Currently I've been running an EOS M100 with the stock 15-45 mm, f3.5-6.3 lens. I've recently acquired a sigma 17-50, f2.8 lens and adapter to fit the lens to the mirrorless M100.
How worthwhile would you folks view it pick up a new body. How much would I be looking to spend to find comparable to better image quality, better low-light photos, and quicker focusing (or is that going to be a primary function of the lens). I recognize the lens is not an ideal low light lens also.
My focus right now is currently live music events so my thinking was this would serve those purposes.
Please share your thoughts, I know very little about photography on a professional level but I'm passionate and pursuing it aggressively. Thanks for your input, I really appreciate it.
