Hi Klaus,

 

Thanks for putting this together!

 

However, there were a few things that I believe should be mentioned.

1) selected lenses for FF and µFT are for mirrorless while Pentax lenses for APS-C are for DSLR (leave out K-01 which takes DSLR lenses w/o adapter). For telelenses you can argue that this is in favour of DSLR because of the shorter construction of the lens only.

2) as you rightly said, the Pentax DA* 60-250/F4 doesn't really fit but if you replace the Sony FE with Canon/Nikon/Sigma 80/100-400 F4.5-5.6 which is more the range of the Pentax, you quickly end up in the 1340-1750 g range which is more than the Pentax lens even when correcting for slightly faster lens at lower focal lengths.

3) when selecting a more traditional focal length for telezoom (70/80-200) the situation between FF and APS-C also looks different:

Pentax DA* 50-135 F2.8 - 685 g; 136 mm long vs Canon 760 g; 172 mm long

 

Besides the very informative text, your lens selection goes more in a mirrorless vs dSLR rather than a sensor size comparison.

1) : sizes of lenses only matter for bag space purposes. In that sense it makes no sense to point out the mirror box difference?

2) : the Pentax f4 lens is slower of the whole range (f6) in equivalence terms. So its weight advantage compared to a f4.5-5.6 lens would be due to that, making it a wonky comparison too.

Klaus could also have chosen one of the many 70-300mm lenses for FF DSLRs, the choice for the FE lens is fine and not a mirrorless vs DSLR skewed choice.

3) : A Pentax f2.8 lens is slightly slower (f4.2 FF equivalent) and the Canon EF 70-200mm f4 L USM weighs 705 grams. Which goes to show, one can always skew things in whatever favour (do you happen to shoot Pentax?).
