Fujifilm Finepix S700 disassembly and infrared conversion
My Canon 20D, converted for IR was stolen in Barcelona, so we with Irogoto decided to build new IR camera — from scratch, in hotel room. The day after collecting the parts we were ready to do it.
Fujifilm Finepix S700 was chosen just because of it's price — less than hundred euros on sale.
So, here are the steps to convert FinePix S700 to IR-enabled camera:
Preparation. Tools and Parts
Herewith soldering iron, solder and cutter will not be nessesary.
Prepare well lit place without dust, make numbered boxes for screws. Or use adhesive tape to stick the screws to it.
Converting S700 for IR is much easier than converting Canon DSLR. You will be able to do it within an hour or less.
Disassembling FinePix S700
Unscrew 1 and 2 (short ones).
Unscrew 1 and 2 (long ones).
Unscrew 1-5. They're different sizes. Screws 1 and 2 are long, 3 and 4 — short, 5 — the shortest one.
Note little triangle with a flash. Fuji is telling truth — it is REAL risk to get electric shock.
Unscrew 1 (short one).
Gently lift up back cover.
Disconnect marked ribbon cables. They are flip-type — just flip up the dark lever to release the ribbon cable. Remove LCD.
Unscrew 1-5 and remove protective shield.
Unscrew 1 and disconnect ribbon cable 2 (yes, it's flip-type too). Gently lift up the circuit board.
Attention! Don't touch contacts, marked with con the picture! It's a high-voltage capacitor for internal flash, and it can really electrically harm you. Better to put piece of adhesive tape on it during disassembly/reassembly.
Unscrew 1-4, don't touch ribbon cable.
Here we are. The reddish glass is the «hot mirror». It is not glued. Just remove it and put on its place a cut-in-advance piece of optical glass with dimensions 9×7×1 mm. Make sure you don't leave dust and fingerprints on glass or sensor. It will be really boring to disasembly camera again just to remove occasional dust particle.
Reassemble camera by following the instructions backward.
NB. Camera will not switch on until you put back the cover.
The camera have internal focusing system (lens didn't move outside) and screw thread ? 46mm.
I'm using three kinds of filters
In future I'm planing to buy 46mm screw-in filters — sepia, ND and special IR filters (Hoya 93 for instance).
There are "IR-cut filters" on sale — they block IR and after having them screwed into the camera it will operate just like an unmodified one.
There is no sense in placing the filter in front of the sensor. You can't change lens on this camera, so you'll need just one set of filters. And the possibility to change filters will give you much more flexibility.

I see no sense on putting filter in front of sensor.=== There is no sense in placing the filter in front of the sensor
Camera is high sensitive to IR== Camera is highly sensitive towards IR
even with much more thin glass I used and on f/3.5 shoots are still sharp== even with a lot thiner glass I used and in f/3.5 mode the shots are still sharp
Working ISO is not greater than 200== Working ISO is not higher that 200
unusable==useless (Более корректное слово)
But in common daylight you'll often get shutter speed not slower than 1/60==But usually in a daylight the speed of the sutter is starting at 1/60
However it don't set white balance other than «auto». == However the white balance setting is nothing other than "auto"
who need ==who needs
И опять-таки еще в некоторых местах - артикли...
