Hello all! New member here, so go easy on me I've been an amateur hobbyist photographer for years and in the past couple years I've started to get more serious by doing small client gigs (family portraits, babies, engagements, etc.). I used to shoot with a Nikon D5000 with a 35mm f1.8 that never came off my camera, but I recently made the switch to FF with a combo of a Nikon D610 and 50mm f1.8. As you can tell, I love shooting with primes. However, as I start to take on more work, I'm finding them to be limiting and I could really use some more versatility in my life. So, on a whim, I purchased a Nikon 24-120 f/4 lens. Now of course I'm having a bit of "buyers remorse" and wondering if I made the right decision. I took the lens out on a shoot and was actually very impressed with the quality and versatility of the lens. It was way sharper than I expected and although it has some vignette/distortion issues, I still came away with photos I was very pleased with. However, my favorite photo of the day still came from my 50mm f1.8. So I dove back into researching lenses and found great reviews for the Tamron 24-70 f2.8 for almost the exact same price as I paid for my 24-120. Long story short, I'm considering switching out my Nikon 24-120 f/4 for a Tamron 24-70 f/2.8. My biggest concern is the slower focus of the Tamron for candid portraits as well as the fact that I've never purchased a 3rd party lens, as I've found Nikon glass to always be beautifully made with very few flaws. The 24-120 is no exception, this is no doubt a great lens. But as someone who takes a lot of portraits and is always on the hunt for more DOF, I really like the idea of f/2.8 vs. f/4. Does anyone have any thoughts on why I should stay put or why I should switch and go for the Tamron? Or should I be looking at something else altogether? Side note, the Nikon 24-70 f/2.8 is wayyy out of my price point at this point in time, otherwise I'd obviously be looking at that. Thanks in advance for any advice!
