Now that optical technology is improving and lenses like the 100-400mm are getting lighter and lighter, carrying a broad-range telephoto zoom lens could make more sense than carrying around multiple telephoto prime lenses.
We are sending a some of our Sony technicians to a famous south west London postcode join the Sony PRO Support team. They be set up nearby to a famous tennis tournament to provide on the spot cleaning, checkups and minor repairs for all the Sony mirrorless cameras and E-mount lenses.
Sony have just announced two releases in their ever growing E-mount lens lineup. The FE 600mm f/4.0 GM OSS and FE 200-600mm f/ 5.6-6.3 are both super-telephoto optics built to withstand the rigours of professional use.
