Part 2 What digital cameras 4u?

What Aperture Lens:

The smaller the number the better, it is always marked with "f", for instance aperture range: f2.8 - f4, if it is constant on the entire zoom range, let's say f2.8 on all zoon range - excellent, the longer the zoom range the harder it is to produce a small aperture number, for instance a zoom range of 36mm - 420mm (12 X) if it is f2.8 on all the range it is impressive. a camera with Aperture range of f2 - f3 Very good. Higher aperture than f5 will produce less desirable results.

Zoom Range:(Optical)

The longer the range the better, you can catch a distant object, make nice close ups and portraits, it gives you more accessibility, flexibility and creative options. A long 420 mm (12 X) is excellent range BUT, you need to understand that the longer the zoom range the bigger the amplification of any hand shaking with the camera, therefore it is recommended to hold your breath, be as stable as you can with your hands and body but even better yet to use a Tripod. I would even compromise a bit on the range to be 370 mm (10 X) " only ". Important feature on a long-range zoom is an Anti-Shake or Image stabilizer. These features compensate approximately one f stop or more on movements.

I referred here to Optical zoom, there is a digital zoom in addition but usually the quality of it is very low, some salesmen tend to confuse the customers by multiplying the optical zoom by the digital zoon and claiming the camera to be 12 optical x 4 digital = (48 X)! Ignore such statements, refer just to Optical zoom.

In the old Film cameras a long zoom range meant a very long bulge, in the current modern Digital Cameras it extends less than an inch and stops, all the rest is done internally by the Cameras optics.

Wide Angel:

Most Digital Cameras do not have wide angel! It is one of the their biggest shortcomings, 36 mm or even worse 37 mm is not a wide angel zoom, as a result when taking pictures indoor you will notice you cannot catch a better part of the scene or only part of the room, when shooting outdoor you will notice that only part of the landscape can be included in the frame. Not to worry, there is a solution! Wide Angel Adaptor, it is an add on which is placed over the existing lens. It can be (X 0.75) = 28 mm, it can be (X 0.66) = 24 mm which is excellent. There is an additional charge for adopters as they are produced either by a third party or the original manufacturer of the camera. Adaptors give small Distortions so as a rule of thumb it is much better to have the original manufacturer adaptor as it matches optically much better. There are even Macro ad on Adaptors available.

LCD Screen:

The bigger the better, average size is 1.8", but there are models with 2" and even 2.5", another feature is a swivel (flip-out & twist) LCD screens, you can show your kid His picture in real time, and it can help you take a difficult angel and access shots. The LCD screens have one big problem, that is, under sun light and outdoor conditions it is very difficult to see the picture on them. Therefore, if it has Anti Glare feature it's better. The more pixels the better.

ISO Rating:

This one is important to actually check in the store and observe the results carefully. The wider the range the better, both on the low and high sides of the scale. If it is less than 100 it means you will get very good results in bright day light sunny conditions ( Iso 50 or 80 ), if it is Iso 400 and up it means you will get excellent results on low light conditions. Some of Digital Cameras don't perform well in Iso rating of above 200, (e.g. you will see a lot of noise and snow flakes), this is why I recommended verifying it.

Optics:

The quality of the Glass Optics is Important, some of the Manufacturers wave with their Optics Brands well known producers like:

Leica lens
Carl Zeiss lens
Schneider-Kreuznach Variogon lens
Nikkor Lens
Canon Lens
Etc’.
Additional points:

Auto Focus - The more points the better - (9 Points is very good).
External Flash option via hot shoe a plus.
Lens Protective Hood - Better Light input + physical protection of the lens.
Who is the Camera manufacturer?

Most of the Digital cameras are designed in Japan, it is very important to choose a reliable producer with strong and experienced knowledge of Cameras, with a large variety of models and commitment to service and excellence. Always think who is the manufacturer, is he coming from the film field, Printers producer, electronics or has he dealt with cameras from day one.

Summary:

The economy of the Digital Camera is not cheaper than Film Cameras.
The overall result of using Digital Camera is improvement in our recorded memories, we shoot much more, correct and delete bad ones and Store only the very best.
Examine and test the Camera at a real store only then compare prices in the Internet, buy only at reputable store.
Decide on a Budget and stick to it, Take into account all the accessories such as bigger memory card of at least 256 MB.
Aperture lens - The smaller the "f" number the better, Range between f2 - f3 is very good, f2.8 across all the zoom range is excellent. Especially if the zoom is long.
Zoom range of (12 X) or (10 X), with Anti Shake or Image Stabilizer is great, Consider adding a Tripod.
Wide angel adaptor is most important (0.75 X) or even better yet (0.66 X), original manufacturer adapters will give you best optical compatibility.
LCD Screen - The bigger the better, Flip out & twist, Anti Glare, High Resolution.
ISO Rating - Preferable range 50 - 800, settle for 80 - 400, Test It!
Optics - well known manufacturers will give you better quality output.
Auto Focus - The more points the better - (9 Points is very good).
External Flash option via hot shoe a big plus.
Lens Protective Hood - Better Light input + physical protection of the lens.
