Tamron 70-200mm 2.8 Lens question
After many good reviews on the above lens on this forum, I am going to order 1 in the next few days. I own a A350. I am a newbie to dslr cameras.
My question is what teleconverter would be my best choice to go along with this lens?
My main subjects will be in the nature field, moose, deer, birds that will be mostly from 75 to maybe tops 150 yards. I am looking to take photos that I can get some large enlargments to frame,, maybe somewhere near 16 x 20 to 22x28 with very good IQ. I need some advice on some of the best values on teleconverters.
Making the real choice ...
I guess I could probably weigh in on this discussion ... having that longer lens and speaking from serious experience across two different manufacturers of all these lenses and cameras.
- As far as my experience tells me ... it is unwise to use a T/C with the 70-200 /2.8 This lens is a top notch performer, but if you add a 2x T/C to it ... you have reduced the base aperture to f/5.6! With a circular polarizer on the front of it, it may not even autofocus properly.
- The TAMRON SP AF 200-500 f/5-6.3 Di LD has superior focus and IQ all the way through its range. It is designed to shoot long and weighes only 43 ounces. It is the lens to use, if you plan on outdoor "close-ups"
- T/Cs tend to degrade overall focus speed by nearly doubling it. The knock on the TAMRON 70-200 f/2.8 is its focus speed, although it is not as bad on the SONY mount as it is on the Canon ... still ... now, you are going to drive it even SLOWER? This is not a great idea.
- T/Cs tend to degrade Image Quality (IQ) ... so if you have a great lens, then add a coke bottle bottom to it ... what's the point? By owning a 70-200 f/2.8 lens, you are already stating you actually care about your imaging. Buy the longer glass ... to add it to your selection ... not some kind of emergency optical band-aid!
Finally, others have been in your position and if someone is advising you that a T/C is a good choice ... well, let's see the evidence on a routine basis, shooting long.
I got this with the TAMRON 200-500 ... and I am not complaining.
