First images Soligor 105mm f/2.8 (Sun Optics)

[caspert79]

I'm quite pleased with this lens. It's build like a tank, and very tiny.
All images wide open:

In this image, there's softness at 100%. Maybe because the subject is very close.

There seems to be much less softness in this image. Probably because of the larger distance to the subject. It could also be, that the reflective nature of the tree bark causes softness.

Another 100% crop of an image @ f/2.8:

Plenty of detail.

Then, an image of a larger distance subject @ f/2.8:

If you click and watch the image at full size, you can see color fringing around out of focus objects such as the windows.

Very sharp results.

This looks surprisingly good for a thirdparty lens from the 1970s. How does it fare near the borders or in the corners ? My Auto Vivitar Telephoto 105 mm f/2.8 (37xxxxx so supplied by Tokina) from the same period needs to be closed to f/5.6 for corner sharpness while it is perfectly OK in the center when wide-open.

Nice shots!

I have that lens too and was also surprised that it was so good.

[caspert79]

Oke, now infinity test. 100% crops. First the center:

Obvious softness / glow wide open.

Then the extreme corners:

Unfortunately the extreme right corners are much better than the extreme left corners, so something seems not properly aligned. It could also be the cheap Chinese T2 adapter. Maybe I should consider buyer another adapter.

Hi. Which version of that lens is it? Could you post a picture pls? I have a Cunor which looks very much like Tokina made.

My copy is an early pre set version that is probably a Kawanon made lens with the H5 serial number. The style of the lens is a very common one with the O<- ->C pre set ring. I have / had a few lenses with this design.
It's a decent lens, I've had it a long time and use it quite a lot.

[caspert79]

My first impression of my Sun lens up till now: compact size, very good build quality, pleasant rendering, good bokeh both open and stopped down. Wide open softer than Topcor /Nikkor and Minolta equivalents, but probably perfect for portraits. Gets very sharp once stopped down a little. Quite an old lens so doesn't like direct light sources, at least not wide open. Corner performance yet to be determined, hopefully a proper adapter will help with that.

By the way if I learned one thing it’s not to rely on cheap adapters. First one I ordered didn’t even fit my camera, it was thát bad. Inconsistent corners with the second adapter.

could this lens be a sonnar opti formula ?

This line of lenses marketed by Soligor (and produced by different makers) seems to have a sibling in Vivitar disguise.

I previously tested its later Tokina-made variety and remained well satisfied with the results. Yours, from the earlier iteration, look very convincing, including colour procession and bokeh.
