Originally posted by res3567 I bought a new Quantaray 70-300F/4-5.6 from a Wolf Camera store that is closing at a smoking deal.
The lens has a *Macro* mode that locks the lens to 180-300 focal range which throws the barrel out even further. It works great in Macro mode but in regular mode and macro it takes the camera's moter a long time to autofocus the lens.
This hurts when trying to capture moving small subjects such as birds.
Has anyone had any experience with lens?
Is the Pentax 55-300 better?
Does it have a good close focusing abilities?
Does it autofocus faster?

The lens' *Macro* mode.
Yes I had your lens and the Tamron, they are one and the same. However the older Ritz 70-300mm telephotos where Sigmas they way you can tell is the filter size. If your lens uses a 62mm filter its the Tamron, if it uses a 58mm filter its the Sigma. The Tamron is the better of the two. And you got a great bargain. Its the one thing I wished my Pentax 55-300mm could do, "Macro"
I tried calling around to get the 70-300mm just to get the macro function of that lens which is great, but no one had it in stock
enjoy the lens for what you paid
.
BTW the Pentax is no faster in AF moving objects, forget about BIF with the DA55-300mm. Its a bit better in the 200-300mm range, but for the price its not worth upgrading yet, get your moneys worth. Its really a good lens, you have to learn its limits and how to deal with them in PP and you can make some great pics with it.
