Sigma Lenses For Canon Slr
For those of you who want to know what these abbreviations are in the process, I compiled a list of terms used, what it represents, and of course what she really can do for you or to avoid.
Abbreviations General.
Before getting into the nitty gritty of why they are all different, look at the commonalities. There are three common terms to describe the objectives for SLR cameras and they are easy to understand and relate exclusively to the functions of creation and performance.
Focal Length: – The scope of the scene captured by example 16-35mm. A goal which covers an area of 16 mm (relatively wide) 35 mm zoom.
Max Aperture: – The maximum speed at which the lens can pass light. For example, 2.8 or f3.5 – 5.6
If the target is a unique number, so it maximum aperture possible.
If the lens has two numbers, then there are openings greater potential depends on the lens focal length is established.
The higher the number, the greater the lens opening and the faster it allows light. (See my forthcoming paper on the law of reciprocity)
AF / FF: Switches between autofocus and manual focus

USM ultrasonic AF motor. Two types. USM micro direct replacement for older systems in the engines of FD and the USM with manual control.
NE: diffractive optics. A technology that allows Canon lenses produce shorter physical distance.
TS-E tilt shift lens to correct the perspective in the image usually a modified architectural converging lines and depth of field. Similar to "Sinar" of the camera.
The goal Canon professionals with superior optical quality and functionality are not specific. As usually white. All L-series lenses have a red ring on .. out
MP-E Macro Photography Electronics. Lenses designed for macro with the opening of an electronic control function.
IS: Image Stabilization, a system designed to reduce hand movements. version Nikon is called VR (Vibration Reduction) and Sigma is an OS (optical stabilization).

Hi, my name is Keith Trigwell. I’m a live music photographer and I also have a passionate interest in most other types of photography, particularly portraiture and Fine Art. My live music shots can be seen at http://www.flickr.com/bigmojo
To pass the time I also write a few articles on photography and technical photographic matters.
SLR Camera … Questions?
I got an old SLR film camera with Praktica Praktica BX20 objective lens and a Sigma. Will I to buy an adapter to use these lenses in my new Canon 450D? Thank you for your help!
Its new Praktica has been made in 70s when he was prolly still in Jr. High – I would have loved to have * – I used a bellows camera and an old Graflex Graflex camera. The meter is working? * Is * Have a light meter? You can keep your Prakica as "high risk" situations – like a boat ride or something, where has been dropped, wet fly, so there is no great loss.
