Question about Digital Rebel - lens versus moving subjects

by Acts7 / November 30, 2004 4:47 AM PST

Im new to digital / photohraphy in general.

Im kinda confused because Ive used the point and click so long I can take pictures in my sleep.

Okay so if my 3 year old is at soccer practice and I want to capture him and his buddies...
Is the f stop what Im concerned with and do I want that to be high or low?

My other concerns are night photography and portraits.

What lens would you reccommend for each. Why are you reccommending those? For which would I want a small fstop and which would I want a larger fstop.

At night do I then want to let in more or less light? IF Im capturing streetlights etc... And if less or more how does that relate to fstops?

Thanks a TON

Wow....3 year olds playing soccer....that should be a sight. Absolutely the time for a photo.

The digital Rebel would be a good choice. I would get the kit version that has a zoom lens with it. Then you need to buy a fast lens. But fast zoom lenses are EXPENSIVE. Buy the standard (non zoom) EF 50mm f1.8 lens. You can probably find that for about $100.

When used with the Rebel, it will perform the same as a 80mm lens. Due to the difference between the size of the sensor as compared to the size of a 35mm negative.

An 80mm lens if perfect for portraits and should serve well on the soccer field. The f1.8 setting is good for the those night shots and it is helpful with portraits because it can produce a short depth of field. That way you can cause the background to be out of focus and less of a distraction.

The confusion with f-stops: A large opening (to let in more light) is a small number (f1.8). A small opening to reduce the amount of light is a large number (f16).

You can also increase the amount of light going to the cameras sensors by changing the ISO setting in the camera. With film cameras you bought a faster film. With digital cameras you raise the ISO setting. The Rebel has quite a few ISO settings.

So then you are reccommending a lens like this?

Two questions - since its not a zoom lens will it still autofocus? To my knowledge this item is not on display anywhere that I can check it out so forgive my iignorance.

What I mean is when I half-depress the "capture" button will it focus or is is more what you see is what you get?

Finally do you know anywhere that I can learn more about the different canon lens - I dont quite understand how to find a good zoom lens that will take great pictures. There are some reasonably priced ones like - 150 but those are obviously the cheaper ones as the almost same model number can also be found on the same sites for 500+ dollars.

Thanks

Yes, the lens in the Abes ad is the one.

This is the standard lens that comes with most Canon SLR cameras if you buy a camera with a basic lens. The camera stores do not push this lens because it is so inexpensive.

The EF in the lens name indicates Electronic Focus.

At this point you need to visit a camera store.
Not a Circuit City type store, but a camera store.
You don't have to buy anything, you are just looking.
They will have the various lenses and know for sure what works with what. Plus you can get your hands on the camera, which you want to do before you buy.

Here is a link to Canon SLR cameras and lenses

http://consumer.usa.canon.com/ir/controller?act=ProductCatIndexAct&fcategoryid=111

Zoom len prices run the gamut, from just over $100 to over $10,000. Have you seen those large lenses the photographers use on the sidelines of football games.
They are way bigger than the camera they are attached to, and very expensive. Generally, the longer the zoom and the lower the f-stop number - the bigger the price.

I'm not sure whether my reply can be any help to you. But,I'd like to give some personal comment. Actually, Canon produced many types of lenses. Visit the Canon's website and you'll find what they are. It depends on what kind of picture you are taking. For example, Macro lense will be good when you are capturing an object in a very close distance, such as insects and flowers. Supertelephoto ( big zoom lense ) will be good for taking picture from a very far away distance, like animal in a safari or soccer field. But, mostly the appropriate focal length lense is around 20-150 mm. The smaller the focal length, the wider the landscapes. For Canon, L-series lense are very good , considering the contrast and aperture. But, they are very expensive, mostly the lense cost over $ 1000. Any way, the lense will not be very helpful when you did not set the right picture techniques, for instance, right aperture, right shutter speed, dimmer lighting, and incorrect ISO setting.

For what lense to buy, it's hard to tell you exactly. You may read some of the previous comments here about lense for Canon Digital Rebel. Most of replies were very good. For most digital SLR camera, you must not disregard the cropping effect ( multiplier ). You need an extra wider lense ( such as Canon EFS )if you need to take the wide landscaping. But, for zoom, it will be the add-on. Good luck.

Thanks for the advice. Digital retouching and cropping effect is one thing I consider myself an expert at.

Im very concerned about capturing sharp clear images. Ill search the forums for any reccommended books. In the meantime - if you can reccommend any that would be great.

Thanks again.

ps I took your advice snapshot2 and ordered the Canon EF 50mm F1.8 II SLR Lens -52mm- USA
I can t wait to try it! thanks for the advice!

I checked a Digital Rebel (drebel) forum and found a thread on the 50mm lens.

http://forums.dpreview.com/forums/read.asp?forum=1031&message=11280978

It starts with someone wondering about soft pictures with that lens.

What some people see as soft is actually a narrow DOF (depth of field) when shooting at f1.8

That is what makes it desirable for photographs of people. Read all the links in the thread because many have sample photographs that clearly show depth of field and how to use it to your advantage.

There are a number of photos taken at high ISO settings (800-1600) which are good examples of the low noise level of the Rebel.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
