Here is an exhaustive Canon EOS R5 review, a camera "significant and packed with special…
The hybrid CMOS AF sensor combined with improvements to the stand alone phase detect AF provides the T4i / 650D with one of the most sophisticated focusing systems of any Canon DSLR, particularly for continuous autofocus during movie recording. Coupled with one of the new quiet STM lenses its movie autofocusing is on a par with that offerred by touch-screen mirrorless compact system cameras.
It’s the same AF that is featured on the recently announced EOS M. We wrote before about how much the Rebel T4i/650D was a testbed for the technologies later employed on the EOS M. Camerlabs compares the T4i/650D to Nikon’s D3200. The Rebel T4i/650D gets a “highly recommended” final score. From the verdict:
With the Rebel T4i / EOS 650D Canon has neatly addressed […] issues. The Hybrid CMOS AF sensor improves AF capability in Live view but, more importantly, makes this the first Canon DSLR to provide truly effective continuous AF during movie recording, putting it on a par with Sony’s SLT models and touch-screen mirrorless CSC’s like the Olympus PEN E-P3 and Panasonic Lumix GX1.
Its 3 inch touch-screen […] is intended to pull in compact upgraders and will succeed, but even those who love to use physical controls will find it enhances the handling characteristics in a very positive fashion. Other enhancements, like built-in stereo microphones, 5fps continuous shooting, the Multi shot noise reduction stacking mode and built-in correction for chromatic aberration make the Rebel T4i / EOS 650D an excellent all-round performer and a hard act to beat for first time buyers with a little extra in the budget or those looking to move up to the next level. I highly recommend it.
