Ok, I'm just an old man that has fallen in love with a so called Super Lens point 7 shoot camera. I take it everywhere I go, and take pictures of things most folks don't even notice. I am not willing to either lug around all the overweight and expensive equipment that an SLR would require to contend with the 20X lense on mine.
Why, can't some one put a larger sensor in a super'lens point & shoot camera. I am not so infatuated with huge pixel count, but I sure like the long lens capability of my now out dated Canon SX20IS. I have even learned how to take some pretty neat Macro shots with it and haven't dropped a lens in transition or worried about dirt on my sensor while changing lenses. Don't get too technical, just let me know why it can't be done. Thank Ye, One & All/

I think that you'll find that the Canon Powershot SX1 1S does just that. Here's a couple of reviews:

My SX20 is a couple of updates from the SX1 and both still have the wee little 1/2.3 mm sensor with CMOS upgrades, that make the SX20 such a fine performer, but it still does not do what an SLR size or even a four thirds sensor does for clarity and definition. The four thirds sensor is over twice the size of the 1 / 2.3 mm sensor.

I have an SX30is with the typical small CMOS sensor. I used to love the camera until I bought a 60D which has the APS-C size sensor. What a difference. The main problem with the small sensor "point and shoots" is the small aperture and degradation of the image quality due to diffraction (when light passes through a small opening). the SX30 only stops down to f/8. Now I know why. Comparative shots between the two cameras at f/4 or f/5 show the SX30 doing pretty well compared to the 60D but there is clearly a difference in resolution when shooting a resolution chart. However, at f/8 the SX30 image quality is significantly degraded while the 60D can stop down to f/20 or more with out any visible diffraction problems. The SX30 has a great zoom. If you keep it faster than f/8 you can still get some nice shots.

New Canon s100 for better sensor?

skwillard

Maybe better, but not bigger and that's where the difference is at.

skwillard

I know. That's why I wonder why a larger sensor cannot be put in the likes of an SX 1, 10, 20, 30 and etc. I just came in from taking fall pictures and some are pretty fantastic, but not anywhere close to what you will get with the one in your D60. Have Fun With It.

Not sure anyone answered your question if I understand it. I think what you want to know is "why can't I get a 20X point and shoot with a larger sensor?" I think the answer to that is that the bigger the sensor the longer the lense must be to get a given magnification. To get a 20X magnificaiton with a DSLR size sensor the lense would need to be several feet long.
Right?

Ok. Thanks.
