This lens looks sharper than my non-IS version. Is that commonly observed?
I'm looking to upgrade; shoot mostly people, and a lot in church where flash is not allowed. I have a 5D3, and have a Tamron 24-70 2.8 VC which I use some. I don't have a great fast light lens for longer work..... just my 70-200 f4, 85mm 1.8, and my 135L. I'm looking at parting with some or all of these lens to gain some speed and IQ. With some cash, I figure I have $2000 to work with. Among several thoughts:
A. Just find a used 70-200 2.8 ii and keep my old 85 1.8, and be done.
B. Find a used Tamron 70-200 2.8 VC, and buy a new Sigma 85 ART
C. Find a used 70-200 f4 IS, and buy a new Sigma 85 ART
I don't need the 2.8 bokeh as much as I need the extra stop of light in my low light church where I do a ton of first communion, baptisms, confirmation photos. I love the photos in here but very few are utilizing IS. Shooting in a church, where you have to get it right, if I'm at 150 mm, can you produce crisp sharp images at 1/60? 1/90?
Thank you in advance for thoughts you may have.
