Tamron 50-400mm F4.5-6.3 Di III VC is the latest releases Super-Telephoto Zoom lens for the Sony E mount, compatible with full-frame Sony FE mount cameras. The 50mm on the wide end makes this a very attractive lens many people due to its versatility compared to 100-400 lenses, so it has the potential to be a very popular lens amongs the E-mount shooters. In this review, we will be comparing the Tamron 50-400mm with the Sony FE 100-400mm F4.5-5.6 GM OSS and the Sigma 100-400mm F5-6.3 DG DN OS lenses for the E-mount to see how these three options do against each other, starting with the real life scales size comparison: (Bonus: For APS-C shooters, check the section at the end of this post for the comparison with the Sony E 70-350mm F4.5-6.3 G OSS)
Tamron despite its wider range is the most compact of the three lens, kudos to Tamron engineers. Yes the Sony is a little faster on the tele-end with f5.6 vs the f6.3 of the Tamron but still, Tamron is a 8X zoom lens vs the 4X of the others, we can't expect miracles.
And now we have a feature and spec comparison to help you further with your decision:
What stands out beside its compact size is the huge 0.50x max magnification ratio! This gives the Tamron a big close-up capability only bested by the dedicated macro lenses.
Price wise, the Tamron 50-400mm with an MSRP of $1299 is located somewhere between the other two lenses where the Sigma 100-400mm sells for $849 and the Sony 100-400 sells for a whopping $2499!
The 50mm on the wide end, relatively compact and lightweight body combined with the reasonable price for this class makes the Tamron 50-400mm F4.5-6.3 Di III VC a great choice for many E mount owners!
