I recently picked up a Vivitar Series 1 28-90mm made by Komine. The word is it's a very sharp lens. So I put it to the test with the sharpest lens in my stable, the CZJ Biotar 58mm f/2.0. Nothing serious or scientific, just trying to compare as best I could for the fun of it. I adjusted the zoom on the S1 to approximate the focal length of the CZJ. All shots were at f/5.6 on a tripod, shot raw with no pp and exported to JPEG in LR4.

Now, guess which of the two lenses captured this one and you could win a cheeseburger dinner at my place cooked on my grill! (Airfare and taxes extra, of course!)

Interesting comparison -
to my eye they are virtually indistinguishable.
Thanks for the fun

I am guessing that the last shot is the Vivitar as I am sure the Biotar has more than 6 blades. _________________ Lots of 35mm Film Cameras

Like I said in a previous post. In my opinion there are three qualities of lenses.
A: low quality where you get an acceptable image but soft and not quite sharp
B: The majority of camera manufacturers lenses and named indie brands
C: The ultimate expensive Leitz's and Zeisses
Both these fall firmly in cat B unsurprisingly. _________________ Hero in the 'messin-with-cameras-for-the-hell-of-it department'. Official. |

Well ignoring contax lenses and similar....the results don't surprise me as even a very good old zoom at its sweet spot stopped down can look the same as a good prime esp on a computer screen, I proved this to my self many times and it needs a large print or crops to show the difference....of course the differences might show up more with shots of buildings for distortion. _________________ Canon A1, AV1, T70 & T90, EOS 300 and EOS300v, Chinon CE and CP-7M.

I have always thought it to be a little arrogant to deny Vivitar (or Soligor lenses, just to name two) any capabilities, just because they do not bear a well-respected name.
There are some real gems amidst those. _________________ Personal forum activity on pause every now and again (due to job obligations)!

I played with known 3rd party manufacturers from Japan (+Korea) and put them into average brand quality & trust categories. Just for fun, there are many exceptions of course. Also remember some brands were reselling others. Please don't take this list to seriously. It would also vary according to production years used (Samyang quality for instance is now much better then 20 years ago):
1st category: Kiron, Komine, Tamron
2nd category: Kobori, Tokina, Cimko
3rd category: SUN, Cosina, Sigma
4th category: Samyang, Makinon, Ozone, Osawa

I had only one lens with osawa brand, and it was quite good. So i gave it a vote on facebook - guess it will be the only one.
The problem with that is that I don't remember which lens it was. A 200/4 maybe? well, who cares.
Also, Cosina made lenses that could fit any of the categories, probably. _________________ C&C and editing of my pics are always welcome

Good point. When I view shot #2 at 1:1 resolution it's obvious the Zeiss picks up amazing little details the Vivitar misses completely. I'll post examples later to show this. |

A couple crops to show the comparative details. Biotar shows off its crispness at this view level -- even with me driving it.
