Pros: Risolvenza high at all focal lengths and already at full aperture, f / 4 fixed, excellent build quality, SDM

Cons: absence of sealing, is sometimes reported difficulties hooking dell'autofocus to 70 mm

Opinion: The DA 17-70 is a great lens in my opinion, with A resolution as not to regret the fixed lenses at all focal lengths and already at full aperture. And 'f / 4 fixed and has a great zoom range from wide angle to medium telephoto. Clearly this makes it faster Zoom basis (the DA18-55 in its various versions) but impacts on blurred, which is clearly not that of a lens with aperture f/2.8 or even more open. It has an excellent control of flare and chromatic aberrations and a really high build quality. rnrnAlcuni users report difficulty hooking autofocus 70 mm, although personally, I never had the problem on my esemplare.rnrnE 'perspective that sicuamente board for ease of use and overall quality, sin only by the absence the sealing.
