So I bought an Adaptall 2 90mm F/2.5 that comes with a Nikon adapter (should be with me in a day or two) and then someone pointed me to the same lens with a PK adapter. I was just going to use the adapter from my 35-70mm however I think I'll see which of the two 90's is best, keep the PK adapter and then sell on the remaining lens with the Nikon adapter.

I may then try to track down the spacer that gives 1:1 macro.

Nice one - was a good tip off by Marcus Rowland. I was sorely tempted to grab it!
I might have to pick one up in due course... I've a 35-70 that came in a job lot. It's seen much better days in the past I'm sure as it's now hazy and dusty up the wazoo. Fortunately it came with a PK adapter so I'm free to buy any mount!

Had five minutes and popped outside with the SP90 to test shooting at distance. It has a lovely smooth action when focusing. I'm still practicing getter sharp focus at large apertures (this was at F/4) so it's not perfect in this shot. This is SOOC so it can do with a bit of processing to improve the contrast.

This, with it's lower contrast, would look great in B&W.

I just bought a Tamron SP28-80mm f/3.5-4.2 CF Macro zoom too.

I'm an Adaptaholic!

Something that was close and sat still - unlike the blue tit

I bought a copy of the Adaptall 2 28-70 f3.5-3.5 (44A), largely because I had already acquired the dedicated lens hood. Took it for a 25 miles walk to the nearest mountain to my home and it did not perform well. Seems decentered, left edge is bad but in truth it only seems sharp in the centre on full frame. It will not be a keeper.

Personally, I'd want to know whether a lens was a keeper before I took it for a 24 mile walk.

Lovely scenes in any case.

Yeah, I should have given it a go before lugging it all that way!

Back to the SP 28-80 again and it is clearly a much better lens.

The question isn't whether you should have tested it before taking it for that long walk, but rather did you bother to bring it back

A more serious question. I can see some softness in the images, but not enough that I would have flagged a lens issue. Is it much worse / more obvious at full resolution or I'm just not looking at to see what you are seeing in these images.

fuzzyphoton · 03-22-2021, 05:37 PM

i have a couple 44a ... one is mysteriously stuck forever ... one delivers pretty well, at least on my 4/3 ... but it too much is overlapped by my 01a in focal length ... so the 44a leads a lonely life ...

Full resolution the images are very soft in corners and along the left edge / mid frame. They look fine at web size, but at full resolution you can see clear issues compared to the SP 28-80 for example. I also took a few shots of a village at various focal lengths and the central houses were sharp, but outside of that they were a real mess. Could be a bad copy of this lens, as I am sure after all these years you'll get good ones and bad ones and this one has a very stiff focus ring.

What is pleasing me is that the SP 28-80 seems much better than people suggest on full frame, it is not the most popular Adaptall lens (following on from the SP 35-80 which seems a lot more popular). I don't think it is as sharp as the hugely respected Minolta MD 35-70 f3.5 Macro, nor is it as flare resistant, but it offers more focal length and seems sharp enough to me (and flare resistance can be helped by use of your hand, even with the original lens fitted). Not to mention I paid very little for the SP 28-80.
