Need some expert advice.
I have a DA 50-200mm that I use with my K200D for shooting wildlife and sports and have been very happy with it. I'm now considering upgrading to the 300mm level and the available lenses are FAJ 75-300mm and DA 55-300mm.
But since these two lenses also covers the same range as the DA 50-200mm and I'm on a budget I'm also considering getting a teleconverter instead.
For anyone who had had experience using a teleconverter with the DA 50-200mm, can you please share the issues and challenges you encountered? What brands work better?
Thanks very much.

Well I dont actually have a tele conveter ....
...but I would think that AF with the 50-200 and a teleconveter would be troublesome in anything less than bright conditions.
Also it limits you to f8 - f11 maximum at the longer end which may not give you an acceptable shutter speed.
The 55-300 is excellent by the way apparently much better IQ than the 55-200 and quite sharp all the way out to 300 (in comparison to its competitors). It is f5.8 max apeture at 300m.
55-300 costs around 350 US new ( or about 300 used in the marketplace here). What does a decent teleconverter cost?
In term of image quality it seems better to "center crop" from a wider shot than use a teleconverter to be zoomed in futher with the light loss experienced. (at least with lenses like the 50-200, 55-300, 75-300 etc). There are a few threads which discuss this question, and this seems to be the consensus.
If you are serious about sports action or wildlife then you probably would have to save up for a 70-200 f2.8, or a 300 prime. Both work with TC. Alternatively there is some older long Pentcax glass but the rarity keeps the price up unfortunately.
I am not so serious so only have the 55-300. I dont know about shooting wildlife but it works a treat at the zoo where the "wildlife" is not so wild.
