I haven't tried it on K1 but tried 28-75 on A7/A7r and it performed well so should perform good on K1 too.

I will also be very interested in K-1 experiences with these. I have both and like them a great deal. Not in the immediate market for a K-1, but have kept/bought both of these with a full frame camera in mind.

=> I would also say in addition the Tamron 70-300mm f/4-5.6 would also be interesting

I will get a tammy 28-75 from a friend next week. my first one was totally off balanced with back and front focus and no chance to repair haha
but I think it will work great on the new machine. Report later next week then...

I use 'em both on my A7, Migelb, and since there will be no money left over after I get the K-1, they will be my standard and tele zooms on that too, whether they like it or not.


The IQ is great.

I just bought both along with the K-1, so I'll be sure to post my impressions as soon as they all arrive.

Ok, I got now 2 28-75 Tammys and both were not perfect. since I will get this second one which is slightly better but still needs a -10 correction for 100€ from a friend. I think I will take it and use mostly my FA50 and the DA35.
Somehow the Tamron lens is also vignetting wide-open. can anyone confirm this? I really like the vignetting its like a element of style and goes away when not shooting 2.8. I would say from 3.5 this lens shines. Really nice quality considering the pricing of this lens.

That's my experience with the lens too - on K-5 and K-3. f3.5 and it's awesome. Can't take a bad photo

But it is a strange lens with AF adjustment - on the K-5, no AF adjust, on the K-3, lots of AF adjust needed.

No vignetting wide-open that I notice. Probably some, but nothing that worries me.

after taking this glas for a ride again... I can say you can absolutely forget my copy at wide open 2.8... BUT from 3.2 the focus fits on -10 fine adjustment and I think it makes pretty cool shots. Took it for a little city tour today in JPG only. but the results were quite satisfying

Oh forget: since the K-1 is FF I think it is clear that the K3 and the K5 have no vignetting

I have a copy of tamron 28-75 and tested on the K1. no vignette at wide open and seem to focus well for me. No lens adjustment made.

It was a brief testing, will update more again when i have time to test again.

What about 70-200? Does anybody with K1 made any test so far? The ones above looking quite good.

my copy is literally unusable at 2.8 but from 3.2 I have a good focus and sharp results based on an other extended walk in the city.

I would also see some shots with the 70-200, this lens is on my wishlist for too long
