The Canon M50 is a great camera for the videographer shooting wildlife. Criticised for its 2.56x crop factor when shooting 4K video /4K stills this becomes an advantage for those shooting birds and small animals. There's not a lot of native EOS M series lenses available and none with really fast apertures. You can use the EFS lenses, via the EF to EOS M adaptor, which have a better fit to the APS-C sensor or use the full from EOS EF lenses. The EFS lenses are a much cheaper option and the 17-55mm F2.8 lens is a great combination.
The 24M APS-C sensor is absolute torture for older lenses for stills photography however for video, where the resolution requirements are slightly less in 4K, there are some surprising gems out there.
This is by no means a lab test with resolution charts et., more of a real world look at the results.
There are some real bargains to br had on the secondhand lens market. Most APS-C fit lenses will have an adaptor system available to use with either the EOS M mount or the EF/EOS M adaptor.
I chose to use the Pentax K mount lenses as they have a high reputation for sharp lenses. The 50mm F1.7 is a full frame lens and when used on the APS-C sensor gives excellent centre to edge definition.
The 28-80mm f3.5-5.6 also generates some great images.
In this video I look at some of the reasons to use these lenses and also some of the considerations that may make some lenses unsuitable for use with digital cameras.
I'm concentrating mainly on shooting 4K video in this video as this has a slightly less demand on lens resolution compared to still images.
