Thanks.Check as to whether these cameras can provide bird identification automatically. With Nikon this is true for only the Z8 and Z9 cameras. This feature helps not only to zero in on the eyes of the bird but also to focus on a bird when it is partly obscrured with branches as often is the situation.
Seemingly, I never hit submit on this post a couple of days ago ...
A couple of thoughts: "no particular reasoning" will not cut it, which type of birding: sitting in a hide with a stationary camera on a heavy tripod is a very different proposition to a person hiking around and taking photos primarily for id purposes using only handheld kit. Do you need a kit that can last through a shower or do you not care?
I personally think you need to consider m4/3 as a different approach to bird photos.

Thanks.Camera selection really depends on what your desired outcome is. Is it for bird ID, or for social media posts, or for large prints on the wall? Are you a pixel peeper? Some people get very competent pics with 4/3 but I found that I needed at least aps-C and eventually migrated to FF. The $$ and the burden (size/weight) goes up accordingly and you just need to define your expectations first.
I will say that one advantage of LOT of mp and large sensor is that even very distant shots, provide useable blow-ups for ID.
Other considerations are low-light high-iso performance, lenses available, and AF speed and success.
I'm happy in the Sony universe and used an a6600 for a long time, before moving to an a7RV. Their 100-400GM is a fabulous lens, barely long enough, tack sharp, and actually does pretty good almost-macro.
If you want to compare cameras and IQ, I find dpreview's camera reviews very useful. E.g. https://www.dpreview.com/reviews/sony-a6700-review#HC
Go down to Studio Scene and select the cameras you are evaluating.
The OM1-ii is expected to be slightly better. Both would be huge steps up for me.re: upgrading to G9 II for imprved bits - at least based n this, it might be a disappointing upgrade?

The Panasonic G9 II sees a serious upgrade in autofocus -- but is it the best Micro Four Thirds body available?www.thephoblographer.com
If the G9 ii buffering problem can't be solved via firmware fix - then, seemingly, for birding, the OM1Mk2 is the clear choice there between the two. If the buffering problem can be (or has been) fixed via firmware, then it seems like a tougher choice between the two and the G9 has a lot going for it if you're willing to put up with (apparently) slightly lower hit rate during bursts.The OM1-ii is expected to be slightly better. Both would be huge steps up for me.

I get the sony pixels to be 25-30% larger than the OM1 pixels. I guess this would correspond to about 1/3 of an iso step in low light performance if everything else is equal. Not a huge difference in my mind.If you do the calculations, the Sony photsites, even at 60mp FF are larger than the Oly 20mp by a good margin.
What about the Sony a9iii and its global shutter and its 120fps burst mode?If you look at Canon, it is true that the R7 probably is cheaper than the m4/3 offerings. It has relatively slow sensor readout which is one of the reasons it is cheaper: this influences both AF and rolling shutter effects. So for Canon shooters, the faster sensor readout is one of the reasons that the much more expensive FF options are popular. For comparison, the OM1 when it came out had the fastest sensor read-out of any camera available. I do not know that any others match it yet, except perhaps the G9-ii.
If they had the same number of total pixels, I get this statement. But as there are natively > 3x as many of them - that seems like when you can use them that you can likely get considerably more detail out of the sensor, yes?I get the sony pixels to be 25-30% larger than the OM1 pixels.

Remember the crop factor. If you put a lens on each of these two that is truly 400 mm, you are illuminating 4 times as much sensor (in area) or 2 times as much (in linear dimensions) in the FF situation. In percentage of the sensor, you will get a much smaller part of the sensor covered by the bird in the FF situation. To achieve the same % coverage of the sensor, you will need a lens that truly is twice as long in the FF situation, and this makes that lens likely to also be much heavier.If they had the same number of total pixels, I get this statement.

Sony make the M4/3 sensor for OMSystem, yes?
