Who's the audience for the R7 ?
Birders ?
Anyone else ?
For me it'd be for aircraft. Airshows and planespotting. Wildlife would be a secondary use - I haven't done very much yet (just urban wildlife here in the desert), but I'd like to do more.
I'm very interested in the R7 II, but I hate that Canon has a huge gap between the RF 100-400mm f5.6-8 and the 100-500mm f4.5-7.1. The perfect lens for me would be the Tamron 50-400mm - good compromise between size/weight and reach, 1:2 half macro, weather sealed, function button can be set as focus limiter, etc. The wider wide end is also great for when planes fly in formation. Living in the desert, I don't like that the RF 100-400mm isn't weather/dust sealed. It's also a bit slow - very slow compared to the Sony 100-400mm GM (but of course it's way cheaper). The 100-500mm would be ideal of course, but there's the issue of price. I'm not adverse to paying for the better lens, but if the Tamron 50-400mm was available, it'd be perfect for me. I'd even pay a premium over the Sony/Nikon price if Canon wants their "taste". But alas...
I'm currently a Sony user, with an a6700 and the 70-350mm G lens. Great combo, love the low weight and size, but I think the side mounted viewfinder is making it harder for me to initially aim and track. Plus I wouldn't mind more FPS. I'd kinda prefer to stick to Sony (don't lynch me!), but Sony doesn't make a camera comparable to the R7 or R7 II (not yet, anyway). The ideal Sony combo would be the A1 II and the 100-400mm GM (and maybe the 1.4x TC), but the price of that combo makes any Canon camera plus the 100-500mm look dirt cheap despite the price of the lens. Yeah, there's the older A1, or the A9 II, but I feel like if I'm going that far, I might as well go all in. However, I'm not "locked in" to Sony - currently I only have the 70-350mm and the Sigma 10-18mm, and I can get that Sigma for the R7 if I feel like selling my Sony gear (although honestly I'd probably just keep it).
Still, I kinda like the idea of "growing" into the Canon ecosystem. With the 100-500mm lens I could eventually also get a full frame body like the R5 II, which is significantly cheaper than the A1 II (I think the R5 II is a lesser camera, but still extremely good and more than "sufficient").
Obviously I'll have to wait for the R7 II to be released and for the dozens of reviews to be posted before I make any decision. Plus I'm still far away from affording anything - I've got a sizeable chunk saved already, but I'll still need a sizable chunk more.
Anyway, thanks if you've actually read through all my musing and ramblings. I'd be grateful to anyone of they have any thoughts to offer.
