The converter is screwed in front of the primary lens and doubles the subject (shot). Does this added glass reduce the resolution too much? What are your thoughts on using these converters?

They're great when you need to take a picture of a bowl of porridge, and don't have a bowl of porridge.

Resolution is reduced and minimum focusing distance is increased. The expensive ones can be OK when used properly with a good lens. Using one that is oversize for your application helps - ie 58mm threaded on 52mm lens thread.

Thanks for your response - I understand you have past experience using these converters!

Yes.... In my example above, you would have to use a step up ring ( 52-58mm) . Also, you do not loose light with this type of converter. It is best to get a converter with filter threads up front so you can use a lens hood (important). If it does not have threads, sometimes you can glue an adapter ring in that will accept a hood.

The 2x converter I just received mounts on any lens with a 58mm thread therefore no adaptor is needed and it will take a 62mm front thread for filter mounting -- I don't know about a hood. I didn't spend much ($17.95 & free shipping) so I haven't tried this converter yet - it was made in China, shipped from California. So that is why I posted hopeing that someone had some experience with this sort of lens -- I guess I will have to try it on three of my lenses with a 58mm filter thread.

Don't expect much .......the "good' ones are $100 +

I have just tried it on my 28-105mm lens and am disappointed as the exposure is fuzzy (blurry) up close and 100m away. I do need to work with it for improvements and I do notice that at certain settings I do get some bokeh although not enough of it. I will try it on my100-300 mm lens tomorrow.

Your converter will accept a 62mm screw-in lens hood. These converters typically exhibit diminished image quality in the corners, which is why imagemeister recommended going at least one size larger (that better be why!. :lol: ). They are generally best employed on a 50mm (FX format) or 35mm (DX format) prime lens. They can be fun to play with, but don't expect too much in the way of image quality, especially with a zoom lens. Stopping down to f/11 or 16 may improve IQ (or not!). Since you have it, enjoy it!

I do have an EF prime nifty-fifty with a 52mm filter thread for my Canon T1i (APS-C) so I guess I would have to get a step up adapter (52-58mm) ring to have the converter mounted to my 50mm 1:1.8 II lens. Correct?? i.e. if there is such a ring!

That's right. Check ebay or stores like B&H in the US - they list these:

Get the cheaper ring, as it probably won't get a lot of use.

Well I just ordered the adapter ring for my 50mm 1.8 lens. I tryed out my 28-105mm lens and I played around with the f-stop till i got a decent exposure at 50mm. Can't wait to try out the converter on my 50mm lens

Thanks to imagemeister and Leitz for your help----What else do I need to know about teleside converters (2x)?? I know that they are not that great but I do hope to have some fun with them or why are they being manufactured? --- to double the function of a lens so that you don't need to buy one -- I guess that was what Lietz had in mind when he wrote me "They're great when you need to take a picture of a bowl of porridge, and don't have a bowl of porridge." HA HA!!
