請問canon ef 400 f5.6 + 2x or 1.4x 好定係 sigma 50-500 + 1.4x or 2x 好?

[gaiuswong]

質素更係canon ef 400 f5.6 + 2x ,ef 400 f5.6 + 2x .......唔平架喎.....

定焦靚得多，當然價錢都成正比啦！

我最近把大白轉了一支EF400mm f/5.6，質素一定比大白在400段好上數倍。各位要注意這鏡在配上原廠的1.4x或2x時，都是沒有AF的。

但係用呢支來影雀仔, 會唔會力不從心? 因為我驚手持時會手振

i have a 50-500 and barely use it (just post to sell it) - the L is really a different story (so is the price). alternatively 100-400mm maybe but you need to like that push-pull system. cheers.

我很多時都是手持拍攝的，應該不是問題。它的重量還比大白輕。當然影雀仔焦距越長越好啦！但價錢便要幾何級數上的。

yk:
唔該哂!
咁我諗應該買400f5.6+1.4x

riverg:
唔係ma?!50-500 極少用?! 點解呀?

[riverg]

my 3 times with it:

1st time: bring it over to the temple of repulse bay to capture some wakeboarding picture - 500mm is not that enough

2nd time: took the picture of the moon on this full moon festival - so 500mm is so remote from reality.

3rd and last time - some pic with the kids and eventually i find the result better than my using the litte-white+TC. maybe it's just too dim in that occasion.

so i guess i dont know in what other occassions i need this one - when my wife picked up star-gazing and i have access to a 1200mm now!
