whats a good + resonably priced teleconverter??

Hey guys,

i just bought myself a pentax 50-200mm lens.. i was going to go with the tamron 50-300mm lens but it would have taken up to 3 weeks to get it here and also i can't use my filters on it... so i thoght id just keep my camera bag pentax friendly.. lol..

but now i was wondering what you guys consider to be a good yet reasonably priced teleconverter.... im thinking of getting one thats 2x so that i can get as far as i posibly can with this new lens... just incase i run into some wild life up in perrysound or collingwood when i go up in the summer/winter time..... i remember last year me and my friends saw some bears at the local dumps... i wish i had my setup then...

anyways if you guys could just shot some names at me and explain this whole crazy teleconverter world to me that would be great... the help is very much appreciated..

thanx

Personally, I'd stay away from a 2x TC. Remember you will loses 2 stops with a 2x TC. IQ will also suffer more than with a 1.4-1.5x TC. You need to balance reach with actual usability. That being said, The Kenko and Tamron TCs seem to do a pretty good job.

I've got a

brand new in-the-box Pentax TAKUMAR-A 2x TELE-CONVERTER that I have not used since my Tamron 1.4 arrived before it did. A cheap 2X, but you did say reasonably priced, right?

Complete with hard case, caps, and instructions. If this fits your needs, I can let you have it for what I paid - US$49.00, plus shipping ($5.00 within Canada).

Let me know- I'll probably be e-baying it.

No...

Basically I'm saying that the Tamron does such a good job for the bird photography I do and I can't afford (or don't want) to lose the extra aperture and the 1.4 with my recently acquired FA*300 gives me all the reach I need- for now.

With the 300mm lens and the 1.4, I get 420mm!

I had ordered the 2X to go with my 50-200, which would have me at 400mm max.

Go with the Tamron 1.4. I use it on my Tamron 28-300 with good results. Autofocus gets a little tricky, but it is good enough for some things.

I have a 2x TC that is aweful to use, but seems to work well with my manual lenses, so I keep it around for that.

I'd go with a K mount. Screw mount is for older lenses and you will need an extra adapter although I hear these adapters are cheap. I might be misinformed but you might also lose some functionality with the screw mount.

so does that mean that with a kaf mount or k mount the teleconverter goes on the body of the camera first and then the lens goes on to the lens... as where with a screw mount the lens goes on the body first and then the teleconverter??

you guys say to go with a kaf or k mount but does this perform better then a screw mount??

go w/ the kaf mount tele converter cuz thats what ur lenses are now...

screw mounts are old school, and you will need an adapter. (which will then convert it from screw to k mount)

kaf is same as k mount.....(af denotes autofocus)

teleconverters go in between the lens and the body regardless of mount type

Get the K mount. The screw mount is for the old Pentax M42 mount lenses.
