just buy a longer lens!*

tele extenders are never designed for one specific lens and its optics!

the quality is poor, you lose a stop or more, no AF! no antishake (unless sony)*

it's what we sold in the 60's and 70's when people did not know what was good or bad!

*look for a good older lens with an adaptor to your dslr! plus you learn to focus!

Quote: With respect, that's a load of old nonsense. Extenders/teleconverters are just as popular now as they ever have been and are pretty much an essential tool for the serious wildlife photographer.

they might be as you say popular and we did sell alot of them but in the end a sad compromise,

BUT I like old nonsense, AND I was in the game for 20 years, and tried a LOT of useless 2x and 3x extenders, in real life the LOSS of light will hinder anyone doing wildlife, as you will have to add ISO or sloooow the shutter down you thenwill have to stop it down to gain sharpness, In general its a no

UNLESS THEY ARE MATCHED extenders are NOT good.

I enjoyed the really expensive laugh in the link, BUY second hand, an old made for film lens, you can pick them up really cheaply ie NOT MUCH MONEY (well not £8 grand! + lol )

depending on what you REALLY need, you can BUY an older piece of glass if you look around, then using an adaptor, if your A/S in in the lens tough, learn to shoot like the old'uns BUT A/S in the body sony (& think olympus?) no probs

I wasn't thinking of 20 year old 2 and 3X extenders, which, as you say, are best left alone.
I was referring to matched extenders, such as the Canon 1.4X extender. Admittedly, the slight loss of light can be problematic in some situations, but raising the iso isn't so much an issue these days as it once was, when having to push an already slow film was the only option. Shooting at iso 1600 and above when needed, is pretty much a non issue with the right camera these days.

The link wasn't actually posted for a laugh but to give an idea of the substantial cost involved in buying a longer lens, at least a lens designed for the job.

I don't know what older lenses you're referring to, but I would imagine they would still cost a good deal of money. Buying secondhand would be taking a gamble because if the lens in question is that old then the unavailability of parts could make it a very expensive paperweight, should anything go wrong. Personally I would rather save that money towards something better suited to the job, whether that takes a year or five years.
