DPReview has released their Canon EOS R5 and R6 test of overheating, using the final production models. Technical editor Richard Butler remarks “Lack of dependability makes them a poor choice for much professional video work”.
The Canon EOS R5 is a faulty product. If you are order an EOS R5, please consult the field tests and data below to determine how it performs in the real world.
Canon are marketing the EOS R5 and R6 as reliable filmmaking tools that professionals can depend on during a shoot.
As we have seen from field-tests of both cameras, overheating nightmares demonstrate this just isn’t the case even on short shoots in high quality 4K 24p. The reliability issues are so serious that paid professional work is a complete gamble in 4K on both models.
Even the EOS R6 with the lower 20 megapixel sensor at the lowest frame rate (4K 24p) suffers repeated shut downs on a short shoot. In my opinion, this is a problem for Canon so severe it may even result in a full product recall and a class action lawsuit.
Let’s have a look at thermal management on small mirrorless cameras. The solutions shown here prevent overheating on the Sigma Fp and Panasonic S1H during long recordings. The Sigma Fp shoots 4K RAW internally from a 6K sensor and the Panasonic S1H shoots 6K internally in 10bit 4:2:2 V-LOG.
Canon can learn from the design of the Sigma Fp and Panasonic S1H when it comes to offering professional video features in a small weather sealed body.
With the price of the EOS R5 set at £4199 here in the UK, that is firmly pro-territory, but Canon has an enthusiast version too which will be the focus of many at EOSHD. The Canon EOS R6 is a competitor to the Sony A7 III, Panasonic S1 and Nikon Z6. It brings 10bit to the table over the 8bit only Sony & Nikon – and Dual Pixel Autofocus to the plate which is an advantage over the Panasonic cameras.
Canon users will also like the fact that the EOS R6 at $2500 / £2500 puts a lot right for video users compared to the disappointing first EOS R.
Sony has confirmed that the A7S III is finally on the way this Summer, likely in July to coincide with the big Canon rivals – EOS R5 and R6.
I have some more information on what we can expect from the new flagship full frame mirrorless cameras.
Yesterday all sorts of rumours started flying around about an EOS R5 with unbelievable video specs. A dream camera. I didn’t believe it. However, further digging by users of the EOSHD Forum, reveal Canon are officially on the record – an 8K EOS R is coming. As well as this, there are some interesting technical aspects in the alleged “leak” which – despite the unbelievably high specs – do actually add-up.
