Canon Lens Abbreviations and Acronyms
Lens manufacturers use abbreviations to specify the features of their lenses, and as the number of abbreviations increase with the newly added features, things become quite confusing especially for photographers who are not familiar with the lens technology.
In order to make things a bit more clear, we will present the lens types and abbreviations with descriptions in alphabetical order for the most popular lens manufacturers, starting with Canon.
AFD – Arc-Form Drive: An older type of in-lens AF motor like USM but slower and noisier.
AL - Aspheric Lens: A special design lens used to minimize aberrations. Aspheric lenses can be designed more compact and lightweight then conventional lenses.
CA – Circular Aperture: Canon lenses with multiple aperture blades shaped to give as circular an iris shape as possible, effects the bokeh.

Dirt on your DSLR lens is one of the main factors that reduces the image quality of your photos. Although some defects caused by small spots may be repairable in post processing, larger dirts most probably will probably make your photo useless. Even a tiny stain that you haven’t noticed or ignored during the shoot out can ruin hours of hard work at the end of the day. The most important fact that you have to consider before cleaning your lens is to choose a proper method to make sure you don’t scratch your lens surface.
Here we present 6 tips for you to effectively clean (and keep clean) your DSLR lens without giving any damage to it. Remember most of these methods presented here are also applicable to compact digicam and other kind of optical devices:
1 - Use a UV (Ultraviolet) Filter
This relatively cheap filter is a perfect protection for your valuable lens, both from dirt and other impacts. You will be cleaning the filter, thus minimizing the risk of scratching the actual lens surface. We recommend you to keep this filter attached all times, but remember to choose a high quality one otherwise it may degrade the quality of the output image. Since different lenses may have different filter diameters, you may have to purchase one for each of your lens.
UV Filter
2- Use lens hoods, and lens caps for both front and back end of your lens:

Nikon finally released the official D3 sample photos, ISO ranging from 200 to 6400. Low light performance of this beast was what everybody was waiting for, as that will be the decisive factor for many pro photographers. As we have seen from the sample photos, high ISO image quality of Nikon D3 is stunning. New full frame CMOS sensor of D3 seems to be working very well.
All sample D3 photos are taken with AF-S NIKKOR 24-70mm F2.8G ED except one which is taken with Ai AF NIKKOR 85 mm F1.4D.

Introduced in August of 2005, Canon EOS 5D has been the "budget" full frame DSLR with its astounding image quality and high ISO performance, even outperforming the 16.7 MP flagship of Canon: EOS 1Ds MarkII in means of image quality according to some photographers.
Now EOS 5D is already 2 years old and the competition is getting stronger, especially with the new full frame introduced by Nikon: D3. So as many agree, 5D is due to upgrade very soon. The new name is likely to be EOS 5D Mark II, altough it is not out of possibility that Canon may name the new as a new series like 3D or 7D.
The photo below is claimed to be the new Canon EOS 5D Mark ii, although we can not confirm if this is real or not since we came across several 'photoshopped' images before: |

Zena Holloway
An ultimate and boundless creativity. An arduous passion. These may be the most suitable words describing underwater photography. You need more light, more equipment, more concentration and ofcourse more breath. It sounds like a kind of torture to me but as to Zena Holloway it’s a lifestyle. |
