I have five of these Sandisk Extreme III 2GB CF cards. They are very fast and have mostly been reliable (hence the three-star review). However, there is more to this product than merely the item itself. The other question is how efficiently the manufacturer handles things in the event of failure. I recently had one of these cards fail and I have been disappointed by Sandisk's warranty service. The situation was very straightforward. The card failed. I lost only one photo. No data needed to be recovered. I had all the information available, including a copy of my receipt to prove that I am the original owner. After two weeks, I am still sending follow-up messages to Sandisk asking them for a return authorization, and getting no response. Sandisk has not actually declined to replace the card -- but their process, which was already rather slow, has led to a dead-end. Several years ago, I had a Lexar CF card fail. It was a quite different experience. They replaced the card promptly. I recognize that all electronics products can fail -- but the real test is how well the manufacturer responds when that happens. My next CF card will be a Lexar, not a Sandisk.
Customer Review: Great Card
While I have had many compact flash cards of varying sizes this card for the size and price was a much better bargain then those of the others. A lot of storage with a little price. Never had an fault or error and don't think I ever will.
If you care to examine and look carefully at some of the photos on buildings, you may realize that they tend to slant backward or have the falling over effects. You might think that this is purposefully created, or you are not bothered by it at all. Well, in fact, this is a common problem when taking pictures on buildings. This effect is termed as converging verticals. That is, the verticals lines will converge if you project them to the top. You can see an example of this effect here.
How does this happen? Usually, when you are faced with a tall building, in order to capture the full height, the natural tendency is to tilt your camera upwards to capture the top of the building. And in particular, this effect is common when you are using a wide angle lens. That is, the top of the building looks small while the base of the building looks big.
However, this distortion may not be a bad thing if you use it correctly. What you can do is, to exaggerate the effect by having more distortion. You can do this by going close to the building and point the camera upwards. But on the other hand, if you have only a slight distortion, it may give you worse effect.
Let us come back to the point to have straight standing building shot. The first step is to move away from the building and followed by having your camera straight. However, this option may not be away possible as there is a limit to the distant you can move backward. Nevertheless, try using this technique first.
Secondly, you can use a software called Elements 5 to correct this. However, this can only correct slight distortion. If your photo has verticals that are distorted too much, the software cannot do much.
The third option is to use a special shift lens. But this is an expensive option. This specialized lens uses a mechanism to shift the position of the lens independent of the camera. This allows you to keep the camera vertical but still include much more of the top of the building.
Above are three suggested techniques you can use when taking building photography to keep them straight. Explore them and see the effect yourself.
