28-300 and 18-200 lenses lack a lot of quality. The following are the "must have" zoom ranges for your camera
: 12-24mm(wide zoom), 17-55mm (standard zoom) and 70-200mm (tele zoom)
Lenses that try to do that full range or even more are of mediocre picture quality because it isn't technically possible to ake a big range like that and keep quality up.
Hold on Nick......
I've seen this a lot on photography forums
, experienced photographers totally trashing the ultra zooms and scaring newbies into unnecessary lens purchases.
I agree that the 18-200 lacks quality especially when I compare it to my L lenses, zoom or prime. However you need to look at where people are coming from (p&s?), their level of experience, where they are and where they want to go in their photography
"career" before you push people upmarket.
There was a time when I was happy with my sigma 18-125 on a 300D. It worked will for me as I could carry it in my tank bag when I toured over Europe
by motorcycle. The photos were still better than anything I could do with a p&s. One lens for everything was convenient and suited me at the time.
I really think that those of us in the know should not be scaring people into spending more money
than necessary. The one size fits all can be a good introduction
to dSLR photography and can give people the chance to find out where they want to go.
Personally I think that for people just starting out on a budget
and without lofty ambitions, a cheap
and potentially disposable ultra zoom is an ok stating point as long as they understand the limitations. I would however suggest that if they are Canon that thy should also get the 50mm f1.8 for portraits and low light shooting as it is so dirt cheap
Like I said, I started with the Sigma, then after deciding to get serious with my photography (breakup gave me need for a hobby and more disposable income) I jumped straight to the 70-200L f2.8 and then the 24-70L f2.8 bypassing the intermediate lenses.
