44M aperture/aperture pin issues

It's alright - no worries!

I've put the lens back together, balls back in place, everything is fixed (except the M/A switch, I couldn't be bothered to put the washer underneath it, too difficult).. Turns out it was just a bent aperture pin. I don't really know how to fix this, with the back of the lens off I can pull it out but it still gets stuck back in, you can see that it's quite bent.. I mean not overly but there is a slight shift in direction. Any ideas to get it straight?

It's done, I used some pliers and bent it slightly.. AT LAST.

Thanks for all the help everyone!

Sigh I spoke too soon- the lens won't screw onto the camera anymore. If the pin is out it doesn't screw on no matter if the lens is set to M or A, whether the shutter is locked or whatever setting is changed. If I push the pin in and it stays in, i can screw it on, then the pin unclicks once on the camera if I take a shot or two/change auto manual and the aperture. But then I can't unscrew the lens.. Arghh

OK - I fixed the pin I think.. Had to bend it with pliers, I should've read that part before taking the back off. I can't figure out where this little ball goes, if I screw the M/A switch on without it it's limp and doesn't hold..

well i've taken the back plate off. I accidentally unscrewed the screw that held the manual/A switcher in place and a tiny little ball fell out.. You wouldn't happen to know where it goes back?

I can't budge the pin.. It's weird. here are a few pictures.

Here's the little ball

When I turn the ring in A mode, the blades start to close at 5.6 and continue to do so. In manual they just close from 2.
Also, as I said, pin is stuck in both A and M modes

I'm actually using it on my spotmatic F. I assumed it worked like the other m42 lenses I own and is able to be used in auto mode to allow for stop down metering. Maybe I'm wrong and the 44M can't be used in this way?
any explanation for why when I turn to say f5.6 the blades are still at f2, and at f8 they're at say f4?

I'm just going by how my other lenses function.. It could be different, but I can't understand why the aperture pin would be jammed.

I recently purchased a 44M and seem to be having a couple of issues. Firstly, the aperture pin doesn't seem to budge. It looks as though it's half pressed in, and it wont budge at all. Is there any way to fix this?
Secondly, when I turn the aperture ring on the lens in auto mode, the aperture that the ring is set to doesn't match the aperture the lens is showing. So if I turn to f4, the lens is still wide open. It only starts to close around 5.6, but when you get to 16, and then switch to manual at 16, the hole is significantly smaller. Is this normal, and could it have anything to do with the pin being jammed?

Both these problems can be ignored by shooting in manual mode, but it is nice to be able to use the lens in auto mode.

Helios 44M-4 vs 44M

Wow fantastic swirly bokeh on those two photos!
I guess I might pick up both a 44-2 and a 44M. If I get a 44-2 that doesn't swirly I'll just throw down the money for another one! Does the 44M require aperture pin modification to use it on an DSLR?

Thanks a lot Steve, that seemed really helpful.

Did you think one shined over the other in terms of 44M and 44M-4?

Maybe I'll just stick with a 44-2, and if I get a copy that isn't so swirly just purchase another one, they're relatively cheap these days anyway.

I guess perhaps much of it depends on the manufacturer of the lens.

What about with the helios 44-2s? I know there are various manufacturers, and while I don't know the names of each, I have seen different symbols on the front of the lens. Does anyone have more than one helios 44-2, or has compared various models to know if there is a difference?

Well there doesn't seem to be a clear one way view on this issue.
I don't mind having to modify it to use on my DSLR, so that doesn't really put the 44M-4 out of the running.

I've read that the 44M-4 is newer and most likely multicoated, however won't produce as much swirl as the 44M. Is this true?

Thanks.

I do plan to use it on a DSLR as well as the SP. if I modify the pin will this have any effect on using it with the SP?

Also, I assume more blades = better bokeh?

Can anyone comment on the 'swirly' bokeh effect of any of the lenses mentioned?

Thanks for that. Why was the lens designed that way, or is it only on spotmatics that this fix needs to be done?

Is modifying the pin optional? How come I have to modify it?

Hi everyone,

I recently purchased a spotmatic, and while loving my SMC takumar, I'm fascinated by the bokeh that the Helios lenses can produce. I'm absolutely set on a Helios 44-2, I love the swirl that it can create. However, since I live in Australia, and these lenses are rarely available here, postage makes the price a little bit steep. I've been offered a deal of combining postage with a 44M-4 or 44M, and i'm not sure which one I should go for.

Is one clearly better than the other, or are they any major differences? I guess the thing I'm looking for most is the swirly bokeh, so does anyone know if one of these does it better than the other?

Thanks a lot guys!
