有冇nikon師兄有新個支sigma 24-70 ?

24 @2.8 同[email protected] 表現如何? 有冇走焦問題?

有冇走焦要鏡夾機,試過先知,答唔到你的,
有C-HING話買左3枝定焦都有走焦,
亦有話用canon機易走d,
我自己用nikon機,
sigma 17-55 os同70-200 os都冇走焦,
最好帶機去試

As far as I know,
1. with Nikon FX bodies, seldom heard of any focus issue
2. with Nikon DX bodies, there is a chance of getting focus issue, e.g. D7000
3. with Canon FF or DX bodies, the chance of getting focus issue is 50/50

I use Nikon D700 and have no problem with Nikon, Tamron and Sigma lenses.

我有同感
以前試過用一支Nikon AF 50mm f/1.8 non-D
用落F5無問題
但用落其他中階model body就不能AF
後尾發現支鏡係接觸不良
亦証明Nikon Pro body係落足料做出來

Yes!  It seems higher grade models could drive the len more accurately.   I've tried some oldies on my D700, for example, 24-120 AF-D, 85 1.4 AF-D, Tamron SP 24-135, etc., with 100% focus accuracy.  I do have other AF-S lenses but that Tamron 24-135 is now my walk-around zoom coz I like the range, size and sharpness that it delivers.

係咪HSM果支? 我用過係C 450D/5D, 2部機都走焦. 賣左支鏡.
N D3100/D300/D700 就好好多. 而家我C糸都用番原廠鏡, N糸就用哂HSM(50.4/24-70). 有D 怕用S+C....
