I can't speak to the 90, but the 28-75 really isn't a macro lens. It will focus to around 16" if memory serves me, and it does very well at that. Sharp even wide open.

The 28-75 makes a nice portrait lens as well. It's been the lens that has spent the most time on my camera since I bought it (wow!) six years ago.

Hopefully someone with the 90 will chime in.

Okay, you asked for it...

These were shot at/near the close focus distance.

The 90mm is an awesome macro lens. At 90mm I would guess it should be pretty nice for portraits too, but I don't own one so can't confirm. I do own the 28-75 and it is an excellent protrait lens. I bought it for that purpose and have never been disappointed.



pretty good for close ups of flowers etc...

I have the 28-75 and it's a great lens, but it's not a "real" macro lens (max magnification is 1:3 I think). Still, it's close focus hability is very handy for portraits and general close ups.

All in all, your choice depends on what will you use it for more often. One doesn't replace the other.

I have the 28-75 as well, and I can attest that it does a decent job with macroing, but doesn't replace a true 1:1 macro lens. It is very sharp stopped down, but mine is quite soft wide open. I get some "bloom" like stuff in high contrast areas and no real detail like I can stopped down.

wide open:


f/3.2:


f/8:

On which camera do you get the "bloom"? I ask because CCD sensors have a tendency towards bloom, whereas C-mos sensors do not.

Which is better, a fish or a bicycle?

The two lenses are not really comparable in any meaningful way - one is a 28-75, the other a 90. If you need to take pictures at focal lengths between 28mm and 75mm, the 90 won't cut it at all, no matter how good it is at 90mm. And vice versa. Both lenses are great at what they do, but neither can do what the other does.

That is exactly the only possible answer. These are two completely different lenses with completely different application and a very small set of comparable assetts (28-70 at 70mm versus the 90mm).

Two of the sharpest lenses I ever owned. If I were to choose one it would have to be the 28-75.

a fair comparison would be a lens of the same purpose.

It happened both on the k200d and my k20d. Only wide open at f/2.8. Stopped down, it seems fine and by f/4 its quite sharp. f/5.6 to f/11 is very sharp. If you look at the image I posted above that was taken wide open and zoom in a bit, you can see what I am talking about.

f/2.8 -- notice the bloom, not an effect of post processing

f/8 -- crisp detail with no softness at all

I appreciate the sharpness. Although, my wife's favorite portrait of her with the Tamron was the one in which I had SR off...
