Thanks.
No not hardcore. Just simple pleasure ;-)

As for Peter's photo, I just compare my photos from the K85f1.8 (I do have the M85f2, but have not a photo of similar scene). The angles and bokeh are similar, but measuring the size of the boat, it has to be wider than 85. Wide open? That implies relatively 'slower' than f1.4, may be somewhere at f2.

My best guess is around 50f2, not likely you have owned this cheap lens, but perhaps one of the classic 55, and somewhere around f1.7/1.8/1.9. You won't shoot wide open if the lens is not sharp wide open, maybe therefore in BW. So which lens in ~50 between f1.7-f2 sharp wide open?

I had nothing beyond I thought it looked like a leica, but couldn't figure a focal length, maybe a 60?

This will give it away (at least the focal length)!

Thanks. Also confirm the flute photo.
It looks like 12mm, 14mm, 15mm, 16mm. My best guess is your samyang 14 manual focus, not from your da*16-50. I have 8-16, 12-24, 15 and can verify this ;-)
Looks more like my 15 than 12.

didn't look wide enough to me for the Samyang, but on reflection you are probably right (didn't look at daniel's profile for lenses. I should have

still longer, and I never owned 35mm lens

I'd say the M85 f2.
I had that one, but not for this shot.
The used lens was shorter

I'll give this one away now:

Why do you think it's slower than f1.4

Close enough! It's my newly acquired K15/3.5 early version.

Not bad wide open at ISO500 (100% crop):



in comparison this is from the Samyang at f7.1 and ISO320:

Cool. I have the Takumar version, M42. I should trust my instinct ;-)

One can't be wrong if it is shoot at f1.2. At f1.4 it is still blurred to unrecognizable.
Your photo has a human being 2x boat distance, I guess he/she is about 16-20 meters from the camera, and therefore it has to be slower than f1.4.

I might be wrong if the boat length is shorter, as I haven't seen these boats in London. 'Normal' marine vessel length is about 30 feet (10m).

So what's the correct answer?

Gents,
Agreed, this was a tough one. Ok, rabbit's out:




the lens: Tokina AT-X AF270
the EU roots: Angenieux, France
the corporation: Thales
the famous and/or relatively well-known brothers and sisters: Angenieux and Tokina AT-X 28-70/2.6-2.8, Tokina AT-X 270PRO, Tokina AT-X 270SV, Tokina AT-X 280PRO

That shot was taken at 70/3.2 setting in a point-and-shoot way - to be honest I was really surprised it turned out any good at all, I had no time for scene adjustments nor any other stuff to twist and set.

Zig

P.S.
I'd say that if it were some Voigtlander the colors would be more punchy.

I WAS ABOUT TO CALL OUT ANGENIEUX! Followed closely by Alpa, Naturlich.
Angenieux is/was a superb manufacturer, we all owe them a debt for making wide angle on an SLR tenable.

It's SMC 1:1.2 50mm wide open!

Hi Siegfried, I got this exact lens only this week. (as well as an FA43, it's been a good week ) I thought it would make a good alternative to my sigma 17-70 as a walk around lens. What are your thoughts about it? The info you provide is more than anything I could find about the lens. Thanks for that.

Gents,
Good evening. Sorry I missed lots of pages of this thread - I've been busy with Matt Damon I've been working on some other projects of mine.

axl,
it gonna be a wild guess, but it must be some M42 fifty a couple of stops stopped down.
Edit: Douh... Probably I need to work on my typing to make it faster a bit.


Daniel,
I was going to say '21st lim' but after you lately mentioned some really wide apertures I have to twist the steering towards to... I donno, some Sigma? these boys love when it comes out black, big and fast.

wizofoz,
Pls gimme a break, I need some time to spend learning your name - there're too many Zzz'z even for me who starded hiz English wiz 'yez, it iz'
Feel free to PM me (to keep this thread clean) all the questions you've got on that lens and I'll get back with review published in PF lens reviews, Tokina group.

Zig

N.B.
Dear gentlemen (and ladies, should you finally jump in sooner or later - you're very welcome), shouldn't we work out some rules on keeping this ball rollin? I'll be glad to see this excellent thread being clean of other stuff - whenever it turns out to be interesting or not that much - and it'll be also very nice to avoid those collisions e.g. the one happened between axl and Daniel. Die Ordnung ist die Ordnung as they say in der Vaterland of Leitz und Zeiss.

Du hast recht, Siegfried!

Also it is interesting that people thought the K15/3.5 was a Leica. I think there are some similarities in rendition, that's why I was hinting at German engineering - the K15/3.5 early version was reputedly a Zeiss design. And 30 years on it seems to walk all over much the larger Samyang in the comparison above.

Samyang though should be much more resistant to flare and CA I expect (I only just got 15/3.5 and it's been very cloudy).

PS Eddie was very close with a Zeiss 20/2.8 guess. Did you think Zeiss from the pics or from my hints? Do you recognize Zeiss rendering?

Dan,
I think these are just too much different engineering schools between Asahi-Pentax (and probably Zeiss as well) vs Samyang. Just count those groups and elements they use in their products.


Well,
I'm typing as fast as I only can to jump in with this la Arlecchino shot. Obviously it'd be easy to guess, but let's keep it rolling (and sometimes funny).



Yours,
Zig
