrel are minimal. And even then it should take quite some force to bend the roller arm. Just pushing it doesn�t do any harm to the range finder alignment. That�s the way this thing works (simply put). By rotating the helicoid in the lens you�re pushing the roller in and out. This moves a prism inside the rangefinder with builds one part of the double image in the viewfinder.

Thanks for all the reassuring replies. This is my first rangefinder, so the little oddities are a bit nerve-racking. I love this camera, though.

Hi,

 

That's the same equipement I use (M7ii with 43mm & 80mm) for 3 years. I've never had any problems, but, I think I have to tell you, that the 43 mm is my favorite lense, I don't change every two minutes...

Kind regards
