Pros and cons of being able to change the lens on a camera

Question

what are they?

Answer 1

Pros:

- The ability to swap lenses allows you to modify your camera to best capture your vision, whether it be artistic (wide angle, telephoto, bokeh etc.) or utility (speed, weight, size, etc.). To me and many others this pro outweighs all cons which, coincidentally, stem from this pro.

Cons:

- Dust on your sensor. This isn't that big of an issue now with dust reduction systems and cleaning tools but it's still a reoccuring problem for some.

- Hassle for casual shooters. You'll rarely find a pro or advanced amateur who complains about the actual activity of swapping lenses.

- DSLRs are expen$ive. Lenses are expen$ive. Accessories are expen$ive.

As you probably noticed, there are no cons that regard the actual intended functionality of a camera: taking pictures. Interchangeability gives you access to a near-infinite assortment of quality lenses -- assuming you have the money for it. If you can think of one it's probably poor technique over anything else.

Answer 2

Professional photographers have to be able to use many different lenses in the course of their assignments.

For that reason, a truly professional camera system will include lenses from extreme wide angle to extreme telephoto prime lenses as well as specialty lenses which include fisheye, perspective control, macro and zoom lenses.  The ability to use one camera body that accepts any and all those lenses is paramount when a professional chooses a camera system.

In the shadow of the professionals are those who are semi-professional, that is that some of their income, but not all comes from being a photographer and behind them are students and advanced amateur photographers ... all of them use fully adjustable cameras with interchangeable lenses.

Since the only cameras that have lenses that are permanently attached to the camera are the P&S variety, there are many reasons that any of those who typically use SLR or DSLR camera systems cannot use them to make a living with them.

1) They have tiny sensors

2) The lenses are not only restricted to focal ranges that equal a medium wide angle to long telephoto reach in the form of a zoom lens, the cameras are mostly automatic and do not give a photographer the full control such as selective focus, aperture and shutter speed modes, control of remote flash units from the camera, rugged construction and other special features pros depend on day in and day out.

3) The ability to upgrade the cameras technology without having to replace the lenses and other accessories associated with the camera system

These are just a few of the reasons to own and use a SLR or DSLR

Who knows, who cares.
