本身用緊7D, 但遲D手鬆D會上全幅, 不過未係時候. 想買支超廣角鏡影星同星軌, 最好係APS-C 同 FF 都可以用到, budget 5000 內, 副廠都係所謂, 謝謝!!

for such photo ,you dont need a very good quality lens,any kit lens is enough

u need a special filter for reduce light ( due too long time shutter speed)

Only lens under your constraints I can think of is the S 12~24

是什麼filter ?

現在星軌不是都疊相嗎?

[ChiuChiu1970]

要影到星軌一般曝光時間都要15至30分鐘或更長，即使用最低ISO100和F12，都會過曝，所以要用減光鏡。

懂得用減光鏡就用啦, 打好基本功, 搵個天同地都黑既地方影星軌會實際D

畢竟多一樣野照顧就多一樣野煩...某程度上用ND你會連個天既暗星光都減左...所以識用先好用

又或者咁講, 你個光差要去到咁又想影勉強到星既時候才需要用減光鏡.....

唔太明, 而家好多人都係曝光25秒一張, 停5秒, 再影. 反幅做100分鐘到, 跟住再疊相, 點洗長開曝15-30鐘咁耐.

咁我聽大家意見買 sigma 12-24 啦, 相問APS-C 同FF都ok嗎? 我見1, 2代差1000千, 有乜分別?

謝謝!!

[singho1122]

sigma 12-24 唯一一支通用APSC and FF 的超廣角，有新一定買新，2代變形處理做得更好~~

二代表现更佳
