It serves little purpose to reduce the body size of camera if the lens isn’t reduced as well. Fujifilm seems to think this way, since they have released two new lenses along with the X-M1 which sport a really reduced size.
The Fujinon XF 27 mm f2.8 is worth noting, since it has become the smallest lens the company has to offer, with a weight inferior to 80 grams. In fact, Fujifilm has not hesitated to state this is one of the smallest lenses in the market for cameras using APS-C sensors.
With an angle of view equivalent to 41 millimeters, its reduced dimensions make it lack a diaphragm; the adjustment of it should be made from the camera’s controls (something we will need to update the X-E1 and X-Prol’s firmware for).
It features manual focus, with a minimum focus distance of 34 centimeters. Between its lenses, an aspheric element is included, while the lenses feature a special coating named HT-EBC.
Fujinon XC 16-50 mm f3.5-5.6 OIS
Despite fixed focus lenses are still dominant in Fujifilm’s catalog, lenses with zoom are increasing in number with the recent release of the Fujinon XC 16-50 mm f3.5-5.6 OIS. With a more modest specs in regards to lenses and luminosity than the XF 18-55 mm f2.8-4 R LM OIS, it’s the first with the XC denomination (up until now, all the lenses from Fujifilm’s X system were identified as XF) and it’s presented as the perfect couple for the small X-M1.
With an angle equivalent to 24-76 millimeters, this stabilized zoom features a structure made of 12 elements organized in 10 groups, including 3 aspheric lenses and a low-dispersion element.
New firmware and "peaking focus"
Along with these new features, Fujifilm has also announced a firmware update which will allow the X-Pro1 and X-E1 to control these lenses without a diaphragm ring.
This new firmware, version 1.06 for the X-E1 (available today) and the 2.01 for the X-Pro1 (available July 23) promise features to improve the performance of the automatic focus and also enable the “peaking focus” function for manual focus (something already seen in the X100S and the X20), as well as some other configuration functionalities.
