Whenever anyone asks about the DA*300mm, I tend to link to this post. Note the large photos of the birds are '100%' crops, i.e. enlarged to 100% in photoshop then cropped to fit the screen.

It works well with 1.4x (Tamron) or 1.5x (Kenko SHQ) converters as well, both 100% crops:

My 17-70 was terrible. It would not get a focus lock at the long end or even close to it.

The focus is very fast and not well damped with a very short travel, it tends to overshoot and then over compensate in certain situations, resting the tip of the index finger lightly against the focus ring resolves the issue.

Bump, still available.

Ah, understood, you tend to get used to the "feel" of certain equipment, I always find it a little disconcerting using 2 things very similar but not identical

The DA*300mm which I now have is slightly better wide open, nothing in it a f/5.6 and beyond. It's a bit messy for MF. AF is OK.

I found MF perfectly acceptable, especially since you have Quick shift for when the AF gets lost and can't lock, just needs a quick tweak manually and jobs done.

Of course there are the older cheaper F*/FA* 300mm lenses.

I use a F* 300mm f4.5 .. because it was half the price of the DA*, IQ is just as good and I have a DA* 60-250mm so didn't see the point of a SDM 300mm.

Absolutely, the old Sigma 300/4 APO TELE MACRO is another fine lens if you can find one s/h, personally I'd like something a little longer for wildlife a 400mm f/5.6 perhaps.

Hi Philip, hope it helps, the SDM is a positive advantage at close quarters as well being virtually silent and of course it's eviromentally sealed with great build.

Hi Philip, most of the wildlife shots on my profile are with the DA*300, the Kinfisher is with a 1.5x rear converter on the rear of the DA*300, it's one of my most used lenses and a favourite. The 3rd image above is 100% crop of the 2nd image. BTW it's not for sale:wink

It's a very capable piece of kit IMHO
