Tamron lying about the 'smallest and lightest' telephoto lens for full frame E mount

This is tongue in cheek, although the numbers do check out and Tamron is wrong about their claims.

Their lens is 148 mm long, maximum diameter is 77 mm and it weighs 545 grams.

That's certainly impressive, but let's take a look at this gem:

Minolta 100-300/4.5-5.6 APO(D)+LA-EA5

Lens length: 101 mm
Lens diameter: 73.5 mm
Lens weight: 485 g

Adapter length: 31.7 mm
Adapter diameter: 66 mm
Adapter weight: 88 g

So the combination weighs 573 g (barely an ounce more than the Tamron) and is no more than 132.7 mm long (it's actually shorter because lens length includes bayonet flanges which hide within the adapter). The diameter is 73.5 mm.

It's in fact smaller than Tamron's 70-300. Sure, Tamron added a qualifier that its length is lowest among all lenses made for mirrorless cameras. But it's still wrong.

By the way, I'm really hoping Sony would remake something in the spirit of that old Minolta at some point. The lens may be old, but it's incredibly light and compact for what it does.
