All in one conversion

Just sharing some information.
This filter will prevent contamination if your camera's sensor filter is replaced with clear glass

Same concept as this thread but they came up with a countermeasure to IR contamination for normal shots

Maybe a bit troublesome to change filter but you can use one camera to shoot normal shots, astronomy, IR with different cut-off.

That Clip looks interesting, fatigue.
Why? Because it can protect the sensor against dust contamination!
But I note with disappointment when it says that EF-S lenses cannot be used.
This will mean many APS-C and APS-H Canon cameras that are fitted with this can only use EF lenses.
As below:

Am I correct here, Fatigue?

Yes, you're right. Not for EF-S lenses.
Anyway, quite a number of EF-S lenses are not good for the IR. :bsmilie:
But the luminance filter doesn't come cheap.
Maybe some imitation filter will come up if the concept becomes popular

Nice find... A bit pricey for USD 89.95 and not to mention the conversion cost.... Worst part is it's only available for Canon.

UV/IR blocking filters doesn't come cheap as well and of course you will need another IR pass filter for IR photography. A second hand unit can go as low as USD 200. And for the pains and hassles of changing/stacking filters and settings, I would still prefer to have a modified cam. But that's me...

This filter is something that is clipped on in front of the sensor after the low pass filter has been removed.
Gentlemen, in my mind, I am thinking of this more as a sensor dust preventer. If it is so adequately sealed as to prevent dust from entering, then the price may be worth it.

Hi there all IR sifus,

I am new to IR photography and is contemplating replacing the "hot filter" on my D80 with plain glass and I noted that sifu Nenjia said something about CC1 filter on the front of the lens so that it will shoot as a normal at the previous posting as shown below--

What make or brand is the CC1 filter and is it easily available? Where to purchase & how much does it cost? Thanks ahead for feed back.:dunno::dunno:

Removing the anti-aliasing + IR cut filter and replacing it with clear glass would cause non-ir pictures taken to be susceptible to aliasing.

 

[Josh Ho]

Point noted Sifu 'irphotography', but are the anti-aliasing filter a separate unit from the IR cut filter? What the differnce with those IR modded camera, aren't both these filter replaced? Sorry for what seems silly questions but I still learning.....please keep inputs coming---THANK YOU in advance!

Some guys intentionally remove AA filter (a.k.a blur filter)

Now you are not making any sense :bsmilie::bsmilie:

Alamak... actually don't have to spend any more money just to get our IR photogs sharper. Getting IR photogs straight out of cam is only half the game. There's still the need to PP and 'sharpen' them in any type of photo-editing softwares available.

Sometimes IR photogs look good in soft and dreamy mood. And sometimes IR photogs also look good in sharp and crisp. It boils down to individual's artistic intention, same as how we want some colours to look in the post PP.

You guys are so humble. :angel:

Let me try

Modification ---> Filter --------------------------> Effect

Stock ---------> Blocks UV and IR + blur filter ---> captures visible light

IR modified ----->Blocks visible light/allows IR ---->captures IR light only

Clear glass ------>Clear glass -------------------->allows all lights. effect will depend on filter used on lens

HR ------------->Blocks UV and IR--------------->captures visible light and "sharp"

Yup, Sifu 'Fatigue' ...the light at the end of the tunnel is getting brighter and the picture clearer....thanks
