is a 18-200mm sigma a good swap for pentax 18-55mm and sigma 70-300mm?

tomell · 06-18-2010, 04:57 AM

my camera company sent me the wrong order but has offered me this switch. is this a good offer? am i being ripped off or am i better off spending a bit more to get a better all round lens to start off with? i will mainly be taking photos of my children so i need a lens good inside and out. i'm getting so confused with reviews so some advice would be really great.

I have owned Sigma 18-200mm. It's a beautiful lens in a small package and below are some pictures taken by 18-200mm. However, lately I have been using Tamron 70-300mm Di more due to the better reach and it's also slightly faster at longer end. I never used Sigma 70-300mm but if it's APO, I only heard praises. Pentax 18-55mm is a fine lens too.

Quality-wise, not quite as good by almost all accounts, but not that you'd notice without pixel-peeping (looking at prints with a magnifying glass, or doing the equivlent on your computer screen. Convenience-wise, sure, one lens is better than two.

But don't assume that *either* option will be great for indoors, at least not unless yo use flash. Eventually, you'll probably want another lens specifically for low light use. But such a lens wouldn't necessarily make sense to start out with in place of the options you are looking at, so I'd say, cross that bridge a later once you're more familiar with what you've got any limitatins you find your running into.
