Disappointed in image quality.

I got a Kalimar 35-70/3.5 just prior to going on vacation & ended up using it most of the time because the focal range seemed right most of the time. However when we got home I was disappointed with the image quality when viewed on the computer. I decided that I would like a similar lens with better IQ & had a look on the net to see what I could find. I discovered a camera shop in Toronto selling off new old stock that had been purchased from another store closing up & I made the trip to check it out. I took my camera & the Kalimar lens with me so I could do comparative shots.

I tested the Kalimar against a Vivitar 28-85/3.5-4.5 & a Soligor 35-70/3.5-4.5, shooting all three @ 70mm FL & f3.5 (wide open).

1. Kalimar




2. Vivitar




3. Soligor




I was expecting the Vivitar to be best but it had poorer IQ than the Kalimar. I bought the Soligor, new in box for $23. Smile

Nice, Soligors are often under rated, I also find many of my Soligors to be very good Wink

Wow, the soligor really pops. Typically I've found that the shorter range zooms or 'framing' zooms as some like to call them are actually very good performers. I imagine it is easier to optimize image quality for these, from an engineering standpoint.

Well my Viv 28-85 is very good at close up:-

I think in good part we're looking at low cost manufacturing resulting in a greater sample to sample variation vs. the high cost outfits.

You found a good Soligor, in an alternate universe the Viv may have been the better lens. Wink

Revers can you post a side and top view of the Soligor. One showing the serial number. So we no which version to look for.
I still need that focal length, and I want to get a good one. Smile

My vivitar 28-85 was a pleasant surprise as it was made by Kobori "77" which was supposed to be inferior to Kiron etc

Hmm... If you want a really nice bargain 35-70 lens, try Olympus Zuiko 35-70/3.6. It's very, very good, and can be had inexpensively. It's a parfocal design, too, meaning the focus point stays throughout the zoom range. Not quite as contrasty as the Contax Vario-Sonnar 35-70/3.4, but costs 1/3 the price of said Zeiss.

This Soligor is a very good surprise ! Smile

Old MF zooms are not all bad !

I'm surprised at how good the Soligor is and how bad the Vivitar is.

Bad copy on the latter maybe?

Revers, Thank You. This is the missing code 5 lens I have been looking for.
Now I just need to figure out the maker, so I can add it to the Soligor Identification chart. Very Happy Very Happy

My experience with Vivitar zooms is underwhelming. I am much more impressed with Tamron adaptall lenses. This Soligor looks like a very nice find.

Hmmm, performance of that Vivitar sucks. Sure there's no haze or fungus on the glass? I love a lot of Vivitar primes, but I've got mixed experiences with Vivitar zoomlenses. Anyway, yesterday I've won a Vivitar 70-150/3.8 on Ebay, which supposedly is pretty good.

If you want a top quality 35/70 at minimal price, look at the vivitar 35/70 3.5 one touch (made by komine 28xxx)

I made in 1985/1986 a comparative test of both viv 35/70 3.5 - constant aperture - and Zuiko 35/70 3.6
Quality is SAME except on 35mm full aperture where zuiko is better
At all other focals/aperture combinaisons, quality is same

Which vivitar 28/85 3.5/4.5 (the kobori version 77xx ??) and which soligor 35/70 3.5/4.5 (sun ,samyang ... ??)

ps : do not forget that 99% of 28/85 are lower quality than 35/70

I do not know which Viv it was but it was new in box. The Soligor SN 59***** in PK mount is made in Korea according to the box but no origin on the lens.

Samyang made = Usually medium quality but Some very good lens in the range.
