Honestly, Ive used both over the years and the G2 is the way to go for an actual shoot. Variable aperture lenses like the Tamron 28-200mm f/2.8-5.6 Di III RXD are great for hiking, but youll struggle once the sun goes down or you head indoors because it drops to f/5.6 pretty fast. The Tamron 28-75mm f/2.8 Di III VXD G2 is a beast on the Sony A7 IV for a few technical reasons:

• Constant f/2.8 aperture means your exposure doesnt jump around when you zoom
• The VXD motor is way stickier for eye-autofocus during movement
• Much better corner-to-corner sharpness for that 33MP sensor Looking for the absolute ultimate in versatility? Check out the Tamron 35-150mm f/2-2.8 Di III VXD. Its more expensive and heavier, but it basically replaces three primes. If thats too much for your budget right now, just grab the G2. You wont regret it for a professional gig.

Get the Tamron 28-75mm f/2.8 Di III VXD G2 because the f/2.8 is way faster for low light. The 28-200 is a decent option for travel, but the G2 works better for shoots.

Yo, jumping in a bit late here... honestly, before you pull the trigger, what are you actually shooting this weekend? Like is it a wedding, some sports, or just portraits? Knowing the gig really helps figure out if you need the extra reach or just better low light performance. Few things to watch out for tho:

• Dont buy gear right before a job if you can help it. You need a minute to make sure the lens doesnt have any weird issues or just to learn how the focus feels.
• If you want to save money, maybe think about renting? Its way cheaper than buying a lens you might only use once.
• Be careful with lenses that have changing apertures. They can really mess with your exposure if you zoom in while recording video or in manual mode. Let us know what you're shooting and maybe we can suggest some other cheaper routes like primes or something...
