Helios 44m-5 is good for k10d?

platinum · 01-14-2009, 12:23 PM

i 'm finding info about "Helios 44m-5" (russian lens m42)

this lens has NOT auto\man switch, i know.

so, this lens is a "preset"???

please, can you give me more info if can i use a Helios 44m-5 in AV mode without limits (Aperture Priority), similar to a jupiter-9 ?

or i can use in AV mode only in wide open?

see here 2 images

(here there is a "pin")

If it does NOT have a manual switch, it will stay wide open if the pin in not depressed.

Since our bodies do not depress the pin (unfortunately), it will stay wide open.

I believe the 44-M 6 has a manual switch? Otherwise, you'll have to use the preset 44-2.

There's a few posts around here somewhere (check the russian lens club) that show you how to remove the pin so the lens can work in Av mode.

Yes, you can remove the pin or shim it from the back (requires partial disassembly) to convert the lens to fully manual diaphragm.

This is a replay from the other thread,
"About the manual aperture conversion, just unscrew the screws on the back, hold the pin from outside while lifting the back off, put a piece of a cotton swab plastic shaft onto the pin from inside, close it back. There you have your manual lens (done that on version -6 and -7)."

platinum,
your lens looks nice, hope you get along with the conversion. You end up with a 'manual' lens, so you'd have to click click click stop down to your chosen aperture after focussing full open (counting spares you the looking on the scale). Otherwise, you leave it stopped down and just focus and shoot in AV-mode. This depends on the amount of light and the f-stop obviously.

It's quite easy actually, just make sure that no screws or the aperture pin would drop inside the lens while tinkering,
Georg (the other)

PS: A 'preset' lens is an earlier generation lens, where you can preset the aperture and then just fully open and close to the preset value with a separate ring (and no click click click)

If you are lucky you may be able to find one of these little gems. It has a rear flange which depresses the aperture stopdown pin on M42 lenses when they are screwed onto the adapter, stopping them down to whatever aperture they are set at. I was very lucky to get one from China through the kind agency of a friend.

This adapter is the perfect solution to using M42 lenses without an auto/manual switch. It is very well made and fits into a K-mount body even better than the original Pentax adapter IMO, but it can still be removed with a fingernail.

Regards, Jim

Jim, I don't suppose you have a picture of this adapter, do you?

I guess this is the one Asahiflex adverted for on a Dutch forum. It sounds good. As for the question of the OP: yes, you use this Helios without any restriction if you do the mod on the pin as described by the other Georg. Somewhere in the catacombes of this forum you will find pictures on this mod too!

Hey Jim, that adapter does sound very interesting, any more info would be much appreciated.
