1. Lens module consist 3 motors - for zoom, focus and aperture. Than it is possible to replace them I do not represent.Originally Posted by lordtangent
2. The important condition of any optical systems is concurrence of optical axes and parallelism of optical planes. To make iе self - very hard.
3. But at presence of the corresponding equipment to make c-mount it is direct on the case of sensor, i think probably.
you mean if we remove the front lens elements, we can just slap on a 35mm lens and it will work?

Garm99,
Would you say that replacing the IR filter in the HV20 was as difficult as it was in the Canon Digital Rebel 300D http://ghonis2.ho8.com/rebelmodnew.html ?
Or is it easier? It seems like there are lots of opportunities for me to easily make a mistake, and seriously damage the system. (I'm particularly worried about prying off the IR filter if it is glued on very well. Are you saying that there is NO glue used to keep the IR filter in place? Just rubber, which is very easily separated from the rest of the unit?) What are the most difficult steps?
Thanks...
Glenn
First of all difficulty depends on your experience. For us it was easy.
We have not found out some any glue which holds the filter, only an elastic band from rubber.
The main difficulty - to overcome fear to damage dear HV20
A dust was probably the main problem. Now i begin post guide
Step #1
Necessary things:
Bright light, pure table, set of screw-drivers, thin and thick tweezers, cover from a box of CD (to keep sensor from dust), two boxes for parts and screws, lenspen
Glass preparations 7.5x8.5x2
Sandpapers for selfmade filter sides polish

Step #8
very gently please
(if modify this part - HV20 can read full size SD cards)

Step #9
These screws hard and long
Immediately put the sensor module under a CD BOX cover or similar for prevent from dust

Step #10
install prepared a piece of glass (clear it with Lenspen)
Gentle with tweezer remove IR cut filter and immediately assemble sensor module

Very Very Nice Work Garm!!!
FAntastic work and GREAT contribution to this forum, garm99!!
Thanks!

i must disagree... for the buck, this 6.1-61 does a great job!!!
calculating proportions of CMOS and Film, it's range equals a 35mm 28-280 lens... which is pretty flexible, and makes just excellent focus at surprisingly short distances... it surprised me, i must say!
of course... the idea of a prime 1.2f 50mm pointing light directly towards the CMOS, without having to loose light through camera's factory built in lens.. sounds kinda nice!

Could you upload the larger images onto this website? If you hit edit on your old posts, then advanced at the bottom, you can upload them (paper clip and attachment management). I'm unable to access the images on the .cc website where you have them. (Might require a login.)
Also, this should be helpful to those who wanted to paint the camera black or dark gray. I was thinking about it consumer cameras are silver, prosumer are often dark gray and pro are black (at least on my Sony cameras).
This is very helpful for those who wanted more detailed instruction on disassembly than Jerry Lee was able to provide in the flip hack section.
I'd really like to look at those bigger pictures though.
Thanks,
Duke
awesome thanks!
oh yeah painted black would be cool.. maybe some sort of new logo, like
hv20 AMG.. or MV20
or Canon Type R
lolz
OK
at soon i edit my old post for fixing large img links. Olso upload all photos without crops and editing in one zip file. Possible do it on ftp dot h20 dot info ? or rapidshare.com ?
you can ftp to hv20.

Yes, you can ftp to our own server.
Here's the official instructions:
Step-by-step instruction for free movie & picture hosting on HV20.info:
- you can ftp to hv20.info; the folder will automatically be chosen for you, just use "hv20.info" (without quotation marks) as the location
- use "anonymous" as login and password; without quotation marks of course
- max file size is 250MB per file
- NO COPYRIGHTED MUSIC PLEASE; do NOT use copyrighted music for your clip; it's not allowed unless you have permission by the author & the label
- please only upload HV20 related material; I'll keep an eye out for unrelated items and remove them
- use a free ftp program to upload, such as FileZilla on the PC: http://www.download.com/FileZilla/30...ml?tag=lst-3-7
- you need to link to your file like this: http://hv20.info/yopu/yourfilename.extention (example: http://hv20.info/yopu/hello.gif )
I, on the other hand, think it does a pretty good job for the price ;-)
I guess the main benefit of using C-mount lenses would be manual focus and F-stop settings?
on a second thought... the whole adapter idea is based in the current HV20's lens focusing the ground glass (or other 35mm sized surface)... remember, the HV's CMOS is about 8mm sized (1/3 inch): without camera's built in lens, you just couldn't get any way to focus on the ground glass!!! if you just bolt on 35mm lens, you WILL see only blurry stuff.
sorry for the off topic! won't happen again!
