p.1 #1 · What are the limits of a pocket-able camera?


I am an enthusiastic owner of the Sony RX100. There is little dispute that this is currently the overall best you can get in a jeans-pocketable form factor. Other compacts like the LX7 might have brighter lenses, but it does not adequately compensate for their tiny sensor - not to mention being bulkier.

I'm wondering what more can camera makers do within the confines of this form-factor. I'm guessing that they still might be able shave off 1-2mm from the LCD using the latest (or near future) ultra-thin display tech, so they can use this space for a slightly better speced lens, but I'm thinking that the only potential improvement might be a overall brighter lens at the cost of lower zoom range.

For example a 28-75mm F/1.8-2.8 lens with the RX100's sensor and size? Would this be realistic?

While I am an RX100 owner, I won't say that LX7 has a tiny sensor.

Normalizing for the sensor size difference, LX7 lens is equivalent to around f2.3-f3.8 compared to the f1.8-f4.9 for the RX100. So it more than compensate for the smaller sensor on the long end. However it is indeed bulkier.

The current RX100 lens is f4 at 75mm. It might be possible to give up a bit of the range and do a bit more engineering to do better than that. Then there is always the tradeoff about how much quality you are willing to give up. These extreme designs are typically made possible by relying on software correction for lens aberrations (which is not necessarily bad if the end result gives you the quality you expect)

Give it a year or less. Someone will figure out a way to blow your mind again.

Yeah, I'm waiting for Casio to hit again. Maybe 1,000 fps on a nearly 4/3 sized sensor plus all the other crap these little cameras pack in.

Limit is how much people are willing to pay for such cameras. I'm sure if price was no object it would be possible to make something like a RX10 with a 35mm f1.4 fix lens, semi build into the body, take all the care possible to minimize distortion etc, tweak the sensor etc.

Be a really cool camera and I'm sure people on this forum would buy it, but would consumers as a whole ?

$1799 for a 1" sensor fixed lens "P&S" style camera ? Probably wouldn't sell enough to make it profitable and that is what its really about

Its not pushing technology or making the best camera, its what is going to promote the brand, increase profits etc.

how about an awesome performing collapsible prime that is fast and can really use all the pixels on a 20mp+ 1" sensor. maybe an even bigger sensor too?

Casio? Are they still in business? I thought they collapsed into a heap years ago.

Not that i know of.
http://www.casio.com/products/digital_cameras/

I think the current EXILIM high speed camera is still the Jan/2011 version tho with;
FHD: 1920 x 1080(30fps), STD:640 x 480(30fps)
HS : 224 x 64(1000fps) / 224 x 160(480fps) / 432 x 320(240fps) / 432 x 320(30-240fps)
movies and
40fps, 30fps, 15fps, 10fps, 5fps, 3fps
still frame continuous tho.

I'd like to see a 4 or 6 megapixel 1,000fps mode.


They release every January or so and released 4 compacts this year (that I know of). I dunno what's up for 2013 tho.

+1
1920x1080P @1000fps would be fun.

oh you can have a full frame camera with an optical viewfinder, a rangefinder and a nice 35mm/2.8 lens
It's been available for the last 30 years, will set you back about $40

anyway I wasnt just trolling with the XA, I posted the photo to show that the main problem is the inability of larger digital sensors to deal with lenses that sit very close to them. Solve that problem relatively cheaply, and you get a massive improvement what can be achieved in terms of sensor, lens and camera size, as that little XA shows.

IMO digital technology gave us ease of use, image quality and consistency, but in every other aspect of camera design it took us many decades back. With film, the OP's problem was already solved in the 70's
