teleconverter for digital rebel

[botak]

has anyone tried any teleconverter, other than canon brand, that works wonder with the dig rebel?

[ron chappel]

I've tried a couple of brands and seen a few comparisons online.The little that i can say is that there are no brilliant ones at bargain prices-as there are in lenses,but there certainly are better value ones
(such a upper mid range one beating a lower midrange one as i saw online)
I'll see what i can find...

The Sigma ones work great, they are also compatible with the Canon lenses that operate only with the Canon type teleconverter.

If you buy 3rd party, make sure your lens will work with it and that there is no risk of damage to the elements.

Rule of Thumb. With an L lens, use the Canon teleconverter. With an ordinary lens, use an ordinary (non-Canon) teleconverter.

I use a Tamron 1.4 TC with Canon 300L f4 and find the results very good - only about $80 in bandhphoto - about an third of the price of the canon TC.

The best way is slightly tedious but works well

In elements resize to the dimensions you want then go 'file' and 'save for web'.
This will give you two images-a before and after view

In the control settings on the right, choose 'jpeg high' then fool with the quality setting until it looks good enough while being a small enough file size

-The file size is shown at the bottom of the picture

Oops ,i should have mentioned-

Any and all resizing (up or down) will absolutally kill fine detail -there is nothing that can be done except make sure you use the 'resample' (highest quality) method for resizing.
Once you have resized then apply USM until it's sharp enough

I first ran into this problem when first started playing with my new 300D.I noticed that a night landscape shot (raining,lit by lightning) showed clear raindrops at about 5-10 meters.
ANY resizing immediately lost this fine detail .
We all have heard that upsizing is a bad thing but i really didn't expect that downsizing would have a similar effect!
I searched for an answer for this problem on all the inertnerd forums but it's simply unavoidable.

What I have found is to first change my resolution of the photo to 300dpi (what most photo labs use to print with) and then do my resizing. I have been very happy with the results. Try resizing a photo with out changing the resolution and than make a copy of the same pic, change resolution to 300dpi, resize and compare the two side by side. I think you will notice the results. Hope this helps.
