Can someone explain to me about this Full Sensor stuff?

[WesVFX]

I just can't seem to wrap my head around a full sensor and it's advantages.

A "Full Sensor" is physically larger than a "Crop Sensor".

Long story short...... better image quality.

The good stuff is full frame.

bigger sensor = bigger pixels = less noise, with everything else constant.

Take a photo and put a thick border around the outer edges and what you see is what you'll get with a cropped-frame sensor...take the border off and that's what you'll get with a full-frame sensor...or just take an old 35mm film camera and take a photo and that's what a full-frame digital sensor will capture as well...imagine a small window into your house...lets a little light into the room...imagine a much bigger window...much more light into the room...

The downside is they are more expensive and your long lenses won't be as long. Also, your lenses will show more defects around the edges of the frame than they would on a crop sensor. Expensive glass is more beneficial on a full frame than on a crop. A benefit other than the ones mentioned above is that wide angle lenses are even wider.

It's all a matter of perception. Another way of looking at it is this:

Take your FX-size sensor camera and put a 200mm lens on it. Now change that to a 300mm lens. The difference in the field of view is what you will see when going to a DX sensor since you get a 50% increase in effective focal length. FX may arguably have better image quality (emphasis on "Arguably", depends on the camera) but, in my opinion, at the COST of a loss of 50% of your focal length.

A lot of what I shoot needs all the reach I can get and while I have thought about going to a FX sensor camera I'm not sure I'm willing to give up 50% of my focal length.

You're not giving up any focal length. A 200m lens is a 200mm lens, whether it's on a full-frame or crop sensor. The lens doesn't know, nor does it care, what camera is behind it.

What you're really "giving up" 50% of the image the 200mm lens produces.

I didn't say that you were. What I said was:

If you put a 300mm lens on a FX sensor camera and a 300mm lens on a DX sensor camera the DX sensor camera is going to APPEAR to have a longer lens on it because the image is being cropped on the sensor.

Should I buy a Full Frame DSLR?

Fair enough ... I omitted the word "Effective" in that line.

If you are worried about the loss of focal length, crop your image.
