I'm a little bit advanced amateur and I have the Pentax K20d.
I only have the kit lens (18-55) and I'm thinking of what would be the smartest move to go for next.
I'm mainly thinking of going for the da* 16-50 and later maybe the da* 50-135 or to go for the da 17-70 when it will become available and a few primes with it.
I'm also thinking of getting an external flash but it's really difficult to choose between Pentax AF-540 and the Metz 58 AF-1.
Could you please help me with these decision and maybe add other options?
At the same time, I would like to ask why people tend to buy repetitive focal lengths.... Is it quality of the DA* versus the DA?
for instance, if you do want the DA*s why not just sell the kit lens and get only the 17-70 and the 50-135? You are only overlapping a small range but reducing your gear by 2 lenses...
Can someone explain me why I tend to see people doing that? (overlapping f lengths).
I have only begun to look at what glass I want to pick up the next few years, so can not really advise - But the Kit DA 55-200 is not bad for the money either. At least you get covered for a wide range with the two.
As to why so many people keep collecting up glass - I don't know! For me I have a few things I want in my kit, and a few that are going to be trial and error to find the one with just the right sweet spot for what I want to do at the moment. Even if I end up with a few in the same range or close it is likely I will hold onto them. The plan is to update the body, say when something like the K30D comes up. So then I may need, or want, the same range of glass on both bodies at the same time.
I bought and sold a fair bit of SLR 35mm years ago - now I wish I had just held onto it all, but I was young and needed the cash at the time.
