Roger Cicala from Lensrentals tested the Panasonic 35-100mm X lens: “At 35mm the lens is awesomely sharp; every bit as good as the 12-35 f/2.8 OIS is at 35mm. There was a slightly different story at 100mm, though, where resolution dropped significantly (100mm mtf50 is 86% of what it is at 35mm, hence the article title). This is still good, but it’s not what I was hoping for.”
Sgoldswoblog also posted some new 35-100mm X lens image samples: “On the basis of today’s experience I’m willing to assert both that the 35-100 is sharp but also that it provides shooting opportunities that wouldn’t arise with primes. Clearly the price for that is a limited low light performance and (subjectively) inferior bokeh.”
The Panasonic X lens is certainly a good quality lens but from these early tests it still doens’t 100% match the exceptional Oly FT zooms. In case you don’t care about the big size than you may be interested in getting a refurbished (but faster and super high quality) Olympus 35-100mm f/2.0 lens at Adorama (Click here) or here at Olymarket Europe (Click here).
