Hello,

I've seen a few references in various places that someone has converted a Super-Takumar (or variant) 55mm f2 to 55mm f1.8 by removing the aperture restriction. Have any of you done this, or know where I can find instructions about how to do it?

I had my S-T 55mm f2 partially disassembled to clean a hazy element (success!), but did not see where the restriction might be.

Meanwhile, here is a shot from this afternoon of a crocus with an accomodating fly (SMC-Takumar 55mm f1.8 @ f5.6, K100DS, ISO200).

This old thread might help. The info you need is about halfway down page 1: https://www.pentaxforums.com/forums/10-pentax-slr-lens-discussion/124763-supe...ml#post1290780

I bought my 55mm/2.0 with the intention of converting it, but then discovered that it had already been done.

Amazing !! wholeheartedly LIKED

Many thanks for this.


Feeling guilty about posting a photo by a Helios 44 earlier on this thread, here is the real deal. The Auto-Takumar 35/2.3 and the Super Takumar 35/3.5, taken by a Macro Takumar 50/4 preset. Three of the great Takumar lenses.

Now that is utterly, entirely and deliciously photo-pornographic.

Hi - I have a dumb question to all my fellow Tak users...


When you use your Tak's on DSLR's, how do most of you deal with the adapters? Maybe if there is enough interest, we could do one of those Forum Surveys...


Do you:


1) Have a dedicated M42 body and you leave the M42 to K adapter in that body, and screw lenses in and out
2) Have 1 M42 adapter per lens, and disable the spring lock
3) Have 1 M42 adapter, but switch back and forth on your every day DSLR body to modern lenses.
4) What is an M42 adapter?


The reason I'm asking these questions, is multi fold.


1) long heavy lenses are a royal pain to screw in and out, like my 300mm... I find it easier to have 1 adapter per lens on the small lenses, but on the 300mm, it scares the heck out of me to not have it locked.
2) I noticed wear and tear, even on my good Pentax brand mounts
3) I noticed on my cheap knock off mounts that metal is flaking off the adapter, and I sure don't want that in my DSLR!!!!
4) there is enough slop in the mount when the lock is removed to effect focus, etc.
5) because inquiring minds want to know!


Thanks in advance for any and all replies,
Eric

Not dumb...but slightly scary!

Personally, I only have one adapter, a genuine M42 Pentax one. I switch back and forth on my Pentax DSLR body to modern lenses, without major hassle, and no focusing/hit mirror issues (as some other camera brands experience with some M42 lenses), and without disabling the spring lock.

I agree long heavy lenses are more of a pita, but not insurmountable (to use a pun). The only lens I ever have an issue with is the Helios 44-2, because, as others also report, it "wobbles" a bit on the adapter.

Haven't noticed much wear and tear on my mounts, and that's a scary question about flaking metal. I also successfully use a M39 to M42 metal adapter, not a genuine Pentax, and followed someone's advice to "brush off any flakes" on the new adapter with a strong piece of cardboard! The idea of using a separate adapter for each M42/M39 lens...would be quite expensive for me, and unnecessary.

I don't think people should be put off trying screw-mount lenses by the potential adapter issues you raise.

Having said that, I do know someone who won't even change his modern lenses outside, in case dust etc. gets into his camera...and he changes lenses indoors holding his camera (a FF Canon) so the camera mount faces the floor!.....But then, he's a rather careful person, and also owns Hasselblads and Leica's, and the only lens I have that he grudgingly acknowledges is an 8 element Super-Takumar 50/1.4.

why grudgingly - what is wrong with it ?

[wtlwdwgn]

Yep, best to have a genuine Pentax M42 adapter. You won't have any problem switching between M42s and PKs. Mount the adapter first and then the M42 lens. Just my ¢¢.

[tim60]

I only use Takumars, so the genuine adapter sits in my camera continually.


I have a couple of genuine adapters, with springs, but one has the spring out of adjustment and occasionally it comes off with the lens - a real pain to get off. The other one is working correctly.

here is some more with s.tak 28/3.5

[Bob Conrad]

This is the lens that focuses 1:1 in the 35mm format, even closer on my K-500.

It has gone up a bit now. A year ago I got my 85/1.9 STak for what I then believed to be a good price of USD213.39. Usually the SMC and S versions go for about the same. Prices do vary wildly. Mine was a BIN eBay but bare lens, no extras. Could go as high as 300-350 if the seller is offering to all countries.

Option 3, original M42 adapter.

When you use your Tak's on DSLR's, how do most of you deal with the adapters?

I keep a cheap adapter semi-permanently attached to each Takumar with a tiny dab of the lowest strength Loctite (with the clip on the adapter removed, of course). I can understand why collectors would prefer to leave their Taks as native screw mounts, but personally I think of my lenses as day-to-day shooters, and life out on Dartmoor is a lot quicker and easier with them adapted to K mount.

On a side note, because I'm not a collector I've saved a lot of money in auctions by buying cosmetically grungy examples that nobody else seemed to want. A couple of scratches on the front element is no big deal, and the only thing that will scare me off a lens is serious fungus.
