35mm FF Lens

librazhy

唔講解像度﹐唔講焦距﹐唔講散景﹐唔講一點幾CROP RATE

淨係想探討35mm Full-Frame LENS 放在 APSC機 能否100%將潛能發揮到盡﹖
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~




若要想100%將Full-Frame LENS 發揮到盡﹐是否須要一個 Full-Frame body 搭配﹖



~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Lens 將外間的光投射入機身﹐機身入面的光點分佈(SENSOR的覆蓋面)是圓的還是長方形的﹖Full Frame Lens 將外間的光投射 入機身的覆蓋率是比APSC SENSOR 大﹖ 還是大小剛剛好﹖

*能否100%將Full frame Lens的潛能發揮到盡﹖
*DX-Lens ->apsc=光折射small IMAGE sensor?
*FX lens = bigger 光折射 IMAGE sensor覆蓋面? waste of outer edge of light?

what are you trying to say/ask.
basically you just "waste" the edges -that's all

or in other words
if you get a lens optimized for full frame
then u waste all the technology and cost that goes into the lens

is SD1 apsc?

yes, unfortunately

librazhy

putting Full-Frame lens on apsc body ......  maybe its a waste of outer edge.

I'm gonna attach a picture to illustrate what I want to say/ ask

pls wait for a bit, need to draw & upload

the sizes may not match, but the circle stands for the Lens 光折射 IMAGE sensor覆蓋面

and the rectangles stands for sensor

upper left is apsc lens on apsc sensor

lower left is full-frame lens on apsc sensor

bottom right is full-frame lens on ff sensor

upper right is apsc lens on ff sensor

Regarding the concept in my brain, is it correct?

so what the hell are you trying to demonstrate?
