Hope not!
Imho this new RC paper is terrible. It's basically Kentmere RC... but sold at premium Ilford price. It's very hard to get decent grays with this MGV while the "old" MGIV would deliver lovely delicate grays.
If you use the MGV to make contact prints, any picture that was overexposed will be rendered a a blank white indecipherable rectangle. With the MGIV paper you could at least see bits of details.
This is
NOT Kentmere under a different name. I doubt if you have the technical knowhow or insider information to make a sweeping statements!
I have both in my darkroom and there is a world of difference The Kentmere fibre has not sold for a number of years (I have a few 12x16 sheets and half a box of 5x7 left) and a box or two of the current RC. The old Kentmere factory was operating under some quite questionable Health and Safety conditions so the old emulsion had to go and apparently not profitable.
Compared to both Kentmere papers, the tone of MG5 is warm almost verging on a chloro-bromide - but not quite. The tones of MG4 fibre based was as neutral as anything else I have seen, but the tones of the Kentmere RC is 'cool', but not so much as Ilford cool-tone.
In addition, MG5 is about 1/2 a stop faster than the old MG4, where as I find Kentmere both RC and fibre are about twice as sensitive as the old MG4
The contrast variation conveyed by the new emulsion is designed to give more even steps in the different grades. (Ilford public statement, not my idea plucked out of the ether.)
So saying the MG5 is a reincarnation of the Kentmere is complete and utter rubbish. They are as different as chalk and cheese
