The Teleconverter Dilema

I need a new camera lens. The problem is, I can't afford a 50-500 which is what I really want right now. Would I be better off going with a 2x teleconverter for my 75-300 for the time being? And if so, what is it going to boost my viewing power up to? I am just worried about losing quality through the converter.

If you use Canon you can't even use the converters on the consumer lenses (probably the same with Nikon). But I wouldn't use any converter on a consumer lens. Quality will not be good.

Be patient and save up for the 50-500

75-300mm x 2 = 150-600mm.

If the lens is f/4-5.6, it'll turn out to be f/8-11, and that's not enough aperture to get auto focus.

The viewfinder will be VERY dark.

The quality will suck, if the lens is not very good, it'll be horrible with the extender.

I'd really try to save for the 50-500 rather than extending the 75-300.

EDIT: Tim beat me by 27 seconds!

Ditto on all points! Save your pennies.

I think you're right Tim, it's similar with Nikon. The TC xx II series will generally work with the longer AF-S lenses, but not with older or consumer level lenses. The 1.4x and 1.7x TC's get pretty good reviews, but the 2x has had some poor reviews. After doing lots of research I went with the 1.7x and it's performed pretty well.

Yup, i dont even like using a 2x on my 70-200LIS or 100-400LIS let alone a 75-300 consumer lens.

Save for the bigma.

Do you think the 100-400L of canon is better than the 50-500mm?
I see this lens higher in quality!!

The two examples of 100-400L I've tried were a lot sharper than the 50-500 I tried. I think it's very easy to see that a 4x zoom L-lens from Canon makes higher quality photos than a 10x zoom EX-lens from Sigma... Just the look of it... IMO

Alternatively, consider the 170 - 500. It's cheaper and I'm very happy with mine but, like the "Bigma", it really needs good light.
