Tokina AF 10-17mm Fisheye DX Lens Canon-Nikon Review

www.microglobe.co.uk Sharpness isnt a prime concern in this type of lens of course, but with the Tokina 10-17mm fisheye Ive got no complaints as far as sharpness goes. Distortions, well whats the point of talking about that, its meant to be distorted so its no bad thing this time. I really like this little lens, its well made and lets me take unusual shots that can be highly appreciated by the couple. Its not a lens that should be added to your bag when first starting out as there are probably several others youll need before getting to unusual lenses that will not be used often like this. If you are looking for a fisheye though, I think this Tokina 10-17mm is a great, unique piece and well worth a look.

EF 35mm f/2

Read More Full Content...

I bought this lens because I wanted a good, fast prime lens for indoor use on my 50D. I also own the EF 50mm f/1.4 which I love, but indoors I find it less useful due to the crop frame sensor of the 50D.

I knew I wanted something in the wide angle range (due to the 1.6x crop frame of the camera) so I looked at the EF 28mm f/1.8 USM and the EF 35mm f/2.0. Based on reviews here at Amazon as well as outside websites I decided to go with the 35mm f/2.0 because the 28mm seems to have consistently negative reviews. I was also able to pick up this 35mm for about 0 less than the 28mm so it seemed to be a better investment.

I have now had the 35mm for about 1 month and taken over 300 photos with it on my camera. All in all I am happy with the lens and it has been on my camera nearly the whole time I have owned it. The images are sharp and the color is good. This is a fast lens and you can get some great bokeh when you open it up wide which is nice when you want to get creative with your photos.

However, I am more than frustrated with the auto focusing with this lens. It does not seem to want to focus on the subject of the frame, many images end up out of focus if I let the camera do all of the work. When left to its own devices, many times this lens will not produce images that are in focus, or at east not what you wanted in focus.

The only way I can get the great photos that this lens is capable of is when I take control of the focusing points and select exactly what I want in focus for each shot. This is not overly difficult and I am used to it because I am generally selecting the desired auto focus point for each shot, but this lens seems to be abnormally challenged at focusing on the desired subject on its own.

This has been a major disappointment because unfortunately I know that when someone else (who is not familiar with how to use the camera) picks it up it is 50/50 whether the photo turns out, especially in low light situations.

I feel that this is a problem if you are looking at this lens to be a good all around indoor prime for candids and family shots and especially if you want to be in some of the photos.

This is a good lens if you are familiar with how to use the auto focus selectivity features of your camera. The image quality is good, similar to the 50mm f/1.4, and definately better than any kit lens you may have, but don't expect to put this lens on your camera and never have to learn how to really use it on your camera.

Canon 70-200 L Lens Review


Image : http://www.flickr.com


You bought that DSLR for the versatility and ability to change equipment to handle any and all situations. There is one piece of equipment you don't want to leave on the shelf. It is the Canon 70-200mm L lens.

There are actually four of these critters, and there is plenty of discussion about which is the best. But the truth is that any one of the four is an excellent choice. There are two differences which make up the four variations. First, there is an f/4 version and an f/2.8 version. Add to that the IS version of each, and the total is four.

First, it is important to know that each 70-200mm L lens version has excellent build quality and superior glass. The "L" in the name actually means Luxury. It is the highest quality of glass and building materials, making it much more expensive than non-L glass. There is low-dispersion and ultra-low dispersion glass in each of the four types. This basically means that the glass used (dispersion glass) is not subject to the same deterioration of quality as non-dispersion glass. It will not distort the images, making the image quality much better.

Another plus for the Canon 70-200mm lenses is the non-rotating front elements. This feature is important for maintaining focal quality, but it is also important if you are using certain filters, such as circular polarizers.

With the high range of focal length, having either f/4 or f/2.8 allows you, the photographer to have relatively low light photos without the danger of poor quality that comes with higher apertures. Obviously, the f/2.8 will allow faster shutter speeds than the f/4, making it a better choice if you are doing indoor sports where you will need the fastest possible setup.

Each of these models is also equipped with an ultrasonic motor, making the focus time almost instant. There is no searching as with other lesser quality products. The non-rotating barrel is also an asset when it is focusing. Auto focus is also present in conjunction with the ultrasonic motor.

The differences among the four Canon 70-200mm lenses are in the aperture (f/4 or f/2.8) and the inclusion or exclusion of IS (image stabilization).

Starting with a non-IS f/4, you get two advantages. First you will pay the least of the four, in fact, you will pay quite a bit less - about one-third the price of the most expensive one. The second advantage is the weight. Because there is less glass, the f/4 is much smaller and lighter than the f/2.8.This factor alone has been the deciding one for many photographers. The extra weight of an f/2.8 lens can cause fatigue much quicker.

As you add IS and wider aperture range, you increase the price and the weight with each addition. But as mentioned earlier, any one of these Canon 70-200mm Lenses will make a welcome addition to your camera bag. Due to the zoom range, there is so much versatility. You can shoot portraits, modified landscapes (not enough wide angle to use for dedicated landscape photography), sports, nature, and almost anything you can think to shoot.
