Stunning photos!
Do you know if the OS on this lens is a little more advanced than on the Canon mk ii equivalent?
I've been using the Canon 100 400 ii for perched Kingfishers in low light, and managed sharp shots, hand held, with shutter speeds as low as 1/30 at 400mm.
I bought a used Canon 500 f4 ii from a local shop, as I need more light and more reach, but found to get a steady shot, I needed a far faster shutter speed, so had to boost the ISO far higher than I did with the 100 - 400. Luckily I was able to take the lens back.
I put this down to the extra weight and length, but I sit on a fisherman's low chair, and rest my elbows on my knees for a steady shot, so I'm wondering if it was also partly due to the older IS system of the 7 year old Canon design, and even though the Sigma is a little heavier, does a more up to date OS make it more hand-holdable?
All the best,
Ross.

I can't compare to any Canon system lenses from any personal experience as I use exclusively Nikon gear.  I have no idea how effective of otherwise the Canon 500 F4 II IS is  but I had assumed it would be excellent, surprised to hear that it might not be so good.

The OS on this lens is moderately effective and useful although IMO not as powerful as on Sigma's 150-600 Sport which has extremely effective OS.   I can get away with hand-holding (while using a tree for additional support) the 150-600 Sport down to about 1/15th at 600mm - which is ridiculous!

It's very difficult to say how low anyone could go for reliable sharp photos because hand-holding techniques and capabilities vary considerably.  Your described technique sounds good and perhaps should do as well as I get when using a lightweight monopod.  I don't like to go below about 1/60th sec (with a monopod) and ideally using quiet mode on my D500 to be able to get really sharp results on stationary subjects.  Using pure hand-holding (unsupported) I like to keep to a minimum of 1/250th, preferably faster, although sometimes I can get away with about 1/100th.  Using something like a nearby tree as a support I can also probably get away with about 1/60th hand-held, but again much prefer faster shutter speeds - although that is also because much of what I am photographing is moving!

Not sure whether that sounds good enough for you - I think probably the only way for you to find out whether it will work for you is really try the lens out first hand.   However bear on mind the need to fine-tune AF and perhaps also run through all the customisation options to get the best out of this lens.
