However, a limiting factor of any star-quality system camera is the depth and breadth of lenses and accessories to back it up. Initially, the small selection of full-frame E-mount lenses gave a distinct lack of versatility, but it hasn't taken long for Sony to develop an enticing range of optics that enable the Alpha A7 range of mirrorless cameras like the Alpha A7R III (along with the flagship Alpha A9) to really take the fight to professional DSLRs. >There are still a few holes in Sony's more specialist lens line-up, but they are being quickly plugged. For example, there are no tilt and shift (perspective correction) lens, but Sony's announced the development of a 400mm f/2.8 super-telephoto prime lens that should keep sports and wildlife photographers happy.
