I have an opportunity to upgrade my existing Tamron 70-200mm f/2.8 Di VC USD (call it the G1 version) to either a Sigma 135mm f/1.8 DG HSM Art series tele... OR a copy of the new, G2 version of my current Tamron 70-200mm f/2.8 zoom.
On one hand I'm drawn to the Sigma because I really do love a good prime and the Art series primes just blow me away. The 135mm focal length is just awesome on a full frame body and would be just the ticket for portraits. Unfortunately I'm a little afraid of the flexibility of the big Tamron I'd have to give up for Sigma. The image quality on on this new Art lens is also staggeringly good. Jaw droppingly good and that's the Big Point in it's favor. Good as the IQ is on the G2, I don't think, can really compare to this lens. That's a huge factor for me in this.
On the other hand a fast 70-200 has been my "go to" lens for so long I'm not sure what I'd do without one. If I could only have one lens it might very well be a 70-200mm f/2.8 or something very similar. Tamron's G1 version of this lens is impressive, DxO rates it at as one of the top three "fast" zooms for the D750, but the new G2 version stomps all over the G1 in every category that matters according to pretty much every article I've read on the topic. What I feel I'd probably have to give up in the IQ department is made up for in my mind by the overall flexibility of the wider range of focal length and General Awesomeness of a fast 70-200.
Normally I have zero issue coming a decision on matters like this but not this time! I am about exhausted from chasing my tail on this one and I don't have all the time in the world to make up my mind. So, all that being said I'd like to hear your thought's. I'm hoping someone will say something that will trigger an "Ah ha!" moment and I'll know for certain which way to go.
And just so we're clear, "Why not both?!" (sadly) is not an option. The options are: 1. Keep my current G1 Tamron 70-200mm; 2. Upgrade to the Tamron 70-200mm G2 (in lieu of the G1) or 3. Upgrade to the Sigma 135mm DG HSM Art (also in lieu of the Tamron 70-200mm).
Thanks in advance for any considered input.
