Tessar 2,8/45

Hi everyone! Uber-n00b here, Greets!

Look what I found rolling around in one of my camera boxes:







Anyone know anything about it? When I try to search for prices, reviews, or information all I get are thousands of hits to this very site and all to people's signature-lines. Hehe Smile

I could find out that it's 4 elements in 3 groups, min FD = 1m, it was designed in 1950 ??, and the manufacturer ID is "ZO" whatever/whoever that is.

Can anyone comment on the attributes (IQ) of this lens?

What was it originally designed for?

What are some of it's best uses? Portraits? Landscapes? Other?

What's the common name of this mount?

Is there and adaptor for that mount on Nikon? Canon? Sony? Oly? Panny GH1?

What does it typically sell for on e-bay? Although I don't wish to sell it - I love little MF treats like this! Very Happy

Awesome! That was quick! Thanks!

Do you know of any reviews on-line? Maybe with sample images and MTF plots, etc? I seriously couldn't find much on it. Is it rare or something? Also the sites I did find just had it listed in a massive table with other zeiss's - the date given for it was "1950 ~" as if it was still in production. Is it?

Sorry for asking so many questions all at once. Very Happy

And thanks for the welcome! Nice!

I found the spec. sheet! YAY!

http://www.zeiss.de/C12567A8003B8B6F/EmbedTitelIntern/Tessar2.8_45mm_e/$File/Tessar2.8_45mm_e.pdf

The spec sheet says 0.6 meters is the min. FD. Hmm...

I wish I would find something like that rolling around in my bag! Shocked

Welcome and congratulations to your great lens!

Thanks Lucus!

But I dunno how "great it is" These guys for example don't seem to like it much.

Quote:

45/2.8 Tessar - Agreeable mini-lens with non exceptional performance as usually thought, even if it is in any case high. Visible vignetting at full aperture. Despite its higher price, it is definitely less valid than the Planar 50/1.7 that, besides all, is 1 stop faster. Only useful for those who, combining it to an old 139 or 159 body or to the Contax Aria, wants a reflex that nearly fits in the pocket (but better at this point a compact like the Yashica T5 with the Tessar really breast pocket!).


I still reading and searching. And all I have right now to test it myself is either a Minolta A2 shooting straight-up thru it or a film camera. Razz It passes the finger test very nicely so maybe those guys are just full of it? <shrug>


Thanks for the welcome!

Yeah, I kinda think the link I quoted from above it's from someone who knows very little about this lens. The samples here are fantastic IMHO.

Hi there,

Thanks! Those images are a good reference!

Now I just have to learn the German language and I'll know what they're saying too! Very Happy

use the Google-translator, the results are "o.k.",
but short:

-not the sharpest lens, but still sharp
-typical Zeiss colors with a touch blue
-very very small and lightweight
-only for use 1.6/1.5 crop-dslr (hit the mirror of 1DMKxx and 5DMKxx)

Was really satisfied with mine.
Sold it as I have too many lenses around 50mm.

Sony and Nikon full frames should be fine, though.

Why are you guys saying like this? Is there distortion or CA in the outer regions of the image circle or something?

My finger test didn't show any but if it's slight it would be easy to miss.

As Kabraxis wrote above, the lens may physically hit the mirror on full frame Canon cameras (the same problem exists with many other lenses and FF Canons). It's no optical fault, just a mechanical one due to adapting the lens to a system it wasn't designed for.

but the lens is sharp straight from 2.8..

Ah, Thanks! How did I miss that text?? "(hit the mirror of 1DMKxx and 5DMKxx)" Weird, time for new glasses me thinks. Wink

Thanks and - wow those are awesome! And unless you have the best sharpening software on the planet I can't see it. I mean there's like no traces of sharpening in those images at all. And yet they are sharp as a tac - as if several levels of sharpening had been applied.

Just simply awesome!

That does beg the question of how they were processed tho. May I know?

Yeah, the samples I've seen indicate the same thing. But 2.8 seems to be it's only soft-spot. And even at that, the 2.8 samples I've seen aren't too shabby at all!.

Hi Tesselator ..

My camera settings have sharpness at ZERO level - I do sharpening in LightRoom but gently, of course ..

Tessar 2.8/45 is very sharp by itself with great colours -- images with this lens always look good and clear.

It works 'very good' with extension tubes - especially 13 mm.
