preset lens experience?

I picked up an old (60's) Sigma t-mount 135mm f/2.5 preset lens off of Ebay for $9 + shipping.

I couldn't find any info whatsoever about this specific lens. The closest I could find was of the f/2.8 version of the lens.

I mostly got it because of the massive amout of aperature blades that the preset lenses have.

I was wondering if anybody here had any photos that were taken with a preset lens.

Have a look at the Soviet lens club. Most of them are preset.

Take pictures of the lens & post them, often there's a similar lens with another brand name. And, if curious, join mflenses.com where the real experts live



For the price you paid you can't go too wrong, and as you say the bokeh ought to be great... these older lenses were designed in a way that modern, sharpness above all, across the entire frame, tastes just don't get...


Also, that reminds me: take a look here:

I have 3 presets

200mmf3.5 tak, 135mmF2.8Tele-Lentar and 105mmF2.8Vernon-Edonar.

I like the presets because in many cases the ease of use, you can meter at the shooting aperture in manual mode, have the lens wide open to focus, and then stop down easily to shoot with no risk of going past the preset. They also work in Av mode as any M42 lens does.

One thing to look for is the stiffness of the preset action vs a light touch of the stop down ring. I prefer this, and also look out for stop down rings that are too close to the focusing collar that you in-advertantly hit the focus and shift it when stopping down.

What I find with the presets, aside from more pleasing bokeh, which I suspect is a function not only of round apertures, but also the impression that at any aperture they seem to give better foreground vs background separation than later lens designs where the aperture is closer to the rear element.

BTW, I started the Definitely not the flat earth society to discuss presets and other lenses with round apertures.

Also check out the 135mm club, I did side by side comparison of the 135 tele lentar with an XR Rikenon 135 and a SMC Tak 135F3.5

One interesting side note on the side by side comparison, I found te XR Rikenon lens 1 stop slower (shutter speed at any aperture) than the tele lentar or takumar. Side by side comparisons are very interesting.

For 9 bucks you probably can't go wrong. My only experience with preset was with a Helios 40 (the silver one). Hated it. Not because of the lens itself but because I kept forgetting to stop the aperture down before taking the photo.

Heh heh, but that's f/2.3 and a rare item, the Komura.

Does the Sigma resemble this Vivitar?

Hrmmm... thought it said 2.5.

In any case, that vivitar looks newer. Here is the pic that the seller posted on Ebay.

For all I know it might not be a Sigma lens... but that is what the seller said it was.



edit: found what looks like the same lens but m42 mount. It is on the uk Ebay site and has the name "Photopia" on it.

I have four preset lenses and very much enjoy working with them. Three of the lenses are a Jupiter9 85 f2 in an M39 mount (slr lens) from 1964, a Jupiter 11A from 1974 and my favorite is a Takumar 135 3.5 from the early 1960's.

They are not highly coated and I try to use a hood as much as possible. The contrast is not as high as newer lenses. Part of the charm of using these older lenses.

The photos below were taken over the past few months in our backyard.

This is a shot from the Takumar.



This is a shot from the Jupiter 11A detailing the many aperture blades.

takumar 200F3.5

just to show the quality that you can get from these antiques

here is a shot using my takumar 200F3.5 on my K10D

note I use a split image focusing screen. I forget the aperture I shot this at.

Note you can see the liongitudinal CA as evidenced by the purple frinve in the OFF branches in front of the plane of focus, I prefer this to lateral CA where the OFF is green on one side and purple on the other

I love preset lenses. I like how they operate. Currently I have 4: A Takumar 135/3.5, Takumar 200/5.6, Macro-Takumar 50/4 and a Tele-Vivitar 85/1.8. The last lens was a T mount but I put a K mount on it. It is sharp stopped down, but crazy soft wide open with wild bokeh. Here's one example where I missed the focus:



It would have been a better shot stopped down, but I was practicing wide open. I do like the bokeh (swirly?). Post a shot with your lens when you get the chance!

This lens arrived this morning.

Here are pics of the lens. It has 12 blades.
It does have a couple big dust particles in it and the aperature ring is not catching most of the time. It kinda feels like there is a loose screw and this problem was mentioned by the Ebay seller.

Other than that, the lens looks to be in excellent shape.
