300D, Best Lens For Distance

Sat May 22, 2004 7:35 am

Hello,

A great thing happened today, and I have been offered a lens for my 300D, but I have to ask, which is best? I am looking for one that has good zoom, but nothing like a 400mm fixed, infact, no fixed lenses at all. So what should it be? I want nothing either, that will "just work in most places", I want all places.

Thanks

How much do you plan on spending? If cost isnt an issue go with the 100-400mm L IS.

Ryan, since cost is an issue, do what I did.

Go with the Canon 75-300mm USM. Cost me about $220 over at Mike's, and it works fine for me. The only thing is that between 200-300mm, I keep the aperture at no wider than 11, otherwise it gets soft.

But with that in mind, it's a good lens to go with IMO

Nope, cost is not an issue

Is 100-400 the equivilent of a 4x zoom? I want better than that

Here in Denver, the 100-400 will be all you will ever need. Remember the 300D has a crop ratio of 1.6, so do this: Multiply 400 by 1.6. That will be how much you get when in full zoom, for example: When I zoom to 300mm, It is actually 300x1.6, which equals something in the neighborhood of 485mm.

That is one of the many reasons why I like the 300D.

The 100-400 is Canon's longest zoom...so if you won't go for primes, forget it (at least from Canon). How about a 28-300 and a 400 DO?

OK, I suspect you're still thinking in digicam terms. If you really mean the best, you need to think in SLR terms.

All zooms are a compromise on optical quality, the greater the zoom range, the more you sacridice in quality. So what do you want? If zoom range is a big issue for you get the Sigma 50-500.

If image quality is the important, the Canon 100-400 is probably the best long zoom you can buy.

If the ultimate in image quality is what you want, then forget zooms altogether and look at the Canon 500mm or 600mm f4LIS - if price really isn't the issue that is, as either of these lenses is the price of a car  Smile

"Is 100-400 the equivilent of a 4x zoom? I want better than that"

No it isn't! To get an equivalent x zoom number you are looking at, you divide the total focal length (including crop factor) by 35 to get a conventional x times zoom number. In the case of the 100-400L it would be 400 x 1.6 = 640mm. Divide by 35, gives you 18.3x zoom - that's what it would be if it was on a normal digicam. Definitely not 4x!!!

I'm sure someone will correct me if that isn't right!

I believe zoom refers to the amount of difference between wide angle and maximum telephoto. It's a deceptive word -- if you had a lens that had 20x zoom but its wide angle was 12mm, you'd only be looking at a 240mm lens on the long end. On the other hand, a 100-400L has a 4x zoom, but is 400mm at the long end.

Zoom is versatility, but focal length (mm) is magnification. The more zoom, USUALLY the more tradeoffs (IE maximum aperature, image quality, distortion, abberation, WEIGHT, etc).

Money not an option? Get a 400 F2.8 and go from there. Sharp and fast, but expencive... or you could get a 500 F4. E-mail me your address and the hours you're at work, as well.

Thanks for the explanation Mike. I assumed United4everDEN was referring to digicam terminology when he said 4x zoom and "I want better than that", so my explanation was to give an equivalent digicam optical zoom figure based on the full focal length of the 100-400 for comparison.

It's known to be one of Canon's "weaker" (in terms of image quality) L lenses (still great though). It also lacks IS which is rough if you've become really used to it, but they new 28-300 does have IS but costs quite a bit.

Does the amount of zoom you use effect the image quality?

Depends. If you are using an Optical zoom lens, then it depends on the lens. If you are using Digital zoom, well, lets just say I feel sorry for you.

Well, the Sigma lenses are known to be good all around in the high mm ranges. I might suggest a 50-500 or a 170-500 depending on what gap you need to fill...

I believe the 170-500 is somewhere in the 500$ range and the 50-500 is in the 900$+ range.

You can pick up a 100-400 L IS locally for $1600 bucks. You can save about $200 bucks if you buy online.

and yes, a 100-400 is a 4X zoom.

Is the Canon 75-300mm a good zoom?

How many times zoom is the 28-90? What about the 28-135 and 35-350?

Would it be 3.2 and 4.8 and 10 respectively?

Thanks
