Camera lenses question
« 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

It depends on the sensor in the camera, which in turn determins the crop factor.

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.

Thanks for the information.  Do they make DSLR bodies with better sensors or are they all relatively the same?

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.

My longest lens is a 500mm and I wish I had twice that much.  I think the key to getting quality wildlife photo's, and I think the pro's on here will tell you the same, is to get as close to the subject as possible.

Do you ever really have enough lens  :dunno:

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:

50mm is equivalent to your eye and is 1x.  300mm would be 6x.  with a crop sensor camera, the image produced would be equivalent to 480mm or almost 10x.

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.
