Canon 1.4 teleconverter

[LesWurse]

 Will Canon's 1.4 teleconverter be compatible with an EFS 55/250 zoom lens on my 60D?

[jrhoffman75]

No it's not.

[LesWurse]

Thanks - that saves me $350!

[PajamaGuy]

...where did you find it for $350?

[LesWurse]

Used with a E+ rating at Adorama.com

[PajamaGuy]

...guess I don't know what an E+ rating is - for me Adorama shows $429...

[LesWurse]

The $349 price was under "used lenses".  E+ rating in "Adoramaese" means better than average for a used item.  There was a used Canon 2.0 teleconverter listed also but I've been warned off of them.

In any event, my EFS 55-250 lens won't accept any teleconverters so I have no inexpensive way to reach the 400MM I'm looking for.

I believe Kenko makes an EF-S compatible teleconverter. But, if you decide to purchase be sure to get it with return privileges since you may not be satisfied with picture quality.

[LesWurse]

Thank you. I'm not familiar with Kenko so I'll do some research.

"... I have no inexpensive way to reach the 400MM I'm looking for."

Well that isn't exactly true!  

There is a 400mm, 500mm and 600mm fully manual lens made that is sold under several brand names.  They all sell for less than $150 bucks.  Much less on the used market.  I have seen them used for $35. Are they great lenses?  Well I suppose you know that answer but they are serviceable. I had, probably still do have, most of them from back in the film days.  I don't think they have changed a bit since then.

Big question do they work?  Yes, they work.  They do make a usable picture if you don't get too critical about it.  They are fully manual.  They are pre-set but you focus with it wide open.  They are all T-mount and it usually comes with the lens so mounting to your camera is no problem.  If you should go used make sure it is the right T-mount.
