優點:
(1) light weight, lighter than Canon DO lens (same range)
(2) very cheap price.
(3) Very Useful IS, I try to turn off it's IS to take a photos, then I turn on the IS to take a same view photos. The two image is completely different. It can reveal the IS is 100% useful & workable.
(4) Long range, I understand Canon 70-200 f/4 IS quality is better, but when you need the range 200mm to 300mm, then you need to run. Therefore, the range 200mm to 300mm is definitely useful, specially in some shap shot and urgent situation.
(5) The picture quality is excellent with UD element. I have Canon 24-105mm L lens. I compared it with Canon 70-300mm. I found the 70-300 lens have about 90% quality of L lens, but the price is only half. It is a real bargain.
(6) low profile, when you are at the beach or street to take photos from stranger who will not easily discover due to the lens appearance is very low profile.
(7) solid built. I found the quality of this lens built have no obvious different with 24-105mm
(8) too much 優點 which you need to find out.
缺點:
$4150 HKD, no缺點, I bought it at Telford Plaza Pak Lo Wui today.
評價:
The lens you should try. I personally consider it as the most excellent lens among the lens in price of about $4000 HKD.
