I'm up over 1300 images so far with the R7 now. Yesterday was an 830km day with many stops for photography. I went up north-east of Barry's Bay towards Algonquin for the first time, and revisited some places I'd seen last year south of Killaloe and north of Highway 7.
I did some RAW Bursts of Dragonflies and some regular 15fps bursts of Redwing Blackbirds. Two takeaways are that an EF 75-300 II USM is not a viable lens for this due to both IQ and slow focus and my AF settings are not very optimal. I'm not exactly experienced as a bird photographer, but it was fun.
I also shot a lot of bracketing bursts, 3 shot/1 stop bursts which is my standard for any landscape shooting. That worked very well and having track & recompose back was really nice. The R7 does that on par with the A7RIV, the OM-1's AF didn't do that well at all (AF-C+TR would lose the track point very quickly). This is a method I started using the the A7RIV and have come to love, it's like focus & recompose, but with the subject staying locked. One nice thing with the R7 is it will subject detect automatically while using this so, as long as I get a bird/bug near the point, it will lock on and I can start tracking it.
Overall I'm getting comfortable quickly with the R7. I've added the 10-18 STM and a TTArtisan 25/2 to the collection (and borrowed my partner's 75-300 yesterday). That gives me 16-240mm-e setup (vs the 24-300mm-e I had with the OM-1), but since the pixel density is similar between the R7 and OM-1, I can crop down to m43 to get 300mm-e. I'm really losing aperture and IQ with the 18-150 vs the 40-150/4 Pro, but gaining better close focus.
I do like having a proper UWA zoom back, I've been using primes for that role since I sold the m.Zuiko 9-18 a few years back (excepting some brief use of the ZA 16-35/4 in fall 2021), and having a zoom for that is a nice change. With the OM-1 I did't have any wider than 24mm-e options, but I didn't really miss it either, the subjects I shot with the OM-1 didn't really benefit much from wider, although I would have missed a wider option for sure if I'd been carrying the OM-1 yesterday.
I am planning on adding a telephoto next (likely the RF100-400) and then a higher-end normal zoom to replace the good but not quite excellent 18-150 as my go-to midrange zoom. Good chance that will be a Sigma 17-50/2.8 in EF mount if Canon doesn't bring something to the table soon or allow Sigma/Tamron to make 3rd party RF lenses. After that a native Macro is on the table, but I suspect I'll stick to the cheap manual focus primes for anything else short term.
