Thank you for that info pacerr, it makes alot of sense but I'm still a bit disappointed that my "new" A*300 is not as good as I had hoped. so I have decided to buy another lens (not right away though) I have been looking (online) at some Sigma reviews and Pentax reviews,
I would like something close to 300, I think a zoom would be more versatile for me So I'm thinking I'll probably go with a DA*60-250 f4. I would like an f2.8 aperture though which seem to be more common to the Sigmas.
I'd be interested to hear peoples opinions on which lens would be the better lens to go with (I know you are all bias! haha), I have to say I'm pretty blown away by the quality of alot of the photos on here, some are super sharp, that's what I want to acheive. anyway, I'm keen to hear your thoughts.. thank you!
