I have problem to shot indoor portraits in low lights condition and restaurants . Most of time my 24-105 is mounted on my camera and F/4 is fastest I can get on it. I think if I had 24-70mm F/2.8 was my photo much better. i have used my 50mm as well but most of time put me in corner to get all in photo.I’m not sure but I need your help on this. Most if time my shot has noise .
I'm curious, what ISO were you at to see a lot of noise? Was it an unbearable level of noise? I use my 5DIII at up to 6400 ISO all the time and don't really notice much noise, especially after some processing in lightroom. If you were at 3200 or 6400 and did not like the noise, I'm not sure getting one stop of light with f2.8 will solve your problem. Even at f2.8, you're still going to need to have the ISO up there, depending on how dark the room is. You might just have to go with a faster 24 or 35mm prime.
As for the lenses, even though I have the Canon, I think both lenses are great. The Canon is just a solid lens that you know will give you the best AF possible and great image quality. The Tamron is also a very good lens by most accounts. Most people probably won't be able to see any drop off in picture quality compared to the Canon, and the VC is a great bonus. I think the negative comments it gets are generally over-blown and there are plenty of happy owners of the Tamron.
