I have an unmodded Nikon D5100 that works well with my various instruments. In order to shoot two targets a night, I'm looking to add another APS-C DSLR body and was thinking used Canon due to the availability of clip in filters, BYEOS, etc.
Built in intervalometer, or the ability to use an aftermarket one, is a must.
I'm not opposed to mirrorless and/or micro four thirds.
I'm targeting under $300.
Thanks in advance
