We so need a 50-200mm f4.0

A 50-200mm constant f4.0 of high quality wide open and price and size between the Pro 40-150 f2.8 and the 40-150mm f4-5.6.

If the Pro are the new SHG then this could be the new HG.

I have nearly pulled the pin on the Pro 40-150 f2.8 but I need a longer range and something a bit smaller to be happy to carry at all times. For now I find my 50-200 SWD and 40-150mm 4-5.6 plus EC14 and EC20 have a versatility even though clunky and being 4 separate items that I just do not want to swap out for the Pro lens alone or Pro plus 1.4x.

Oh and if a 50-200 f4 also worked with the m43 1.4x then I will fight you to the pre-order counter 😅
