Ricoh Imaging has released a firmware update for the recently-launched Pentax K-70 DSLR camera.

The new Firmware Update Software Version 1.10  adds the ability for ISO sensitivity to change during multiple exposures and provides ‘optimised’ performance when the new HD Pentax-DA 55-300mm f/4.5-6.3ED PLM WR RE lens is fitted. It also provides improved stability for general performance. The new firmware can be downloaded from
