no candle to God, no devil poker! Not a good compromise - at final prices with sane optics, this crop is commensurate with FF! Not suitable for a pro, but expensive for an amateur (and not necessary) Pros below: compactness, quality and set of properties of the crop carcass With its cons: glass, or rather, their absence. There are no high-quality ones at reasonable prices and, apparently, there WILL NOT BE! no dust protection, temperature requirement > 0. "video" button is just ugly
