[WIP] Attaching an SLR lens to my N900
 

I decided for my next time waster, I'll be attaching a Nikon SLR F mount to my N900. I wouldn't trust the flimsy plastic case to hold a lens without the whole back cover falling off, though. So first step's first: Make a new back cover.

Great idea!
wish you lots of patient with that speaking from my experience :D

It reminds me something i did a while ago.
sorry if its off topic just to share
Took me quite some time to make it work and fit.

O nice. When mine is done the OEM lens will be taken out, too. Hotswappable would be nice, but I don't think I could do that.

@azkay:
Very interesting, eager to see results.

@ed00
It looks amazing, could you post more technical details - how you've decided to do mounting, alligning focus, and maybe some example photos (of same object with or without zoom, like I did with my proof-of-concept 10x zoom for N900)?

You do of course realize that the crop factor of the N900 sensor is something around 6, which makes 35mm lenses pretty unusable for any normal photography barring possibly birdwatching?

In other words, if you fit in it a normal objective like Nikkor 50mm/1.8 you get equivalent FOV of 300mm.

I realise "I decided for my next time waster".

Now I need a way to attach it to the body.
I would screw it on, but I need somewhere to screw to.
If I had longer screws that fit the N900 I could use the four corner holes.

Either way, until I get DSLR parts I now have an ironmanesque cover.

One question - why not use a real Nikon lens mount? I took a look at my D90, and its mount looks about the same size or slightly larger than the N900.

If I didn't have a CNC machine to print out a full back cover I'd salvage a real mount off an old AF-S body. That way, you get the real feel and "click" of the mount.

I am using a real Nikon lens mount, I just don't have one yet. I'll have it screw into the metal case.

Nice project, good luck :)

any progress ?



how to manage this lens (intex webcam) working with n900?

Re: [WIP] Attaching an SLR lens to my N900
 

Progress has stopped until I get the parts and find a way to attach the case.

On a different note, I bought a Nikon D5100 and two lenses, so once I get the mount I have glass to test with.

i tried intex webcam lens (posted image). not succeed.

Re: [WIP] Attaching an SLR lens to my N900
 

This seems like a typical S-Mount (M12x0.5mm) lens. Most of those assembled to webcams are crap (cheaply built, not applicable for megapixel resolutions) and probably not well-suited for 1/2.5" 5MP sensor anyway.

Try http://lensation.de/cms/index.php?op...cchk=1&lang=de or http://www.lechner-cctv.de/board-cam...-5-.75.en.html
to evaluate some of the better ones.

@ Letsee

My goal was to come up with simple solution and zero impact/damage to phone. So i managed to fit the washer that came with Fish-eye lens under slider/cover but had to significantly reduce thickness of washer to fit in that gap and got to be very careful not to damage slider/cover. And easily open and close it. Washer has a sticky glue on another side. It attaches strong enough to the surface (see pic.) Fish-eye lens has magnet-ring (see pic.) by cutting body of Lens to tight fit in to opening (obviously the more precise you are the better it fits). To cut aluminum body and portion of magnet ring i used a diamond disk. Probably picture quality could have been much better if i bought better Lens (this one cost me just $15) Lens gives almost 180° (see pic) Well after all this was just an experiment to see how will it works out. Im pretty sure its possible to improve it. Need time and efforts :)
