Both wide open, iso 3200 with noise reduction at -2. jpg's straight from camera. Just resized.

Quick levels adjust in faststone - it's free and just the ticket for some quick and easy editing:



Yeah the 105mm is a good one, mind you they're all good, the 105mm, all the incarnations of the 135mm, the 200mm adaptamatic/adaptall, all rather similar in fact. The 105mm has a relative scarcity cachet and IMO is a more practical FoV on apsc so desireable for that. But given that its price is often on the same level as a SP 90mm macro, well I would go for that lens over the 105mm just about every time.

I have the 90mm and the 135mm f2.5 - just slowly going through them all with the new Fuji + Speed Booster setup. Have to field the 90mm soonish, but I also have some nice Contax Zeiss pieces and some other nice Vivitars Very Happy

And thanks for your edit. I had set the floating iso to be max 3200 and fixed the shutter speed, so the camera was unable to adjust according to the conditions. My bad. Like I said the Fuji is new Very Happy

That's quite good. In good lighting I suspect it would look amazing.

There seems two tamron 105's. One is called Adaptamatic, which looks like Nikon 105mm; the other one is called Adaptall 105mm, which looks slightly shorter. Yours is? I guess the optical formula is different judged by the dimensions of the lenses.

Updated the title - thanks for the headsup! Had never heard of the older version.

As you can see from these legacy tamron pages, the specs are very similar.

The latter lens can also be found with an adaptall mount but it's rare- the earliest adaptalls were mount updates of the adaptamatic lenses, see for example the 300mm f5.6.

A couple of more in good light... just resized from camera jpg. No added sharpening. Either wide open or at f2.8.

Edit: please click through - I think the forum software does something that robs the images of their sharpness Crying or Very sad
