Originally posted by vagabond79 I have really been going back and forth about which telephoto lens to get and feel like I just don't have enough information to make an informed decision. Your thoughts and experience would be greatly appreciated!
Teleconverter: Not opposed to it.
Fair enough a converter is a good option with quality glass
Originally posted by vagabond79 Lenses considered so far: Sigma 150-500 F5-6.3 APO DG OS HSM, Sigma 100-300 F4 EX, Sigma 120-400 F/4.5.-5.6 APO HSM DG OS.
No converter in existence will AF these lens properly besides the screw 100-300 (if you can find one)
Originally posted by vagabond79 Lenses I want to avoid: DA* 300mm (would like to get a lens capable of FF)
Lenses I have: Tamron 70-200mm F2.8
Qualities I want most in a lens: IQ, sharpness
Things that don't bother me too much: Weight
My concerns:
- Will a long prime be too long at times shooting air shows/aviation and sports? I feel like there are instances even with the 70-200mm that I zoom out because a subject comes too close.
- Will a prime telephoto lens coupled with a teleconverter still yield good images?
I think these are most of the things I'm trying to factor into my decision. Thank you in advance for your advice.
From your words your looking for reach , Ignoring your price points a quick look at options and market
Sigma 50-500 , Pentax da* 300 , Sigma 100-300 = pro level sports centric lens very High IQ
Sigma 150-500 F5-6.3 APO DG OS HSM, Sigma 120-400 F/4.5.-5.6 APO HSM DG OS = consumer long zooms IQ OK target use I don't know check for rear focusing and short throw
As to length for air shows/aviation traditionally your looking for 300mm+ But if your shooting is zooming out a 70-200 maybe you don't need a long lens?
IQ wise in order
1 da* 300
2 Sigma 50-500
3 da* 300 + 1.4 HD wr
4 Sigma 120-400
5 Sigma 150-500
