Among photo-lenses for Fujifilm X mount there is novelty appeared – Fujifilm FUJINON LENS XF35mmF2 R WR, it is protected from dust, water splashes and low temperatures ( can work at temperatures higher than -10 degrees on Celsius ) and has quick auto-focusing ( 0.08 s ). Its 35 mm focus is fixed; diaphragm can be set in f/2 – f/16 range via 9 diaphragm blades; field of view is 44.2 degrees; it is designed for APS-C sensors; and its minimal focusing distance is 0.35 m. Lens does not support optical image stabilization ( camera can perform it by itself via sensor shifting or digitally, if it supports it ). 9 glasses ( 2 of them are aspherical for geometric and chromatic distortions reduction ) in 6 groups are built into it ( it is relatively high amount of lens elements for fixed lens ), all of them are covered with protective and anti-reflective Nano-GI multi-coating. 43 mm optical filters can be attached to it, its sizes are 60 ( diameter ) x 45.9 ( length ) mm, and mass is 170 g. Package contains : Fujifilm FUJINON LENS XF35mmF2 R WR itself, frontal and rear caps, carrying and storage wrapping cloth and users guide. In a whole, this is a good photo-lens with interesting functions ( auto-focusing, protection from dust, water splashes and low temperatures, built-in aspherical lens elements and others ), which is useful for photos and videos making ( especially if camera supports image stabilization ). Wherein, if there is no need in auto-focusing, then there is ability to buy cheaper lenses with better optical characteristics, including lenses for other mounts, which can be used via adapters and converters.

Package contains : Sony Cyber-shot DSC-RX1RM2 camera itself, USB cable, power adapter for battery recharging, optical disks with software and user’s guide. It is very specialized camera, that is mainly designed for macro-photos making with very big resolution;, because its lens is mounted and fixed; wherein it costs 3.3 thousands USD; so, if there is no need in its specialized functions, then it is better to buy semi-professional camera with interchangeable lenses for much smaller price and receive high-quality photos and videos.
Review of new monitor headphones Sennheiser HD 598
Lets review new monitor headphones Sennheiser HD 598. Manufacturer does not tell information about diameter of their drivers, but, judging by their view, it is 40 mm, they are driven with neodymium magnets and can reproduce sounds with 12 – 38500 Hz frequencies, thier impedance is 50 Ohms; manufacturer does not tell information about their sensitivity and signal to noise ratio. Package contains : Sennheiser HD 598 headphones themselves, TRS 6.3 mm jack – 3.5 mm mini-jack adapter and user’s guide. Overall, they are too overpriced ( 250 USD at the end of Autumn 2015 ) : in the technical details ( which not all are disclosed ) they are not better and in some respects even weaker, than top-level monitor headphones of Sony and Philips and cost much more, than they are; and for less than half of this sum professional studio monitor headphones can be bought, which are far superior in sound quality respect, than this handcraft. So, this is a classical example of marketing money pumping from customers with use of loud claims and names, which mean not much in technical respect; so, these headphones are not recommended for purchasing, it is better to buy top-level monitor headphones of other manufacturers with known technical details or professional studio headphones for much smaller price.
EHANG launches new flying GHOST DRONE 2.0 for photos and videos recording
Lets review new flying bot EHANG GHOST DRONE 2.0 for photos and videos recording, which will be available in shops from 31st December of this year.

Bot can be controlled from Android or iOS smartphone with use of special device G-Box ( which is included in package ), it connects with smartphone via Bluetooth connection and allows to control it via special application. Transmitter range is 1000 m, in case of connection lost or low battery charge it will return to starting point. One battery charge is enough for 30 minutes of flying, it fully recharges in 60 minutes; it supports following flight modes : Waypoint Mode, Companion Mode, Avatar Mode and Fly Planning. Mainly bot is designed for minimal flight control experience of operator and performs stabilization in air in automatic mode. This is interesting drone model for photos and videos recording from air, but its price is too big, in comparison with competitors, which for the same money offer bots with similar or better flight characteristics and camera in package. So, for this price this model is not recommended for purchasing, maybe, after some time after release, manufacturer will lower its price under competitors pressure and for lower price this bot can be quite competitive.

Review of new Beats Powerbeats2 In-Ear Headphones
Lets review new Beats Powerbeats2 In-Ear Headphones. Manufacturer tells nothing about their technical details, so this already rises suspicion. Judging by their view, 8 or 10 mm drivers are built into them, tips have additional hooks for better weight distribution and better fixing on ears, cable length is 119 cm and mass is 26.7 g. They are protected from sweat and moisture, volume control unit with microphone and phone remote control buttons is attached to cable. Package contains : Beats Powerbeats2 In-Ear Headphones themselves, carrying and storage case, 4 interchangeable tips of different sizes for comfortable wearing by different people, cable fixing clip and user’s guide. All in all, taking into account lack of technical information ( frequencies range, drivers diameter, magnets, impedance, sensitivity and maximal input power ) and very hight price ( 199 USD at the end of Autumn 2015 – for half of this sum there is ability to buy profession studio monitor headphones and for much smaller money amount there is ability to buy very good in-ear headphones with known technical details ), these headphones are not recommended for purchase.
