  Wow, what a test. To compare an existing - with a non existing lens. That
doesn't happen that often. He probably has a whole cupboard full of non existing
equipment, for which he paid a fortune. Hell compare all the other  real
equipment he receives, to the ones in his  (empty) cupboard.

This may be the latest way of reviewing anything and everything.
Example: The new Toyota Corolla is al lot cheaper and most probably faster, than
the equivalent Ferrari.

Then again, the guy may just been on drugs that day, or just plain drunk, or
couldn't think of anything sensible to say to fill up his paper,  or,  and
that's my guess: He is just plain stupid.

Now to the actual review:

Optical quality:           28/30--- 28 out of 30. that does not give us much
room for future          improvement. The 30 out of 30 will soon be reached.
what then?

Ease of use:              27/30

Construction quality:  19/20---  Boy 19 out of 20. What does he give the 1950
and 60's
Leica lenses/  25 out of 20.

Value for money:        18/20--   this is a subjective measure. If I want and
need a 12mm
lens, then it is 20/20, if I don't its a lot less.

Really  if one has to use a number system, then I could maybe understand 10 or
12 out of 20 for a test. But 18 or 19 out of 20, does not give a true picture.
It  implies, that in future hardly any improvement can be made.

If this bloke was around in the 1950's, he would have given the Summicrons and
Summiluxes 19 out of 20. What about the large improvements since? It would not
fit in to his numbering system.
