Mamiya Sekor SX 1.4/50 on K100D @f2(?) ISO800 1/15 handheld no pp daylight jpeg all neutral crop only

I have just obtained a Komura 85mm f/1.4 (complete with the original hood and case). The lens does have issues with PF in high-contrast situations, so I have to be very cautious when using it wide open

It looks like this:

And wide open it delivers results like this:

In case you guys missed this thread

I am putting an M42 kit together, what is the best 135 outside of the takuamrs?

I would appreciate posts in the other thread but I will keep an eye open here also

I just recently acquired a Vivitar 35mm 1.9 & Auto Mamiya Sekor SX 21mm 4.0. These are my first M42s and I am awaiting an adapter to try the on my K20D. From reading here I understand I may not want to try the Mamiya without modifications.

Anyone here experienced with either of these?

Those are very nice and rare lenses you got. I'm very curious on the performance of the MSX 21mm f4. Quick post some examples soon

I also reckon it would perform wonderfully on a 35mm SLR.

That Mamiya 21mm is a good find!

**ramseybuckeye** · 01-14-2010, 09:32 PM

I did get a few shots with the Mamiya 21 with a Spotmatic that came with the lens. This is from the only roll of film I've run though it, there is a light line running horizontal across the upper third of each photo, probably from the camera, but could have been processing (had them done at a Meijer store and put on a CD).

Mechan1k · 01-15-2010, 03:54 AM

I'll be adding an M42 Tamron lens to my collection .... that's what it was advertised as I know.
Will find out when i get it.

it's a 400mm f/6.3 that I picked up relatively cheaply ... so will be testing it out (maybe with a TC as well just for fun)

Steinback · 01-15-2010, 04:26 AM

If you have a decent amount of light then a 400mm f/6.3 will work alright with a 2x converter. I posted a handheld sample from my cheap 400 and $5 converter all the way back on page 1. If your combo works we could do a budget 800mm shootout with stop signs, pop cans, or some other common item found at opposite ends of the earth to see who has the more desirable aluminum baseball bat/lens.

Mechan1k · 01-15-2010, 04:40 AM

I have been doing a bit more reading about the lens ... and it seems it is a T-mount by the looks of this ... if it is ... I'll just get myself a converter for it ... either a K-to-T-mount .... to M42-to-T-mount.

I'll be using it only in decent light ... or maybe the odd moon shot if i can get a chance.

Seems like the lens retain details rather well!
Will need to note however, for wide-angle lens, you need to be very careful on horizon tilting.

Tamron had a t-mount in 200mm with f6.3 and two 400mm lenses at f6.9 but I don't recall a 400 at f6.3. They even had a 400 at f5.6 as well as one f7.5 and one f8.

They had a F system but I know squat about it. As far as I know, they had nothing in 400mm in adapt-a-matic.

Mechan1k · 01-15-2010, 09:51 AM

I know ... it is weird.
Unless the seller wrote it down wrong .. who knows.

Although there are a number of other 400mm f/6.3 lenses out there that apparently were made by Tamron and just badged for those companies.

I have been going a hell of a lot of reading ... and found those links above you posted as well.
I guess I'll find out when i receive the lens ... I have been speaking to the seller and he said the lens is in very good condtion with clear/clean elements.

Better than what I have read regarding similar lenses with the rear element is either cloudy or has some fungus on it.

I am suspecting T-mount though as it does look like an M42 mount ... and it looks rather similar to the off-brand 400mm f/6.3's as well. I am hoping it may be an f/5.6 though.

Who knows ... it was pretty cheap as it was.

I guess we all find out when i receive it and take shots of it.

PS: There was one mention in a blog somewhere that there was a "Tamron Popular" f/6.3 version ... but no pics of it.

I recall reading about a Tammy f6.3 on mflenses.com but no one had actually seen it IIRC. That f5.6 version is a very attractive lens.

There maybe a possibility that Tamron made some bona fide m42 lenses in the late 50s early 60s since so many companies were using that mount.

Mechan1k · 01-15-2010, 10:37 AM

I have a spare K-M42 adaptor anyway ... I'll test gently with it first before i do anything.

Hey if it's the f/5.6 version ... I'd be over the moon .. especially for what i paid for it.

It has been posted already ... so it is on its way (from within Australia as well) ... so i should get a note in the mail soon to pick it up from the Post Office.
