This is encouraging, @theoutdoorsman. You’re learning the pros/cons of your equipment to quickly make decisions on what “actually” is best for your needs. And even though the Z-30 was relatively new, you were willing to let go of it for something better. You’re off to a great start.
I wholeheartedly agree with having multiple lenses. I have 3 lenses that I use regularly, all f/2.8: ultrawide (16-35mm for most of my landscape work), standard (24-70mm for most portraiture), and telephoto (70-200mm for animals, using a 2x extender when needed). I’ve used this basic setup, with various different lenses, over the years and can never seem to find a better arrangement. I could try covering that same range with two (or even one) zoom lens, but I would be sacrificing f/2.8 aperture and general image quality. Yes, it’s a hassle to constantly be switching lenses (though having multiple bodies has helped with that) and it’s a LOT to tote around, but the quality and versatility has been totally worth it.
I hope that helps in your decision on what other lens(es) to get! What is the lens you currently have that you are thinking of keeping?
