Talys said:I was trying to say that if you have a focal range constraint -- and I was using 600mm as an example, because this is the biggest lens I own -- there are times when you just can't get enough pixels out of a 20-30 megapixel full frame camera. Because sensor is 1.6x larger, and the pixel density is only a little bit larger, there will be times when you get a gorgeous photo where a bird is just 600 pixels tall, and that's not a usable photo no matter how good those 600 pixels are.
I understand the argument - it's been used for years. In extreme examples, I think the crop might be the best tool, but I don't think the 'crop advantage' as it's called is as often apparent as to make crop a good choice for this reason. Being lighter and cheaper is a much better reason
Talys said:Although I was using eagles as examples, those are pretty easy to photograph using shorter focal lengths and FF cameras because they're such big birds. There are plenty of birds that are much smaller, and often shy, and I just can't get close enough.
I live in the west coast of Canada, where it's often rainy. But birding is a hobby, not a job, so I only go photographing birds on clear days. Mostly, this evolved simply because I like taking hikes in sunshine, not in rainI also don't enjoy trekking in mud.
I mostly photograph smaller birds - there are no eagles where I live! - so I know where you're coming from. But as I say, it is almost never possible to use base ISO, so the crop advantage, such as it is, is even less compelling for me here. I agree it is nicer to stay dry
Talys said:I think ISO 600 photos on an 80D looks grainy, whereas ISO 600 photos from a 5D4 looks pretty good. I have never had the pleasure of using a 5DS, 5DSR, or 1D so I can't say with those. If you don't/can't shoot at low ISOs and you want pictures that are free of digital noise, I'd definitely recommend a full frame camera. If a bird is too far away to get a good picture because of resolution and focal range, c'est la vie -- be patient and pray it comes closer, sneak up if you can, or go and buy a ridiculously expensive longer lens or low aperture lens that you can throw a teleconverter on.
No image is without grain, or free of noise. Of course, we all have different thresholds, but I think there is a tendency amongst some photographers to consider *any* noise unacceptable. I actually add in a bit of artificial grain sometimes - it can help counteract posterisation in out of focus areas, for instance. It's worth pointing out that with Canon cameras it has been useful (though less so now with their most recent sensors) to shoot at a higher ISO and pull the exposure down - ETTR (exposing to the right). I used to think ISO 3200 was the highest I could go on my 5D3 and get usable images. But ETTR and in *some* circumstances ISO 12800 could look fine. It's worth a try if you've not experimented with the technique.
Talys said:An exposure of 1/2500 at f/6.3 ISO 100 does happen. It occurs on a clear day, when the sun is behind you, and you're shooting a bird in flight. It's also the best way to capture the bird's plumage.
I don't agree with this last point. Plumage can look better in flat light; it's partly a matter of taste and style, but high-contrast birds can show more detail with lower contrast.
Talys said:I've never said it's the only way to do it.
By the way, I initially responded because someone posted that people should just give up on APS-C -- that it and EFS are essentially a waste of time. I just fundamentally disagree. As someone who has used both, I've chosen to stay with APS-C for my birding, a conscious choice after wanting to buy a FF camera. On the flip side, I think APS-C and EFS lenses are a great way to get people into photography and ILCs as a hobby, while the investment required to make a decent go of FF is daunting to most.
I think we agree - there's a range of shooting styles, and it's great that there are different options (and useful to hear differing approaches). APS-C is definitely a good way to get into photography; it's certainly cheaper.

Lol, I'm not sure how we got to this point! Although tbh I think these threads are most interesting when they derail a bit. It could be worse - we could be having the old 'Canon is doomed - no they're not, they're the market leader' debate!
