kenko L37 super Pro, Hoya super HMC 同 B+W MRC-UV我都有用

Kenko既玻璃最無顏色, 其餘兩隻有微偏黃. 但Coating有油的話難清潔.

Hoya既反光最少, 廠方宣稱既透光率係三者最高, 達99.5%

B+W 既coating據聞係最硬, 防水易清潔

不過就無試過將三種filter放響同一支鏡頭做實拍測試

Actually, from my experiecne, neithert of those specified ones are of the best quality ...

The top model for Kenko is their Super PRO L410 and this is not for sale outside of Japan. I don't seems to get decent result from Hoya, but that's just me.

In use , all of Kenko, Scheneider, B+W, Rodenstock is pretty much similar and insignificant in view of actual usage for difference.

Truth is what you see as a color cast is pretty much coating instead of real transmission, and we have to consider film ( and CCD ) do not see color as our eyes do ... shoot a tes target under sunlight and you will understand why I am nto too concern about that. Instead I am more concern about the transimission curve of the filter. All of Kenko, Hoya, B+W, Schenieder, and many make brands L37, or L39 had that drop off curve towards the UV range and this means they all have actually quite a large portion of UV spillage. The best UV I've found having the most accute driop off curve and good UV blacking is actually the Marumai Luminance series L400. Other than that, its the Fujifim Bandpass and sharp cut fileter ( By special order only , they were usually used in Cine ). And finally, I have no problem cleaning any of them, don;t knwon why people have this issue ( might be they just do not use proper tool )

The motto I have is so long its coated properly, with fairly decent transmission and UV cut off curve, and be used with a proper hood, then its fine. After, all, changing light condition and changing film had far much higher effect on the image.

齋睇玻璃外表, Hoya PRO 1靚過B+W MRC好多, 成像就要試過先知, 不過以小弟膚淺的眼光, 我想都係睇唔到有咩分別...... :oops:
