很難。問題很多:
1.
首先遇到的是保固的問題,要改變必須打開機身,破壞封印。
2.
想拿掉
IR-CUT-FILTER
時必須看它如何固定,是否會造成
CCD
或
CMOS
損壞?
3.
聚焦偏移,必須用相同厚度的透明玻璃填補。
4.SENSOR
的受光條件已改變,想拍攝一般影像時必須在鏡頭前加一片原來被拆掉的
IR-CUT-FILTER
,但是想拍攝
IR
影像時必須卸下
IR-CUT-FILTER
,另外加上
IR-FILTER
。

解決方案:
1.
The Canon 10D, 20D, 300D and 350D, Nikon D100, D50, D70 and D200, and Fuji S3 Pro can be converted to IR-Only, picture AF and viewfinder AF. The Canon 5D can be converted to IR-Only, picture AF at the moment. I will probably be able to convert the 5D to AF AF in about 6 weeks. Once I get time to do more calculations, experiments and order the optics, I will get the 5D done as well. Please note that some others that convert cameras don't do any AF modifications forcing the user to shoot at high f-stops to maintain focus. We also use custom double coated filters and a class 100 clean bench.

本人想順便詢問
SONY A100
是否有如同
7X7/8X8
的夜攝功能?如果有夜攝功能,一切問題就迎刃而解。
