 500D close up lens 一問 Post time: 8 月 30 日 |
|

有c兄用過係小白/小小白IS嗎?
最近同最遠對焦距離會變成幾多?
(500D close up lens 唔係相機)

其實由個名, 已經話了你知, 太約對焦是約5cm!!
都難用, 不過D質數就好得囉!!!

Ching, 你係唔係想問SW/SSW IS 加close-up filter 最近對焦距離?

CANON 500D (=> brings closest focusing distance from infinity to 500 mm) (= +2 filter)
CANON 250D (=> brings closest focusing distance from infinity to 250 mm) (+4 filter)

how about 最近對焦距離? that depends on your lens itself, e.g. closest focus distance of a lens is 1.2m, with a +4, the closest focus distance is around 3x cm

Obi-Wan Ching,
If so...apply a 500D filter to SSWIS, the closest focus distance should be around 60 cm, right?

"If so...apply a 500D filter to SSWIS, the closest focus distance should be around 60 cm, right? " <==== if your lens is set to infinity, the closest focus distance is 50 cm from CCD plane
if you lens is set to the closest focus distance, the closest focus distance should be less than 50 cm ( I guess around 30 cm, as I don't have SSWIS)
