Limitations
• Some EF-S and DX lenses may not have enough coverage of the entire image circle for stills after widening by 0.71x (but video will have enough coverage).
• No video AF for Olympus
• AF may not work if the maximum aperture of the lens plus any EF extender or other teleconverter attached is smaller than f/8 before boost or smaller than f/5.6 after boost.
• AFC (continuous AF) and AFF (flexible AF) modes are not supported, except on Olympus OM-D E-M1.
• Panasonic video AF may hunt more than a native lens or have unsatisfactory performance.
• Some Tamron lenses may have unsatisfactory AF accuracy.
• No support for Focus Stacking and Focus Bracketing on Olympus.
• On Olympus, other than E-M1, you may move the single AF point among any of the 81, but you may not multi-point AF. There is no restriction on E-M1 and Panasonic.
• Very early Olympus models (e.g. E-PL1) have no autofocus support.
• EF-mount lenses are not silent but may make audible click noises during autofocus operation and iris changes which may be picked up by the built-in microphone of the camera. An external microphone is recommended for video.
• Use of Canon Cinema lenses such as CN-E 18-80mm T4.4L IS KAS S for still photography is not supported.
•Iris changes are in 1/8 stop steps which may be noticeable in video recordings. Programmed exposure mode and shutter priority exposure mode should not be used for video. This limitation does not apply to Cinema EOS lenses which permit fine resolution iris control, such as CN-E 18-80mm T4.4 L IS KAS S.
• No support for in-camera correction such as peripheral shading, CA and distortion
• Designed to cover a 24mm image circle, JVC GY-LS300 needs to have VSM configured to 86% (4k) when using a true Super 35 lens such as Canon CN-E 18-80mm T4.4L IS KAS S. Higher VSM settings is possible with full-frame lenses, but will be operating outside of the design parameters of the ULTRA optical formula. Many APS-C/DX lenses do not have adequate coverage at 86% (4k) and on JVC with ULTRA the use of full-frame or true Super 35 lenses is advised.
