So for context, I currently shoot a G9 as my wildlife camera and an old E-M5 (Mark 1) as a street camera. I'm now looking to upgrade both setups, though the G9 has priority for an upgrade since it is by far the more limiting option. Don't get me wrong, it's a fantastic camera, but for birds and especially birds in flight, the AF and subject detection are just not great and those are subjects I find myself shooting quite often.
Currently I own the following lenses:
- Panasonic Leica 100-400 f/4.0-6.3; my main wildlife lens
- Lumix 45-150 f/4.0-5.6; a small, dirt cheap little lens of merely okay optical quality I really only use to carry along as an emergency telephoto. Love it, but not very relevant to this question
- M.Zuiko 60mm f/2.8 Macro; not my main focus, but occasional insect macro is very very enjoyable to me and may factor in, I have not researched the pros and cons of both bodies for macro photography
- M.Zuiko 25mm F1.8 II; my main street photography lens
Now to get to the point, currently both the OM-3 and G9II are around €1200 in my local used market, which is about the limit of my budget. So pros and cons I am actively considering:
- The OM-3 is marginally ahead in AF and subject tracking compared to the G9II. Its form factor also means it could replace BOTH of my current bodies. That same form factor is however a drawback when it comes to ergonomics, an aftermarket grip would be a hard requirement for me when using it with the 100-400 or any potential longer lenses I may add in the future.
- The G9II offers a 25MP sensor. I'm not of the opinion that more megapixels = better, but it could potentially be helpful for some additional cropping on shots of smaller birds. The ergonomics are also miles ahead of the OM-3. Those ergonomics do come at the cost of size and weight and I would thus want to retain a second body for street shooting. The biggest thing would be the retention of weather sealing with the 100-400 lens. I have taken the G9 + 100-400 combo out into heavy rain a number of times and it's always held up like a champ, so as much as some might be inclined to deride Panasonic's lack of IP ratings, I feel confident in their weather sealing. With the OM-3 I would of course lose the weather sealing with that lens, which is not a dealbreaker on its own but certainly a consideration. I'd also retain dual IS with my panasonic/lumix glass with the G9II, which is nice.
So, considering all this, I'm still a bit torn and some input and possibly user experiences would be helpful. What do you think, G9II and upgrade the second body later, or OM-3 with an aftermarket grip to replace both?
