I’m rather new to DSLR… I have tried my best to read and learn, but I still come out with a question which I hope all senior bro and sis could help me out.
I am looking for lenses suitable for a Canon 450D. Of course the suitable starter will be the 18-55mm f/3.5-5.6 IS kit lenses, or the 18-200mm f/3.5–5.6 IS.
Yet, something draws my attention: if I want to get a longer zoom range, I could probably choose the 18-55mm f/3.5-5.6 IS + 55-250mm f/4-5.6, instead of choosing the 18-200mm f/3.5–5.6 IS.
The combination is actually cheaper (from the price list I got from CS). And the aperture value is actually comparable (from my understanding)
But, is it mean that 18-200 is only one piece (don’t need to change) compare to 18-55mm f/3.5-5.6 IS + 55-250mm f/4-5.6 (2 pieces), thus more expensive?
Or, the one piece 18-200mm f/3.5–5.6 IS is actually better in terms of IQ, and other features compare to the 2 pieces combination?
p/s: roughly price get from CS
450D kit 18-55mm f/3.5-5.6 IS ~$1130 + 55-250mm f/4-5.6 ~ $360 = $1490
450D kit 18-200mm f/3.5–5.6 IS ~ $1760
