Pentax FF equivalent 90-375mm f/6

Pentax 60-250mm f/4
Filter: 67mm
Dimensions: 3.23x6.61" (82x168mm)
Weight: 2.29lb (1040g)

And to really drive the point home, the Pentax is for APS/C.

The Pentax is comparable to a 100-400mm class lens, like the Sony 70-400mm or Canon 100-400mm.

Canon 100-400mm f/4.5-5.6
Filter Thread: 77 mm
Dimensions: 3.6x7.4" (9.14 x 18.80 cm)
Weight 3.04 lb (1.38 kg)

So Pentax is a bit smaller and lighter but f/6 equivalent vs f/4.5-5.6.
