🐈 Canon Extender Ef 2X Iii 70 200 F2 8

Hmm. "EF100-400mm f/4.5-5.6L IS USM + Extender EF1.4x III" is notably absent from the 20fps list, even though the 200-400 with stacked internal 1.4x and external 2x extenders makes the cut. You mention using the EF 70-200mm f/2.8L IS USM "II" lens That works well with the EF "III" Extenders. It might also work well with the EF "II" Extenders, but is not something I've ever tried. (I have use the EF 1.4X II on the EF 100-400mm II with excellent results.) I have no idea how that lens It definitely won't work with either 70-200 RF lens. I've seen this at a number of reputable sources. The B&H page for the RF 2x extender has the following for compatibility: RF 100-400 RF 100-500 (only works 300-500, so you have to keep the lens partially extended while using it effectively making it 600-1000) RF 400 f2.8 RF 600 f4 A 2x is going to significantly degrade image quality, but the kicker is the 100-400 ii at 200mm is sharper than the 70-200 f2.8 ii at 200mm and at 400mm is about the same center sharpness (or better) as the f2.8 ii at 200mm See photozone.de. Clearly the 70-200, f2.8 ii with a 2x extender is not going to be anywhere near as sharp as the 100-400 ii. I have two APS-C (70D and 600D) bodies with Canon EF and EF-s lenses, and Sigmas, among them the Sigma 70-200 f2.8 HSM OS. I am also considering getting the new Tamron 150-600 lens, pending reviews. I was just curious if a Canon extender, specifically the canon EF 2X III, will work on the Tamron and/or Sigma lenses. Versatile 70-200mm zoom range. 3.5-stop Image Stabilizer. USM autofocus. f/2.8-32 aperture range. 1.2m closest focus. Sealed against dust and moisture. 8-bladed diaphragm. Weight: 1480g, Dia x length: 88.8x199mm. .
