Final Verdict

Sony demonstrates its optical mastery with these two approaches to telephoto work. The 100-400mm GM delivers unprecedented zoom flexibility in a (relatively) compact package, while the 135mm GM achieves near-perfect portrait rendering. Their complementary strengths make them ideal partners in a professional kit covering everything from safari wildlife to studio fashion.

Pro Tip: The 135mm GM focuses close enough to double as a macro-like lens for detail shots, while the 100-400mm’s 0.35x magnification at 400mm makes it surprisingly capable for small subject photography.
