Title: Camera lenses question
Post by: jrebel on November 12, 2013, 02:34:37 PM: If a guy buys a DSLR camera and it comes with a 55-300mm lense, how much zoom does that offer? I am going to buy a DSLR and want a lense that I can take pics of wildlife at longer range so I need to start figuring this stuff out.

Maybe another way to ask the question.....will a 55-300mm lense on a dslr have a better zoom than my 20 power optical zoom on my digital point and shoot?

Thanks

Johnny

With most digital SLRs, a "normal" lens is around 35mm. That means a 35mm lens has a magnification of 100%: 1 to 1. A 70mm would be a 2x magnification. A 300 mm would be approximately a 9x magnification.

Don't get hung up on magnifcation. Primarily because of the difference in sensors, the image quality from a 300mm lens on a good digital SLR will far exceed the image quality from a compact point-n-shoot with 20x zoom.

I just got an e-mail from B&H photo, this was attached. It might give you some information. They have alot of tutorials on their website and a forum that may answer some of your questions too.

It's more a matter of size than quality.

I will always have lens envy, white, under F/4 or quicker, over 300 MM :drool:

I never thought I would say this... but short, stubby and fast (as in Macro) would be nice as well :chuckle:

Do all DSLR Cameras come with a crop Sensor?

No but most do. It will be listed as a "full frame" camera and will be significantly more expensive if not. They are targeted to professionals.
