hello

i am hoping that some have experience with the kiron-nikon mount. I am planning to buy one, but would like to know how it perfoms.

Had the K mount version. Very good lens, but lacking in contrast wide open. Performance picks up a lot by f2.8

Pretty good lens. We have test results from it in the Kiron Klub files. There's also a Kiron 24mm f/2 version.

I have the Vivitar 28/2 Close-Focus in K-mount as well. Seen at this page (scroll down a bit).
I don't know if this one is made by Kiron? Edit: Ok, so mine is a Komine made lens (28xxxxxx serial) with 49mm filter thread. All of what I've written below applies to that lens only... Kiron has a 22xxxxxx serial number and 55mm filter thread.
Interesting thread about the difference between the two: http://forum.manualfocus.org/viewtopic.php?pid=104897

My experience with the Komine version on crop (40D) is the following:

- has glow wide-open, need to stop down to improve sharpness;
- bokeh can be really wild wide-open with busy backgrounds;
- quite easily shows polygonal highlights when you stop down a little;
- some barrel distortion (will be noticeable when shooting architecture);
- sometimes shows blue fringing in subjects like trees against white clouds;

- sharpness is good for landscapes but also for close focus when stopped down a bit;
- bokeh can be very nice when used properly;
- build quality is good (smooth focus ring, nice aperture ring, all metal).

When used for close focus the rendering can be quite sharp and contrasty. I like the lens but don't use it very much because often the bokeh situation isn't suitable. I got one for around 35 euros iirc.

I've been looking into these lenses myself, and I found that thread listed earlier. Then I started looking for samples from the Komine and found this:

That image has definitely seen some PP (sharpening, maybe contrast/clarity). Nice example though.

I have the kiron made version and it performs like crazy on close to mid-range. Infinity is still a problem though, seems that mine needs some adjustment (because it has floating elements). Very promising though, and I sometimes prefer it to my beloved Olympus 28/3.5

ahamb, nice listing, its the kiron version, serial starts with 22 and 55mm filter.
It seems it have some rather minor flaws, but nothing to worry about. As i was told in another tread, the aperture blades seems to be the biggest problem with the lens (oil).

From what u guys been writing this is a go for me, im actually getting very excited to try it out. I should be receveing it next week

txh for helping.

ulrikft: if i dont like it ill sell it to u, but the chances are small

Ulrik: Keep in mind that the example above was shot at (close to) minimum focus distance.

@biotar: Can you rule out the thickness of the adapter you're using?

I'd like to try (have ) the 28/2 Nikkor though. I'm sure it's a class above the Vivitar/Kiron.

I would think that's a significant part of the whole point to the Komine "Close Focus" version.

Hehe, AhamB: I know who shot the shot and he has written a bit about how it performs :P Close performance is why i love these kind of lenses got a 20 1.8 (sigma) that focuses real close, and a 35 1.4 (nikon, ai-s) that focuses reasonable close, a 28 2.0 would go nice inbetween those.

Fortunately yes, its simply too slim for this lens because it focuses too much past infinity...

@Ulrik: There's a Kiron 28/2 in Nikon mount at ebay now , ending within 15 hours. Price is still good (but it's in the US).

Should be better, yes, but it's more highly priced. The 2.0 is very affordable.
