Just traded for a Rokkor 58mm f1.2 lens and looking forward to giving it a workout.

Anyone have a source for filters for the 57mm thread on the lens? I checked B&H and Adorama and did not see anything available. Was thinking a PL and a ND would be good to have for this lens.

Thanks,

Shawn


filter thread is 55mm not 57mm.

Are you sure? Lens cap says 57mm and a 58mm filter is just barely larger than the lens threads.

yes, i'm sure. i presume you have the metal push on cap that goes over the outside of the lens rather than in the threads, thus it is 57mm rather than the diameter of the filter threads (which is 55mm for all versions of the lens).

It is a plastic push on cap that also has a ridge for the inside of the filter threads. It isn't a pinch cap though. 55mm would be a lot easier, I'll pick one up, thanks.

Any threads on cleaning dust out of the lens? Optics look good but it is a little dusty.

Thanks,

Shawn

usually the dust in these lenses is just on the glass around the aperture. if you follow the instructions in this video to the point of removing the rear optical block it'll get you to the point where you can clean the two glass surfaces that face the aperture.

Thanks, looks easy. The biggest piece of dust (dead center) is to the rear of the aperture so it looks like that procedure will let me get it out of there.

Couple of shots from today with the 58mm.

Sebboh,

Thanks for the link to your movie. Just took my 58mm apart and used a rocket air blower to get the dust out. Looks like the vast majority of the dust is gone now. The entire process took maybe 10 minutes.

Derek, nice beach shots with the 28/2!
I just posted some RX1 shots from same beach.
Looks like it was sunnier the day you went.
Haven't had time to do the 28/2 comparison yet.
How do you like it?

it was shockingly sunny and warm when we were at the beach, i was almost tempted to go in the water.

i'm kinda torn about the 28/2. on one hand it has produced a shockingly high percentage of my favorite shots considering how infrequently i shoot with it. on the other hand, it is giant on my camera, not as sharp as my g28, and my copy has some optical issues that i know effect it's performance but i'm not sure to what degree.

a pic with it at f/5.6 i think:

another shot from the mc pg 50/1.4:



after processing it i realized it's kind of a homage to paul's old shot:
http://www.fredmiranda.com/forum/topic/1174892/0#11199901

though his is more impressive and captured at a better time of year.
