I think the best bet will be for the f/1.6 lenses. I had good experience with them. If we can all agree on a focal-length, that'll be the big hurdle. The understanding is that we'll get the best f/number we can for around $10 to $15 each lens.

please add me on the list for 2 or 3 lens
thanks

add me for a lens
the postage from ebay rips the a ss out of it

what about the car adapter? No more of those? IMO, for the car, it was a little better than the battery since it doesn't require recharging, although the cord was a little annoying

I just got my lenses in the mail from (GESS) ebay yesterday! The camera is amazing! I got a 2.5mm F1.4, 2.8mm F1.4 (this one though I will have to adjust by backing out the two black screws in order to get it focused), and a 4mm F1.2 lens. the 2.5 and 4 looked great immediately. Yeah, ebay shipping does suck for something like this thats why I bought three lenses. I'm not sure which one I like best though. Wouldn't these be better than F1.6 (the ones youre trying to get) Mark?

the shipping was ok to the states but was $20 to the uk
much more than it would have cost

Also, I thought it was responding to my input without pin4 being tied, but it wasn't.. I have it tied to 12v now, and its displaying image (like you see above) however I'm having trouble getting it to display properly.. an odd thing is that pressing the GAIN button on the LCD actually causes the image to stabilize on the vertical axis

So GAIN being active fixes the vertical rolling? Have you tried probing around with a multimeter to see what's the different with it on vs off? You might not be able to get enough info from a MM, but it's worth a shot.

Does GAIN being active actually effect the look of the screen when inputting a signal this way?

Hey Greenman,

Count me in for a lens. Not really too picky about any specs, just prefer a wide angle of some kind.

Thanks!

I have researched this by studying the documents we have. I think there's a simple cure!

Here's where Vertical Sync needs to go. I understand the circuit but I don't know what polarity you've got or what polarity the LCD Controller expects.

I'd like you to try touching your VSYNC signal to this point on the resistor where I've shown. This is where VSYNC needs to ultimately reach!

So, I connected the H sync pin from the VGA connection to the composite sync input...

The result is an image which is PERFECTLY stabilized horizontally.. it looks terrific... the only problem is, it slowly scrolls vertically =\

This is the screen running at 640x480@60hz (no special timings).. now if I can just figure out how to get it to stop slowly rolling. :P

Fusion-One · 03-30-2006, 03:59 PM

I gave that connection a try, but it doesn't solve the problem, unfortunately.. IT is definitely in the right area, though. When I intitally connect it, it causes a vertical shift in the image to a random position on the screen, and then continutes to roll.

An error I made earlier, when I thought I was outputing 60hz vertical to the screen, powerstrip was still controling the refresh rates (windows rates were disabled) so while I thought it was eating up 60hz, it was actually taking in a touch under 30.

Still scrolling. :P

(Notice how readable that text is?? 640x480 on a 2.5" screen, and its actually readable! (The insanity!)

Yes, f/1.4 should be better than f/1.6. I found that the f/1.6 lenses worked better than the number predicted.

Would you mind posting a picture of these lenses? I'd like to see how big the actual lens on the front is and how tall the whole lens body is. (I don't trust the pictures in the auction listings because I've noticed that some of them are wrong!)

For a given focal-length (like 2.5mm) the lens with the larger glass area should have a better f-number. I'm wondering if yours actually have bigger glass glass than the ones I've seen.

Here's my vote for a decent lens (f/1.4) that most can afford (~$10.00) and it is adjustable to accomodate different needs. (3.5mm - 8mm)
