Ok received the S5ii with 20-60mm and 50mm lens kit this morning, charged the battery had a very quick play and then took it with me on a shoot this afternoon - nothing too taxing or crazy, just filming speakers at a conference and took some photos in between.
Was able to use it instead of the Canon R6 until it ran out of battery (only had the one, lasted about as long as R6 battery does - couple of hours in 4k). Here are my thoughts so far...
Some real positives over the R6 for this type of work -
No 30 minute limit (one of the talks was 40 minutes) so was nice to capture it all
Able to use my 7" monitor whilst having full access to the cameras touchscreen - this was lovely and so much more relaxing for my ageing eyes. Great to be able to put lut on monitor and also use full HDMI - even without a cage felt more reassuring than horrible micro
No overheating whatsoever in 4k 10 bit 422 for 2 hours - priceless for peace of mind. Once the battery ran out had to use the R6 and overheating warning came on in the last hour so changed recording down to HD for the last speaker
Comparing to the R6 they are very similar in size and weight - S5ii feels very solid, R6 a bit plasticy in comparison although slightly nicer grip in the hand (was marginal though and maybe dependent on hand size). S5ii AF with the 20-60mm and 50mm 1.8 seemed to stick well once it locked onto a face. Nothing very taxing but did a good job I think - will need to check through all the footage but am pretty confident it worked as well as the R6 under these conditions
Audio - used Sound Devices mix pre-d at line level 96khz 24 bit into the S5ii - seems to capture a clean sound, need to do some testing but think it is a step up from the R6
The 20-60mm lens is probably the best kit lenses I've used - well made, nicely dampened focus ring and zoom. Love that it's 20mm on the wide as opposed to standard 24mm, don't think I'll need any wider. Bit short on the long end but used it in apsc mode - quality seems a little sharper than the r6's crop mode but am only eyeballing off the screen
The 50mm 1.8 is really nice, completely silent AF, nice size and lovely feel to the large focus ring, also quite pleasing bokeh from first impression, felt like a quality lens - obviously in a different price bracket to the Canon 50mm STM lens but yes a lot nicer to use
That's all for now, feel like it could be a good purchase though of course early days so time will tell, used vlog and am just trying some luts in Resolve now - looks pretty good for conference type lighting
