crystal quartz or a ceramic resonator • RF: internal feedback resistor • RExt: external resistor to limit the inverter output current • CL1 and CL2: are the two external load capacitances • Cs: stray capacitance, sum of the device pin (OSC_IN and OSC_OUT) and the PCB (a pa...
However, all numerals and lettering on its barrel are just printed, not engraved, which is a pity considering the elevated price this lens commands. Its optical design includes rear element (RF) focusing, which is a special case of internal (IF) focusing, so the length of the lens won't...
A Super-Sonic motor inside the lens delivers very fast and relatively quiet AF. The lens weighs 460g. This lens is only available for the Nikon F mount. It directly attaches and is fully compatible with all Nikon F mount cameras with APS-C (1.5X) sensors. Focal-Range 8mm800mm 10-24mm...
