希望樓主努力搵下文章,
學下咩叫(APSC下的)安全快門,
IS既計法, 咁就知道IS有無用.

1/8s, 就算3級IS, 都只係 1/64s, 仍算係較慢的快門呀.
IS 唔係萬能, 但的確有用. 當你用live view, 再放大時, 就見到is work緊了.
我唸叮噹CHING既意思係, 200MM鏡, 係FF機既安全快門係 1/200s, 但上係aps-c機, 安全快門就要去到 1/320s 了.

1/8 都手定定...... 咁要視乎你用幾mm焦距先?
我用 10mm 既話實得 !

"The old wives' tale about using at least 1/30 or at least 1/(focal length) comes from a general observation that for most people, you'll get about 50% sharp shots at that speed. " from

不過講真, 安門快門, 都係參考架姐. 盡可能提高快門速度啦.

你說得對吓Kalkal! 安全快門同錢一樣，越多(高)越好！但強將一啲錯嘅concept加落去實屬可笑！咩咩一定要1/focal length X corp factor.......就係因為有人咁講，所以好多人都以為corp機真係會把影像physically放大！

reflexboy, discuss with u about safety shutter speed is fun & informative
why don't u
1. start a new topic on safety shutter & let me explain in detailed to u again
2. start a new topic on mirror lens made of mercury. Seems u like mirror lens very much (reflexbxx), why not pay more attention to it?
I love photography, everything related to it are my interest, start & new topic & let me and other forum reader clear your wrong concept.
Otherwise u ruin the frame of a NPS.
I am not a CPS nor NPS member. I am just a beginner of photography but welcome to share my experience with other photography lovers.

I can tell u the fun has only just begun! I welcome u all to open a new topic on safety shutter speed and have further discussion there yet again.
Nps, cps membership is nothing to me. But this is something u do care about! What a shame! Cause u hang it on your mouth no matter where you go!
命裡有時終雖有，命裡無時莫強求！
