Fujifilm Finepix S700 disassembly and infrared conversion
My Canon 20D, converted for IR was stolen in Barcelona, so we with Irogoto are decided to build new IR camera — from scratch, in hotel room. Day after collecting parts we was ready for 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 with no dust, make numbered boxes for screws. Or use adhesive tape to stick screws on it.
Converting S700 for IR is much easier than converting Canon DSLR. You will able to do it within a 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 it's place precutted 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 power on until you put back cover.
The camera have internal focusing system (lens didn't move outside) and screw thread Ø 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 are block IR and after screwing in on the camera, it will operate just like unmodified camera.
I see no sense on putting filter in front of 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.
