I'm a hobby photographer. I like taking portraits, which I often do at festivals and conventions. I usually take the following gear: Fujifilm X-T2 (an APS-C sensor mirrorless camera), a 16-55mm f/2.8 (sometimes the 18-55 f/2.8-4 kit lens), a 35mm f/0.95, a 56mm f/2, a 90mm f/2 and a 135mm f/2.8. These are all small lenses that fit in my camera pouch easily. I mostly take head/shoulder portraits, with the 90mm lens, but the other lenses have their uses too. It depends a bit on how much space there is.
After publishing my latest convention's photos to Facebook and mentioning how much I love the 90mm lens, I received a message from a professional photographer. He told me I was stupid to take so many primes and I should use a single zoom lens instead.
I was looking at the Fujifilm Roadmap. If I want to go for a single zoom, I'd have to take the 18-135mm f/3.5-5.6. I could also get the 50-140mm f/2.8 and use it along with the 16-55mm f/2.8. He told me to get a full frame Canon body with this 24-70mm f/2.8 instead, since, he explained, it would be better than my current gear.
If I sell all my gear, I may be able to afford it. I love my gear, though, and I don't just want to sell it. It's light and small, good for videos too and I like the bokeh and I like the film simulation (classic chrome <3). I'm super sad about this.
Would switching to full frame Canon and getting that lens be an upgrade over my Fujifilm gear?
