G Zuiko 42mm f1.7 35SP adapted to M mount

Did I post this on the wrong forum?

Oh wait....it does have a M mount right?



my fingers are all tore up and I spent all of the evening on getting this lens unit out. but infinity checks out on my XE1 with hawk helicoid adapter. Also, the aperture works perfectly!

f1.7-f22(unofficially)

It can also be adapted to be focused on a rangefinder but will need more surgery. Probably I will do that in the future so it will match up with my M's RF cam.

enjoy some lens pron!

thanks! it came from a donor camera that was grimy and gritty feeling. the oly 35 sp also had problems with the shutter speeds and sometimes it didn't fire up at all. it finally gave up the ghost recently and I thought "why not?''

RIP:


sample pics up next.

at f1.7, closest focusing distance around 0.35m

f5.6 (i believe)

at f1.7

at f8


more pics can be found here at my blog:

I used my hawk's adapter to get even closer. the closest I could get (guesstimating) is around 0.35m. Without the adapter+XE1 and on my Leica it goes roughly to 0.7m~0.85m according to it's scale on the lens. it matches up what I am seeing from liveview as well.

Very cool!

I love that lens on my 35SP - now even more.

Adapting Lenses

Anyone on the forum familiar with small contrast sensors used to sense focus?

Insane genius! I love that lens. But I do love my SP. Now, if an SP could be adapted to take M lenses (one of which was the G Zuiko 42/1.7), I'd be over the moon.

epoxy cementing worked with tons of careful measurements.

i took the lens with me with my xe1 on a camping trip recently and had some fun shooting it at all apertures.

to make it more usable, i coloured in the mounting point, and also moved the focusing tab to the aperture ring so it doubles both as a focusing aid and also a way to easily change the aperture. (the whole front unit rotates when focusing so polarizers and other filters will not work well.) also, in a stroke of inspiration, i used the metal timer tab to act as a infinity stop because it rotated past the DOF markings. cutting away at the DOF marking ring to create a stop was fairly easy (again making careful measurements)



the lens matches well with the hawk's adapter: (and the almost pancake dimensions of the lens. the lens looks like it definitely belongs on the xe1.)
