Dear friends. Thks very much for your support and valuable information. This encouraged me to ask more questions.,
Which model is d entry level RX model in Canon. How much does it differ from Canon 70D in image quality and performance. Does it have an edge over Nikon's entry level RX camera.

Not sure what an RX camera is.

"Does it have an edge over Nikon's entry level RX camera."

Nikon has a DX and a FX model. Is that what you are meaning?

In a Nikon, the DX is similar to the Canon 'crop' cameras like the Rebel series. The FX is a full frame camera similar to the Canon 6D and 5D Mk III.

Sony has an RX camera. It is a point and shoot. The top of the line Canon is the G1x Mk II.

Model for model cameras, the Nikon and Canon are very similar. Nobody but nobody has the lens line up that Canon has. And the lens is where it's at.

If you live in the US (I don't) and your hands aren't too big you may want to check your local WalMart for a Canon SL 1. One of the forums I follow says WalMart is clearing them out at $299 & that's with the 18-55 kit lens. Very good entry level camera well below the usual price.

Dear Mr Cicopo,

Thank you for your patient hearing. I live in India. I mean which is the Canon's entry level full format camera. Whether Canon 70D is a full format camera. WIll there be marked difference between a full format camera and crop camera in image quality except for low light photography. Whether Canon 70D can perform better at low light??

I mean full frame camera. Whether Canon 70D is a full frame camera? Whether a full frame camera will have marked difference in image quality than a crop sensor camera except in low light photography??

Hi Pkbiswas.

The entry level full frame camera is the 6d. I have one and I love it.

The 70d is not a full frame camera. It has a smaller "cropped" sensor.

Yes, the EOS 6D is currently Canon's entry level full-frame DSLR.

All things being equal, one of the biggest differences between full frame and crop sensor cameras has to be depth-of-field. Give each type of camera the same angle-of-view at a subject, and the full-frame sensor will have a shallower depth-of-field. In other words, an 80mm lens on a full-frame sensor can give you shallower DOF than a 50mm on a crop sensor.

1.) "Low light" conditions are very common, so the low light advantage is not a small thing. Keep in mind that "low light" to a camera is not really all that low. Your eyes are way more sensitive to light than a camera is, and you can see fine in light that will make your camera struggle. Indoor lighting at night time can often be low light to a camera even though you can see just fine with your eyes.

2.) Grain, noise and lack of detail are what you have to deal with in low light. When the camera needs more light, and you have already opened up the lens to its largest aperture opening size, and you are already using the slowest shutter speed you can use without getting blurry pictures, then the only thing the camera can do is to raise the ISO, which is the light sensitivity of the ~~lens~~ sensor. Unfortunately this carries a cost, in that it lowers the image quality in two ways. First, it creates "noise", which appears as grainy and/or colored little splotches. Second, at high ISO the camera captures less and less detail. Especially if you crop the image in post processing, or if you have a large monitor, you will notice the image is kind of blocky and things like facial features (eyes, lips, etc.) will have a weird low resolution quality, and you may not be able to see fine details like eyelashes as well as you could at lower ISO settings.

(At this point someone on the board may find the urge is nearly irresistable to post one of their photos shot at high ISO's that looks OK, and may question my technique, or question the reliance on what you see in a big 30" computer monitor instead of what you would see if you made 8" x 10" prints of everything instead.) 🙂

The larger pixels in the typical full frame sensor give better image quality at higher ISO's. Up to about two stops better, which means when you have to raise the ISO setting in low light, the full frame sensor will give equivalent image quality to a crop sensor when the full frame is shooting in 1/4th the light. For example, an image shot with a full frame 6d set to ISO 3200 may look as good as an image from a crop camera set at just ISO 800.

This is very approximate, and the exact numbers will vary depending on what cameras are used. Some of the new mega high MP full frame cameras have to use pretty small pixels, so the advantage erodes a bit.

As I understand full frame camera has a bigger sensor hence works very good in low light condition. Does it mean that it will produce good image quality indoor with normal lighting without using a flash??

It might. It depends whether you find the extra noise the high ISO setting adds to the image objectionable. As always, your mileage may vary. Even with my APS-C rebel, I rarely use flash and the images come out pretty well.

Still subject maybe, moving targets not likely.

Good point.
