1. Cheap in it\\\'s class f/2.8, I buy mine at HKD2500 3 years ago
2. Light weight and compact compare to same class product
3. Good for APS/C because center part is sharp
4. Fast auto focus despite it is not AF-S
缺點:
1. Poor built, plastics cracked and screw boss are broken from a drop at normal table height on a wooden floor. I use glue to fix it now, but cannot open up for cleaning anymore. Over mould rubber on housing easily scratched off. My old manual focus Pentax 35-70mm lens after using for 15+ yrs and drop and struck many many times and are still in good working order.
Light to carry around
Hardly any distortion
Hardly any vignetting
Build is solid
Comes with lens hood and bag
Sweet performance on wide end.
缺點:
Front focus
Performance is kind of a struggle on tele end
評價:
I paid USD$ 250 for the lens, at the time when USD is low, so its a cheap lens for me to own for starters.
This lens is not too heavy to carry and has the advantage of a large aperture. Shallow depth of field can easily be created while there's virtually no distortion or vignetting with 450D body.
However, the downside of this lens is its front-focus problem. Performance at 60mm is a bit of struggle as it is kind of blurry. Focus speed is adequate as this is not HSM lens, but it is not slow.
Anyway, really not bad for a full frame lens with f/2.8 at USD$250 with 1 year international warranty.
1. Is it most longer focal length at its 24mm?
2. Is it most shorter focal length at its 60mm?
3. Is it similar to 24-70mm's specification?
4. Do any one who can answer my above question?
5. I am considering this len because the price of this len is reasonable and its focal length range and large 光圈 very useful.
6. where can it be brought? Because there is no storage goods in Wxxg Sxxxg. would DC Fxxxr be available? Please give your hint... if any....!
* I do not have this len. But I have interested in purchasing it shortly. Please give your valuable comment...! Thanks...!
