Hi Hans,

The A* (as well as the K and M*) 300/4s focus to 3m, the FA* 300/2.8, F* and FA* 300/4.5 all focus to 2m, and the DA* 300/4 will focus at 1.4m. The A* 300/2.8 focuses to 4m. IMO, the sharpness improves as does CA/PF in each newer series over the last when they made changes in the optical formulas.

Off Topic, but I think it's interesting to note that the outstanding results that mole gets with his A*300/4 are even more remarkable when you consider that his copy has quite a few nasty scratches on the front element (I'm assuming it's the same lens). He attached a photo of the front element in his first post with this lens:


Another of our members, Roy (robar), had one that looked like the front element had been cleaned with a cinder block, but you couldn't really tell from the pictures if he stopped it down. Here's a pic of his lens:

Goes to show you that great lenses just refuse to die.

Wonderful series, Mole! The A*300 was my first * lens (still have it by the way). It's a wonderful lens even though it won't focus very closely - definitely not a macro or even a good close-up lens. But it has beautiful color and excellent sharpness, as well as being much smaller and lighter than the DA*300, which is the reason I keep it, though I haven't used it very much since purchasing the DA.

I agree with Scott's assessment of the two lenses, the DA is definitely better as far as PF and CA. I found the sharpness difference less noticeable - with the comparison shots I did it depended more on which lens had the better focus. When I managed to get both focused at the exact same point the DA*300 was slightly better, but I had far more shots that were inconclusive because of slight focusing differences. The A* is just such a work-horse of a lens, well worth it.

Hans - This groundhog sure was cute - a tiny one smaller than my hand, but already "fat & fluffly" and ready to eat up someone's vegetable garden! Hope all your rain is bringing plenty of green & bloom!
Scott answered your 300mm question quite thoroughly. I will just add that the insect pictures were not taken with the A* 300, but with the Sigma 70-300. Only woodpecker, black locust & crossvine taken with the A*300.

Tachikoma - So glad you enjoyed the little butterfly and the odonates. Isn't it amazing what a diversity of small "critters" our earth holds!

Scott - Thanks for your thorough and detailed answer to Hans' question. You are definitely the long lens expert! Yes, this is still my wonderfully scratched-up 300 - it works, and the price was in my (tiny) budget...

Harriet - Glad you enjoyed these, and thanks also for adding to the lens information...

Kevin - Thanks so much! Here are the identifications: The dragonfly is a Lancet Clubtail. The blue damselfly is a Familiar Bluet. The greenish one is a female Eastern Forktail.
