35mm APS format

Have you heard of the 35mm APS format camera? Most of the DSLR actually apply this kind of image sensor in them and thus the name. Read more after the jump.

• The APS actually stands for advanced photo system image sensors. The sensor has an aspect ratio of 3:2.
• This type of sensor are used in many digital single- lens reflex cameras (DSLR), a few large- sensored live preview digital cameras (Sony DRC-R1, Sigma DP1 and Leica X1) and a few digital range finders.
• The APS system is subdivided to the 35mm full frame, APS-C standard and many other more. You can see the difference between them in the image below.

Image sensor size
• The APS-C standard have a crop factor ( focal length multiplier) to calculate the 35mm equivalent focal length. The normal crop factor used is 1.6x.
• Most DSLR and third party lens manufacturers have lenses specifically designed for APS-C cameras. The brands include: Canon, Nikon, Sony, Tamron, Sigma and others.
• Do you know that DSLR is a digital camera that uses a mechanical mirror system and pentaprism to reflect the light from the lens to the viewfinder.
• DSLR are considered better than point and shoot camera because you have more control over your photos as in you can choose different settings for your camera.
• Last time the point and shoot camera win over DSLR as it has live view mode but nowadays DSLR also have the live view function already.
• This type of sensor are used in many digital single- lens reflex cameras (DSLR), a few large- sensored live preview digital cameras (Sony DRC-R1, Sigma DP1 and Leica X1) and a few digital range finders.
• Recent DSLR also have the high definition function and are able to shoot high quality videos too.

The advantages of APS-C DSLR over full frame is that APS-C DSLR are much cheaper than full frame and usually lighter and smaller too. The downside for APS-C DSLR is that full frame cameras are able to take better quality image. The crop factor of the APS-C also cost the focal length to be bigger by about 1.6 which means a 200mm lens behaves like a 360mm lens.
