    I finally bought a 50mm 1.8 again. I used to have a 1.4 but couldn't justify the price for how little I carry an SLR around.

    Casio had their credit card sized cameras a few years back, probably more like 6 years back. Anyways, they relied on a periscope style setup to give full zoom with moving lens elements in a thin package. I'm actually shocked phone makers haven't looked into that tech. It had its share of optical issues since there was a light redirection, but the average person would never notice.

    I've always dreamed of a 1.4 ... but as you say, way too pricey..

    As far as movable lenses in phones, I think there are two main issues, on of which is durability. Its a phone, it will get dropped a dozen times per year.. even small drops might mess with the alignment. The second one is the fact that they need to use small sensors, and when you close the aperture further with a zoom lens there is even less light reaching the sensor.. we loose quality, there is just not enough there to compensate for it... not at 1.4 microns, and not with the current crop of sensors.

    Also.. You have to use glass.. which is heavy. The optics in the 920, N8, and the 808 are all plastic.

    Nokia did try an optical zoom system a while ago.. long before anyone else.. it was the N93 and the N93i

    "The Nokia N93i features a 3.2 megapixel camera, Carl Zeiss optics, 3x optical zoom and digital video stabilization."

    Nokia N93 - Wikipedia, the free encyclopedia
    Nokia N93i - Wikipedia, the free encyclopedia

    That was 6-7 years ago..

    So I think that was why they had to figure another way of zooming without any moving parts.. which is what we have in the 808, its pretty much based on satellite imaging... where they have an image with huge resolution, and then they crop out a section of it to "zoom" in .. its exactly what happens with the 808.. it takes a 41Mpix image, and it crops out the middle of the frame in real time.

    Anyway, I think we can all agree that 920 has a great camera. I rather just enjoy the camera rather than getting into all this tech talk but there seems to be a lot of misinformation and mischaracterization in this forum. But that probably happens for every phone cameras.
    Better cameras bring out the enthusiasts and pros among us, which I love. My only gripes about the camera are the dynamic range (the one thing I wanted from the 808) and the disappointing camera settings. I've said it before and I'll say it again, but if someone developed a camera app made with enthusiasts/pros in mind with manual settings and settings in general that required less taps to get to things like color temperature adjustment, I'd pay. I'm thinking part of the problem lies with Windows Phone itself, but that's just a guess. When Nokia figures out how to pack the 808 sensor into a device the size of the 920 with OIS, I'll buy it.

    ^ the 808 has a very.. strange dynamic range.. I would say its weak. People say it suffers from "highlight clipping" but I still don't get how that is different from a weak DR. Whatever they did, the pixel oversampling can go only that far... I think that the weak DR basically exposes that after all, the 808 shoots with the same tiny 1.4 micron pixels like most other smartphones.

    No.. its this one: Amazon.com: Tamron AF 28-75mm f/2.8 SP XR Di LD Aspherical (IF) for Canon Digital SLR Cameras: Camera & Photo

    I think its a bit better than the kit. I also have this one: Amazon.com: Canon EF 50mm f/1.8 II Camera Lens: CANON: Electronics

    The last two pics in the album are with that one.. very narrow on a non FF dslr, but it still works great for close ups, great bokeh.

    Don't get me wrong, the dslr is still better ... but it all depends on your usage. Personally.. I really don't need more than the 808 for the most part.

    So considering that they have the technology ready to go (optics + sensor) I expect a device with the same system running on WP very soon. Hopefully MWC in February.. that is where they announced the 808 this year, and then it took them about 3-4 months to ship.
    That's a really good lens. I have it as well.

    This is apparently from Nokia's Juha Alakarhu:

    "Aperture refers to the iris in the lens and how open (or closed) it can be when taking photos. When the iris is opened to the max, it results in a lower F-Stop, which on the Lumia 920 is a F2.0. The more open the iris, the more light it lets in, which is what we need for low-light photography. The downside is a lower F-stop results in a softer image with less sharpness."
