and he said if you use a lens of a 35mm sensor on a DSLR with a smaller sensor it gets cropped !! FAIL FAIL FAIL WDC

[WhatDigitalCamera]

Let me clarify this for you. Nikon's DX sensor has a 1.5x magnification factor compared to 35mm, so putting a 50mm lens on a non-full frame Nikon gives you a field of view equivalent to 75mm on a 35mm SLR. Canon APS-C sensor has a 1.6x mag factor, so the 50mm would be equivalent to 80mm. 4/3rds cameras have a 2x mag factor, so a 50mm lens would be equivalent to 100mm.

It's a fact. Look it up.

[lorikzzz]

FAIL !! he said a 50mm is 75mm on a 35mm sensor

[WhatDigitalCamera]

No I didn't. Wash your ears out.

[orestisdeepblue]

you are wrong on the "noise vs many pixels" balance.

more pixels don't give higher noise levels per print.

[WhatDigitalCamera]

Yes they usually do. More pixels on the same size sensor equals smaller pixels, which have less light gathering power. Everything else being equal, the result is more noise which can only be reduced using NR processing. Obviously there are lots of other factors/variables that come into play, including the technology employed by different brands, so this is just a guide.

Thats why Canon reduced the pixel count of its G series camera from 14MP to 10MP to reduce the noise.

All this info is right.

I don't understand people criticizing this.

Absolute Morons they are.

Well done WDC.

Now you have a new directory of videos apart from news and reviews.

Nice Work

Thanks for the video guys. :D

Sir. with all do respects to the Gentleman of this video, as the MegaPixel Value, all know that the Resolution Increases BUT because the Pixels are NOW smaller, IT IS YOUR COLOUR ACCURACY THAT DROPS. Colour Accuracy is an Instrument Lab Photo measured as Color Accuracy,drops,to Compensate for this. Pro-DSLR Manufacturers increase the RAW from 12bit to 14bit, to 16bit RAW etc, etc, to give Each Pixel More Colour R.G.B. Data information. This directly impoves Colour Accuracy,increases Price too!!

I think you forgot to mention the APS-H sized sensor seen on Canon EOS 1D Mk4.

[orestisdeepblue]

The comment about the noise characteristics of the camera sensor is plain and simply wrong. And the fact that you haven't read why it is wrong is just stupid from your part. It's boring to keep on explaining why pixel-size doesn't affect the noise levels of the camera, just sensor-size does, along with the technology of the company that makes it.

@orestisdeepblue

um you're really not doing yourself any favours here. I'm not here to doubt whether you have read more than me.. but you certainly know less than me!! I love how people suddenly become experts on youtube when commenting on a video for amateurs in the first place. WhatDigitalCamera is 100% correct, there's no discussion. It's like you're trying to argue that 2+2=5. Just plain stupid.

[orestisdeepblue]

you should try that too.. i've probably read more on camera technology than all the people commenting this video combined

[prmass1]

Good review.

[hekta85]

You should try reading. This is very basic stuff.

[ascortjkk]

whats with these bastards here? anyway i appreciate your video its very helpful thank you :)
