The Best Camera?

A Bridge Camera is not a DSLR and are not a patch on them.Here is some info on both. You are better of with a DSLR ..........Ron

LCDs and EVFs as principal viewfindersBridge cameras employ two types of electronic screens as viewfinders: The LCD and the electronic viewfinder (EVF). All bridge cameras have an LCD with live-preview and usually in addition either an EVF or an optical viewfinder (OVF) (non-parallax-free, as opposed to the OVF of DSLRs, which is parallax-free). A high-quality EVF is one of the advanced features that distinguish bridge cameras from consumer compact cameras.

All DSLRs, by definition, have a through-the-lens OVF. Newer DSLR models typically also allow 'live view' on the LCD screen as an alternative to the OVF.

[edit] Live-preview EVF advantages

The EVF of bridge cameras, and the LCD of bridge cameras and DSLRs in 'live view' mode; continuously show the image generated by the sensor. The continuous digitally-generated live view has some advantages and disadvantages compared to the optically-generated view through the OVF of DSLRs. One advantage is that the digital preview is affected by all shooting settings and thus the image is seen as it will be recorded (in terms of things like exposure, white balance, grain-noise, etc.) which the OVF of DSLRs is incapable of showing.[11] Another advantage is facilitating the framing from difficult angles by making the LCD movable (vari-angle). The LCD and EVF normally show 100% of the image while previewing (WYSIWYG). The OVF of professional DSLRs normally shows 100% of the image, but the OVF of consumer DSLRs may show slightly less than 100%.

[edit] Live-preview EVF disadvantages

The electronic screens of bridge cameras do not work as well as the OVF of DSLRs in situations of low light, or in bright daylight where the LCD screen might be difficult to see and use for framing. Also the screen has low resolution and refresh rate compared to the very high resolution and instantaneous refresh provided by an optical path in the OVF of DSLRs. Low resolution impedes manual focusing, but most modern bridge cameras implement a method that automatically magnifies a central frame within the screen (manual focus point) to allow easier manual focusing. A slow refresh rate means that the image seen on the screen will have a fraction of a second lag or delay from the real scene being photographed. The electronic screens used in modern bridge cameras are gradually improving in their size, resolution, visibility, magnification and refresh rate.

Continuous operation of the sensor shortens battery life and raises temperature. A DSLR's sensor (when not in live view mode) only operates when the shutter is open, and the electronic screen is typically off more, causing less battery drain. In bright conditions the light impinging constantly on the sensor of a non-SLR so it can show the image can heat the sensor, increasing image noise; in a DSLR, the sensor is exposed to light only during the fraction of a second that the shutter is open.

@Ron Tao&Sky Interesting. Never thought of that.

For those who don't know all the terms: Bridge and DSLR cameras have viewfinders. Most compact camera don't have these any more these days. DSLR have an optical viewfinder (OVF) that uses a set of mirror to let you see what the cameras sees. It's the way all old cameras used to work.

Bridge cameras have an electronic viewfinder which means it still has a viewfinder but instead of looking directly through the lens, you're watching a mini LCD-display inside the camera. This display will give you a better idea of what the image will look like when you shoot it but as said, lag, the low resolution and battery usage also make it a bit harder. I know of experience that as soon as you find yourself in a bright sunny day, this display becomes much harder to see.
