I'd be willing to bet just about anything that if these pictures were posted without any EXIF data, very few would be identifiable by lens. This is especially true of the more artistic shots, which I (and others, based on the comments) am drawn to.
Just out of interest, what you think is the more artistic shots (my guessing would be the close-up shots with special blurred background) ?
You're probably right with the focal length guessing. Many pics are cropped so there's no real chance to tell the focal length from a crop anyway.

That tells me that all of the Pentax 50s are relatively good and more than capable of taking good pictures, and that a good picture has a lot more to do with the photographer's eye than it does with the camera or the lens. Of course you know that already, but it's just what stood out for me looking at so many images of 50s.
I guess we are talking about separate topics, like - the photog + the lens + the cam (which is often validated as something like 70% + 20% + 10%). If in doubt it's always the photog missing out but hey this is a gear forum so I like talking those 20% also .-)


The LBA goat: Yashica ML 1.4/50 @f/1.4 on K100D. The horns are Pf'ing but still incredible detail at full open imo
Best, Georg

Are you sure this was at f/1.4? The detail is incredible indeed and the DOF looks a bit deep for f/1.4.

"Pf'ing".
You mean "PF" as in "ploody fringing".

I'm betting it is a crop, hence the somewhat deeper DOF, but I agree, it does look like a smaller aperture shot.

Thanks ClassA and Fixcinater for the heads-up,
I checked the whole series with the goat and reloaded the original unprocessed image (click on pic to go to full size)



I did tinker with the crop but I can't tell you no more what it was. In order to find out if it was stopped down I reviewed the whole series and the fastest shutter
was 1/250 like in this pic. It was 400ISO with all of them on a uniformly overcast day. Obviously I could have shot all those pics at say f/2, mmmh.
Please tell me if you think the DOF is still too large (for f/1.4) with the full crop.

I'll try to be more clear with my pics in the future,
Georg
PS: Found out that Picasa does only show 1600 pix max. online, so if you want the full file it is only via download from here
PPS: edit: I found a round specular highlight above the goat's right ear, looks like f/1.4

Nice processing to get the one you posted before.

Well, when you crop the DOF gets smaller so conversely your non-cropped image should show even larger DOF (may not be apparent due to different levels of sharpening).

Looking at the specular highlight in the crop, I think I can just about make out eight aperture blades.

But it isn't really a big deal for me. Very impressive performance anyhow.

Mmmphh.. how you know it's got 8 blades .-) Indeed the slight stop-down on this lens looks quite round.

I am sure about the full open - no pp- no crop with the same lens here,
https://www.pentaxforums.com/forums/751725-post72.html (second pic).

I think the faster the f-stop the more you run into the danger of overexposing - hitting the exposure at f/1.2
or f/1.4 is much more important for the outcome than stopped down. It's like having lesser latitude in
dynamic range. I've had this experience with very good lenses, too. They are more prone to reducing
IQ due to exposure errors, also at stopped-down levels.

Oh! I get it! You got a 44-2 with a Zenit-E. Does the body work?

It seems to, but I don't think the meter is working. I need to find the standard "How-To" on them to make sure we don't blow something up.

We've already got a Spotmatic, Spotmatic SP1000, Spotmatic F, two Canon DSLRs, a Canonet, a FED-3b rangefinder, Argus Super-75, and a Fostex-20.

There is a manual for the Zenith at Butkus's Zenith E free user manual, instruction manual
and another on the Krasnogorsky Zavod site Krasnogorsky zavod -- R&DC -- User Manuals -- ZENIT-E
and their parts references and the referring repair manual (see 6.6 re. exposure meter)

I think somebody rebuilt the meter with solar cells from a calculator.

I've never seen a darker viewfinder and a smaller mirror but the thing looks nice no doubt.

A couple of mine. And to think that I considered selling it a couple of months ago.
