我想問, 我而家用梗 18-200. 當用 200 影花花時,
都係影得唔夠細緻,
但我見有其他 ching 加左 Macro Tube 之後, 效果好好多,

所以想請問, 如果想影 Macro, 但又唔想買 Maco Lens,
咁係咪要加 Macro Tube??
咁請問各位 ching 有咩野牌子同埋價錢介紹??

謝謝!!! :)

a set of extension tube with auto AF: > $1000
a set of +1, +2 close up filter: around $120 (china made, Apliu street)
a set of extension tube without any auto: $60 (china made, Apliu street), if u are not experienced, u can't set the aperture
Tarmon 272 90/2.8 macro $27xx

if u just want to play play macro, better buy close up filters because the AF can be used

FYI, there is new set of auto extension tube by Kenko, about $800. My friend bought it last week, AF work. You may want to consider that too.

用cloes up filter永遠唔夠用extension ring 影出o黍o既野靚!因為extension ring唔會影響鏡頭質素,用cloes up filter會!

"因為extension ring唔會影響鏡頭質素," <===== WRONG!

If u use extension ring, u ALSO enlarge the lens defects. That is, the resolution of the lens will drop rapidly if u use the extension rings with total length greater than the focal length of the lens.

agree

請問 Kenko Extension Tube Set for canon 有 DG 與 冇 DG, 有什麼分別?

"If u use extension ring, u ALSO enlarge the lens defects."

呢個唔係extension ring o既問題,呢個係你支鏡o既根本問題! 假設你用同一支鏡,用extension ring/tube做近攝,一定比用鏡前所加o既近攝filter好. 近攝filter無論d材料點靚, 都係隔o左一層野,o係光學上面,每加一層野o係前面,就會減低原本o既質素, 呢樣野係鐵一般o既事實.

如果如要放o甘大,你要加幾多塊近攝filter? 所以無論點, 都係用extension ring/tube質素較用近攝filter佳!

don't use brain to to experiment, use your hands!

I have both extension tube & close up filter, the photos taken with close up filter is far better than extension tube!

what the heck are those links for? can they prove anything? since u have both of those stuff. i would be greatful if u can kindly make a fair compairsion and post the result here!
personally, i don't believe in using close up filter and i've already told u the reason why i use extension ring rather that piece of glass! common sense??? i don't know! so, can u tell me the foundation behind your comment!
u know, the brain is the most important part of a human being. without it, u can really get things done!
may the force be with u!!!
