Photo-objective lens attachment Opteka 10x High Definition II Professional Macro Lens
Lets look on photo-objective lens attachment Opteka 10x High Definition II Professional Macro Lens. When it is added to photo-objective lens, it receives macro functions ( allows to make magnified photos of objects ) and its zoom is increased 10x times. It is attached to photo-lens via 52 or 46 mm thread, there is ability to attach 52 mm optical filters to it on frontal side. Wherein there are variations of this lens with different diameters : 55, 58, 62, 67, 72 and 77 mm. Attachment contains 4 lens elements, that are made of low-dispersion glass, all of them are coated with protective and anti-reflective multicoating. Its body is made of metal to increase its durability. It supports auto-focusing of objective lens and does not cause problems for infra-red shooting. There is need to note, that attachment’s lens elements has 40 mm diameter and on photo-lenses with large frontal glass it can obstruct part of scene; in this case there is need to reduce lens diaphragm, so that it will not produce image artifacts. Package contains : Opteka 10x High Definition II Professional Macro Lens attachment itself, frontal and rear caps, carrying and storage pouch and 5-years warranty card. In general, it is interesting solution, which costs much less, than specialized macro photo lens; but before its purchasing there is need to read in Internet information about how it works with given photo-lenses models. It has 4 lens elements and together with photo-lens this can produce large amount of optical surfaces, this increases light dispersion and internal reflections, so it is desirable, that base photo lens would have small amount of optical elements.
Today among audio devices we will look on MIDI keyboard M-Audio Keystation 49 II USB. It is DAW parameters controller and MIDI notes recording instrument. Overall process looks like so : human plays on this instrument and controls various parameters, they are recorded by DAW in MIDI editor, then they are played by software synthesizer. Keyboard has 49 full-size keys, which react on press velocity ( it is very useful, because many synthesizing parameters can be controlled with press velocity, this allows to perform these actions faster and more creatively ); has USB and MIDI connectors for communications with computer; is powered from 1 USB port; has different buttons and knobs for DAW parameters controlling; has small weight ( this is useful for its use on concerts ); and can be plugged to iOS devices via Apple iPad Camera Connection Kit adapter ( which is not bundled with MIDI keyboard ). With M-Audio Keystation 49 II USB controller following software is supplied : SONiVOX Eighty-Eight Ensemble – sample based synthesizer-emulator of piano 9-foot CD327 Steinway ( it has in itself recorded samples of this instrument, from which it can synthesize different sounds of this instrument ); DAW Ableton Live Lite; and multi-functional AIR Music Tech Xpand!2 synthesizer. Keyboard can work with Windows XP, Windows Vista, Windows 7, Windows 8 and Windows 10 and Mac OS X 10.5 and newer operating systems; it integrates very well with modern DAWs : FL Studio, Cackewalk Sonar, REAPER, Avid Pro Tools, Ableton Live, Steinberg Cubase and others.
Attachment lens for photo-objective lens Polaroid Studio Series .43x High Definition Wide Angle Lens With Macro
Lets review attachment lens for photo-objective lens Polaroid Studio Series .43x High Definition Wide Angle Lens With Macro, when it is added to photo lens, it receives wide angle and macro characteristics. It is attached at frontal side of lens into 58 mm thread, there is ability to add to attachment itself 62 mm optical filters to its frontal side. It works with zoom objective lenses and can be used for photos shooting in infrared range. Attachment minificates image by 0.43x times. There is need to note that lens is quite big and can obstruct built-in flash of camera. All in all : it is good solution for optimal price and allows to receive wide angle lens with macro with small amount of lens elements, if main objective lens have their small amount. Wherein specialized wide angle macro lenses are engineered to reduce amount of geometrical and chromatic distortions and usually produce better image, than photo-objective lenses with such attachment. But there is possibility, that photo lens and attachment will fit together very well and will not produce noticeable amount of distortions : this depends solely on them.

Lets continue our acquaintance with DAW REAPER : today we will learn VST ( Virtual Studio Technology – is a technology for plugins creation, which act as instruments, effects and processors, and for their unified connection to different DAWs and other programs ), work with recorded sounds and rhythm of composition. For this purpose we will create simple example, for rhythm we will use recorded sounds of snares and hats; simple melody we will create with use of VST synthesizer Genobazz 2, which was created by TEK’IT Audio. You should already have installed DAW REAPER, if you have some difficulties, you can write about them in comments, I’ll answer to you as soon as I’ll have free time. VST Genobazz 2 can be downloaded from Internet, it is a free plugin; you can find links to it in Google. It is distributed in form of executable installer; create somewhere VSTs folder, in which you’ll install plugins, they can be used by other DAWs also, so it is better to place it on path, that is accessible by all programs. Then install Genobazz 2 in this folder; then open options page in DAW REAPER Options -> Preferences ( this window can be seen on upper image ); choose VST in left list, add path to you VSTs folder in according field and press Clear cache/Rescan, so that DAW will find and install this plugin. Then download archive with project example and open it in REAPER.
DAW REAPER : Rhythm and basses
As it can be seen from the image, rhythm is created with use of recorded sounds ( they are located in project archive ). All sound files can be inserted into tracks by dragging and dropping them from Explorer into DAW, it will import and setup them by itself. Basses are synthesized with use of MIDI notes, for them I selected two sounds presets ( preset sound synthesis parameters ) of Genobazz 2 : Defaul and Acid Tweet Arp. VST plugins can be added to track by clicking on FX button; then on Add add button and by selection of VST ( for effects and processors ) or VSTi ( for instruments ). REAPER also supports other plugins formats and its own scripting language for sounds processing. Order of plugins matters, because sound signal is passed from current plugin to next one, this way sounds processing chains can be created, for example : synthesizer receives MIDI notes and generates sound, which later is processed by effects, so that needed sound will be obtained. VST plugins can be added to MIDI tracks and to tracks with recorded sounds. MIDI notes can be edited by double clicking on their panels in track; to the left on their editing windows musical keyboard is located, at the bottom part there is area in which other notes parameters can be edited, for example, velocity of keys pressing ( whether these additional parameters will be accounted by synthesizer : depends solely on itself ).
DAW REAPER VST Genobazz 2
This project example is very simple and there is ability to experiment with it, creating composition, which you like. For example, there is disabled track, which can be used to create rhythm with kicks and receive House music rythm; all in all, here is ability to unleash your imagination. That is it for today; if you have any questions, you can ask them in the comments, I’ll answer to them as soon as I’ll have free time for this. See you in the next article about DAW REAPER.
Lets review Audio-Technica ATH-R70x novelty, these are the professional studio monitor headphones with according characteristics. They have : 45 mm drivers, powerful magnets with fully metal housing ( which provides construction stability and provides clear high frequencies reproduction ), 5 – 40000 Hz sounds frequencies reproduction range, 1000 mW maximal power input, 99 dB sensitivity and 470 Ohms impedance ( such high impedance requires powerful signal, which makes all cable noise signals very week in comparison with it, and also it does not allow all noise signals to go to electric coil near magnet ). They had open back architecture with aluminum honeycomb mesh housing and composite resin and plastic materials for construction rigidity, which make sound reproduction more clear. They weight 210 g and have cozy pads and wing, which make their long use comfortable, which is important with their use in studio. Cable of headphones is pluggable, wherein, it does not matter how it is attached to pads, because right signal is automatically chosen for each pad. Package contains : Audio-Technica ATH-R70x headphones themselves, pluggable cable, protective carrying pouch and user’s guide. All in all : these are the very interesting headphones, but they are not suited for home use, because they cost very much and their high characteristics are not needed for home use. But, if there is choosing : buy too branded audiophile headphones, for which 2/3 of cost are costs for brand name and marketing expenses, and these ones, then it is better to buy these ones.
External studio sound card Focusrite Scarlett Solo
Among audio devices today we will look on external studio sound card Focusrite Scarlett Solo. It is designed for analogue audio recording on semi-professional studio level. Its front panel has : microphone XLR input with Focusrite preamplifier, +48 V phantom power switch and amplification level control; instrumental/linear 6.3 mm TRS jack ( 1/4″ ) input, instrumental/linear switch and signal amplification level control; 6.3 mm TRS jack ( 1/4″ ) output for monitor headphones, Direct Monitor mode switch and headphones volume level control. Its back panel has : 2 analogue linear RCA outputs; USB port, through which it communicates with computer and receives power from it; and Kensington Lock slot. Card works with 44.1, 48, 88.2 and 96 kHz sampling rates and 24 bits precision.
Microphone input has following characteristics : 106 dB dynamic range, -125 dB noise volume level; instrumental input : 106 dB dynamic range, -109 dB noise level; linear input : 106 dB dynamic range and -98 dB noise level; linear outputs : 106 dB dynamic range, -97 dB noise level; and monitor headphones output has 106 dB dynamic range. Body of card is produced from aluminum and has beautiful maroon color. Drivers are released for card for Windows XP and newer and Mac OS X and newer operating systems, which allow it to work with modern DAWs : Ableton Live, Steinberg Cubase, FL Studio, Cackewalk Sonar, REAPER, Avid Pro Tools and others. Card is supplied with following software : DAW Ableton Live Lite, Focusrite Scarlett plugins package, Novation Bass Station plugin and 1 GB of Loopmasters sounds samples. Package contains : Focusrite Scarlett Solo sound card itself, USB cable, optical disks with drivers and software and user’s guide. In principle : it is a good middle-level sound card with more or less optimal price for its functionality; it has good dynamic range and noise level characteristics of analogue inputs and outputs. But, there is need to note, that for 125 USD ( card’s price at the middle of Autumn 2015 ) there is ability to buy more functional card or there is ability to buy card with similar functionality for smaller price. Also : it has no MIDI and digital inputs and outputs, but this can be solved with additional cheap internal or external audio card with such ports.
LZOA MC Rubinar 10/1000 Macro as objective of small telescope
Lets continue reviews of Soviet and Russian made objective lens for M42x1 mounts with LZOS MC Rubinar 10/1000 Macro device. It is very powerful telephoto objective lens with 1000 mm focal distance, 1.9 kg weight and 125 x 210 mm sizes. Its aperture equals to f/10, because of this it is not very light and more suited for shooting of objects on land and for shooting of bright astronomical objects. Its field of view is 2.5 degrees and focusing distances range is 4 m – infinity. LZOS MC Rubinar 10/1000 Macro has M116x1 mount on frontal side for optical filters and other accessories. It has 7 lens and mirrors elements in 5 groups ( which is very good ), all of them are coated with protective and anti-reflective multicoating. Also, LZOS MC Rubinar 10/1000 Macro can be used as small telescope, which is not surprisingly, because its optical scheme is very similar to Macsutov-Kassegrene telescope. For this purpose special converters and eye-pieces can be used ( previously LZOS even produced kits, which allowed to use lens as photo camera objective lens and as small telescope, such kit can be seen on photo ); also, this can be achieved with use of special converter with M42x1 mount on one side and 1.25 or 2-inch eye-piece focusing unit on the other side. 2-inch module and eye-pieces are preferably, because they allow to fully reveal capabilities of lens. Currently LZOS does not produce those lenses ( which is pity ) and they can be bought only in stores, which still have them in storage rooms, or through private ads. All in all it is a great objective telephoto lens and, if you have no telescope with similar characteristics, it is good candidate for this purpose, which can be used as multifunctional device. But if you have telescope, then it can be also used as camera lens with use of T-ring.
