優點:
10x zoom range, a lot of fun to use.
Push pull zoom allows quick zooming from wide angle to tele in split seconds.
Very good quality. Great colour redention, great sharpness.
Easy to use.
IS works great (can capture sharp picts of cats and dogs at ISO 1600 F5.6 300mm 1/60s in indoor area, provide it is not running or in too much action)
Looks very cool.
Built like a tank.
缺點:
It could be heavy for some, but it is a matter of getting used to.
Sometimes, the switches (AF/MF, IS) can be accidently switched.
Its a very eye catching lens.
Slow focusing in low light condition, compared to F2.8 zoom lenses.
Net report shows there is a slight degree of barrel distortion at 28mm, but in real world usage, it is a lot better than the report claims. If you know how to get around it, there is no problem at all.
評價:
I must say this is a great purchase without any regrets.
This was bought prior to my holiday 2 months ago along with my 16-35 II and 35L on a 1 series body. This combo will cover 99% of your travelling needs.
The great thing about this lens is you could capture a lot more shots in different persepctive than a 24-70 and 70-200 combo, because you can just go from wide to tele so fast. And it is so convenient there is no need to change lenses all the time.
There are reports from the net doubting the quality of this lens. From my personal experience, I dare say this can rival the 24-70 and 70-200 in terms of sharpness and will have identical colour redention. Even at 300mm, the quality is very good as I do not observe increased softness in this focal length. (but please don't compare this with F2.8 or F4 300mm, it is just not fair)
If there is going to be an update version of this lens. I wish it can go wider to 24mm, with a more advanced IS system.
With the continuing improvements in ISO performance, this lens will only be more and more usable.
