Hi all,

Apart from the EFS 18-55mm len with Canon 300D, I would like to equip one more affordable len in 300mm range. Any model below $500 can be suggested?

Thanks!

The 75-300mm IS lens is in that price range. You won't find a prime (non-zoom) in that range however.

Is there a EFS series of 300mm equivilent for 300D?

It seems like the EFS 18-55mm is cheaper than a regular 28-80 mm, so maybe the EFS 300m version is in the less than $500?

Just speculating.

Other non-Canon lens e.g. Tamron, Sigma 28-200, 28-300 is good or not?

Thanks!

For the 'cheap' Canon lenses, it's difficult to say things like 'Canon lenses are always better than Sigma or Tamron'. You should really look at it on a lens by lens basis.

The only generalization you can make here is:

The higher the zoom range of the lens (e.g. 300 divided by 28 means it's approximately a 10x zoom, vs. 300 divided by 75 is a 4x zoom) the more difficult it is optically to have sharp images on both extremes (fully zoomed out to 28, and fully zoomed in to 300).

So, if you have two lenses of the same glass and build quality and manufacturing standards, the 4x zoom lens (75-300) will yield sharper pictures fully zoomes oud and fully zoomed in than the 10x zoom lens (28-300). For this reason, 'Pro' photographers tend to prefer 4x zoom lenses over 10x zoom lenses (primes are best). Hobby users are just happy with the better ease of use.

On the other hand, that image you lose because you're just exchanging your 28-70 with your 70-300 lens might just have been your greatest shot ever... :)

Plus ...

your 18-55 gives you most of the range (28-55 out of the 28-70) you would use of the zoom range of the Tamron if you decide to buy the Canon.

The IS on the Canon lens is another definitive advantage (do forum search for 'IS').
