Originally posted by pcarfan It sounds more and more like the sigma 100-300 will be my first and last tele, and i better get used to the max reach of 420 with a TC. I am not going to pay over 2.5k for a tele, and if I do, I want a substantial improvement. It looks like these two are mutually exclusive. Also, I've maxed out with the weight and size with the Sigma. The only way to go longer is to switch brands so I can get some professional grade 2X and even 1.4 X TC that are so readily available for Nikon and Canon. But, I am not going to give up my Pentax primes, so it is sigma 100-300 forever.......
@Oren, if you are considering the 300/2.8, and you mentioned Canon, I would look into Canikon's wonderful TC's that they make and the professional grade kenkos. Pentax has nothing like that.............
Sanjeevan, I really only made that comment out of frustration I think because for me trying to figure out two systems at this point wouldn't be prudent. I am taking a serious look at the Sigma 300/2.8 though as I do have the 70-200/2.8 covered unless a Pentax pops up in a couple months in the same price range. The reports of its preformance are very good from what I have seen.
I do love my 100-300 however and I purchased another Sigma 2x TC that I am going to give another go at today. I have about another good month of eagles on the Skagit and darn it!, I want some good shots from up there. Hopefully I will run into some Trumpeter Swans today also.
If Pentax announces what it is doing for supertele by that time I may hold out depending on what it is. ( fingers crossed )
As for the Canikon's TC's, it really is sad that Pentax hasn't came through yet. And I wish Kenko would at least release a pro-grade for us.
BTW, Merry Christmas all and may the new year bring joy and peace.
On another note: somebody can take me out and shoot me anytime now.
I purchase the Tamron DI macro that I will be testing today also.
It never ends.....
