A killer price for a killer lens.

This lens also covers full-frame, so that little coating issue is pretty safe from ever showing up on an APS-C sensor.

My M42->PK adapter just arrived today (after three weeks...), so I can finally get to using my Helios 44-2! Went out and took a few test shots already, and I'm liking it thus far. Worth the hassle of finding one on ebay for a decent price.

It worked!



Here's showing how I overlapped them to make it work. I just left all four pins on each, doesn't seem to make any difference and it helps to keep them in line.

Oh, that's a good idea! I'll definitely try that. One's held in with plastic welds, so I'm going to have to be super careful getting it off to use, but stacking may work. I'll report back in a bit.

Welp, bad news :( The lens I purchased, a FA 35-80mm, only has the 4 pin versions of the contacts, not the 5 pin one. Dunno what I'm going to do now, I guess try to figure out a way to hold a 4 pin one in and hope it works.

Well I'll find out! From my research it seems there are only two versions,a5 pin one anda four pin one. Even if the lens i picked up only has the four pin one, I may be able to make it work as it seems only the three middle ones are used.

Do you have the piece to fix it or something?

Well since I've not put it back together yet, I looked for any access doors but can't find any. I think the DA 35mm is just too small for one to be feasible. The time this brush is made available for removal is right when it's very easy to damage it, heh.

Glad to hear zooms have two! I just went ahead and ordered an as-is 35-80mm FA zoom to scavenge from ($6 before shipping) just in case straightening it doesn't work. I love this lens, no way I'm going to let a little error on my part take it out of commission.

Ah, that's the piece exactly! Once I get a hold of a pair of tweezers later on, I'll give it a shot at straightening it. Otherwise I could try hunting down some wire like his, but I don't think I have anything this small. Pictures are incredibly deceiving, these pins are <= 1mm in width.

Worst case scenario, I could just try to find an as-is F lens and salvage it from that, since it seems to be a common part in all of the autofocus lenses.

That's what it looked like to me too, but I was confused because... this is a prime. I'm putting it back together now but I have a class in 15 minutes, so I'll respond with whether or not AF works after that.

Sorry if this is the wrong place, didn't see anywhere better though.

So I was working on my DA 35mm f/2.4 because a couple of months ago, it got blown out of my bag (helicopters are neat) and thrown through the dirt. Since then, I'd noticed some grinding in the focusing mechanism, and since it was bought secondhand, I decided I would clean it out myself.

Since it didn't have a lens disassembly post already, I planned on doing that too so I went a little further than I needed to. All was well until I started putting it back together and learned just how tight some tolerances are.


This is the piece that got mangled during reassembly for being a fraction of a millimeter off-center. Fun, right? I was wondering if anyone knew what this little thing was called, so I could hunt down a replacement somehow. Buying a new lens isn't an option, as I'm a poor college student.

All help would be greatly appreciated, thanks!

Thanks! I went through, and this is the most decent "close up" I could find. I don't really have any lenses that focus close up and with how active they were, it was hard to find one that would stay still long enough to get close.

I didn't notice while I was taking the picture, but this one's got sizable pieces missing from both of its wings. Was still flying around though!

I just got a chance to finally test my AA-holder with the Eneloops I ordered, and the first thing that I noticed is that autofocus is noticeably slower when using the Eneloops. Is this just something that happens with them, or is something wrong?

Not airplanes but a helicopter, a UH60 Blackhawk (actually two different ones) that were with my school's ROTC performing an air movement.

This last one is interesting. I may have not extended the hood on my lens, but for some reason the colors were very... off, and can't seem to be recovered. I kinda like the look, makes it seem a bit "vintage".

Strange Shadow problem in Lightroom

Hey all! Sorry it took me a bit to reply.

I shoot in RAW only, so this is from the RAWs themselves.

Rawr, from what you've posted, it sounds like posterization should appear only in the library module? However, this is appearing in both the library and develop module.

It would make sense that Lightroom is taking some shortcuts on rendering though, especially considering that my computer is, for lack of a better word, absolute crap.

Strange Shadow problem in Lightroom

So pretty much, in Lightroom, shadows appear "blotchy", but upon export (or on other people's computers, they appear fine. It's a bit hard to explain, so here are examples:

Lightroom:


Export:


As you can see, that's a massive difference. Does anyone have an idea as to what's caused this?
