7. Why might you choose to use a wide angle lens to shoot portraits instead of a telephoto lens?

You can zoom out and isolate the subject better from a cluttered or busy background

The wider lens tends to flatter most people

None really. These are vastly different cameras bought for different reasons.

Whilst I wouldn’t immediately recommend any of our ILCs as Olympus does not have models that are direct alternatives, I'd mention that many hobbyists who purchase full-frame DSLRs, and who can afford to, have good reasons to purchase an OM-D model as a walkaround/travel alternative. Full-frame SLR camera owners are some of the best customers for an OM-D and our fast prime lenses.

The E-M1 obviously. It offers similar imaging performance and has tremendous other advantages over these two models.

74. What are the 'disadvantages' of a "full frame" sensor camera system compared to an OM-D based camera system?

There are no disadvantages. This is the best camera solution that money can buy.

Generally, the bulk and weight of the camera system; therefore its low portability and high physical demands on the photographer

Most suffer from the dust problem – which means the inconvenience and added cost of regular maintenance to remove sensor dust; and the need to be much more careful in changing lenses to prevent dust spots

The overall cost of system ownership. For instance, high performance lenses for full frame cameras are proportionately a lot more expensive compared to similar lenses for ILC systems like the OM-D

Many high performance lenses for full frame camera systems have no image stabilisation, making handheld photography more challenging

83. The advantages of the 4/3 sensor over an APS-C sensor in camera system design are:

The overall camera system can be made smaller, making the camera body, lenses and accessories easier to carry around

It makes it easier to incorporate IS technology into every camera body regardless of price, thereby ensuring that one of the most important image quality determinants is available with any lens used

The performance difference between a slightly bigger APS-C sensor is not overly significant
