After enjoying the use of my 75-300 at Yellowstone last month, and looking at everyone else with Canon and Nikon 600 and 800mm gear, I'm happy to see the size, weight and designed mtf of the 100-400. That's now on my list.
Glad for you! Indeed! It certainly looks a great bargain lens for such committed use! Even more so looking at the MTF diagrams vs the cost. I am sure many folks will be delighted with this lens for such use vs the alternatives so far. Surely a lens great to use a full day long in such great enviroments.
A better 75-300? That is f6.7 at 300mm. The 100-400 is f6.3 at 400mm. It has to be larger in diameter for that to happen.
0.4? Who cares? A stop and more, yeah we can argue on that. But is it that wide and long because
2/3s of this lens are scaled for an FF sensor image circle? At that price and the above use, who cares? For my daily living use, nope, it is just too big to haul along as I always do with the 75-300 in my bag wherever I go in daytime.
You couldn't add a $30 grip to your E-M10ii?
A grip attached is a grip that usually stays there so why get the petite EM10 in the first place? And if I go over to the E-M1 size it may not go along the X100 in the bag but instead stay at home to keep company to that 100-400 that —>
Sorry, but you don't have to buy it.
—>I’ll never buy.
So now YOU have to buy TWO of them to make up the marketing losses for the NewCoOly ?.
Maybe the Pany 100-400 will be my first Pany lens... hmmm, no Sync-IS with my future M5iii, no repairing possible, stories of machining irregularities... nah, the 75-300 is here to stay! Better stop reading this thread as it gets nowhere for my needs. A Pany body? Only one I liked was the GX8 and they killed that line.
