Changed ND filter ND filter with 4 levels Electronic Variable ND filter from ¼ to 1/128
Changed E Mount Standard E mount E mount locking mechanism
Improved Colour space Rec 709 Rec 2020 (same as F5) so get better colours
Added Power LED NA Above the on off switch to show if the camera is on
Thumb Screw on grip arm extension Required a screw driver No screw driver required to control
Assignable User buttons 6 10
Changed Recording card holder Sticks out 4.3mm more for easier removal
Changed big viewfinder loupe One of the two flimsy loupe attachments has been removed. They also added a nice foldable sun hood as an alternative to the loupe when using the LCD in sunlight.
Changed LCD attachment The round rod with a square one, so the LCD doesn’t tilt so easily.

What hasn’t Changed

Super  35 sensor, 4k DCI resolution upto 60fps, internal Slo mo till 180 fps,

Electronic Variable ND filter

While the FS7 has 4 levels of ND, The FS7 II gets the an electronic neutral density filter which is continuously variable from 1/4 to 1/128 strength. It can also be completely disengaged when unneeded and is automatically replaced with a clear glass.

 

The Electronic ND works in 3 ways

1. You can preset the four-position filter wheel to whatever fixed discreet levels of ND you want – in a similar way to the way you can assign values on the gain switch on other models. This allows you to work in much the same way as you would with a conventional ND filter wheel, with rapid ND changes if you need them.

2. Alternatively you can use a thumbwheel to vary the ND continuously, through seven stops of correction. This is essentially a better version of a front mounted variable ND filter, but without the drawbacks.

3. You can use automatic ND for auto exposure without varying f-stop, gain, or shutter speed. The electronic neutral density control doesn’t affect the color the way a regular ND fader filter on the front of a lens does, and it quickly becomes your primary exposure control, allowing you to work at a constant aperture in almost all situations.

E mount locking Mechanism

 

The innovation about the E-Mount Lever Lock mechanism makes it very similar to the PL mount system used in cinema productions: instead of turning the lens you now turn the collar.

 

This helps lock lenses more tightly and is ideal for large camera setups such as when you have a matte box and follow focus setup, as you don’t need to twist the lens.

This mount is ideal for cinema, large lens setups and also when the camera is on a tripod but could be challenging to use single handedly.

 

Tool-less operations

The FS7 II’s “tool-less” mechanical design lets users make on-the-fly changes to the camera’s set-up and operation. For example, no tools are required to adjust the Smart Grip or viewfinder positions

 

Changed Microphone mount

 

The microphone mount is now runs on a 15mm rod, rather than being fixed on the rod as on the FS7. The mount has been modified for better noise isolation from handling. The new mount allows you to use a microphone either on top, or slightly underslung closer to the lens.

 

Changed View finder mount

The viewfinder mount’s front and rear adjustment has been changed from a round rod, to a very slightly longer squared-off tube that will ensure that the viewfinder stays in a horizontal orientation. The earlier circular rod has been provided for users preferring the old one.

 

In the nutshell, a few changes making it primarily useful for feature film makers. Documenatry and smaller film crews will continue to prefer the older version

 

 

Zeiss Exo lenses pros and cons

The good

The Zeiss name lives upto its standard.

The Iphone lenses deliver excellent photo quality & video quality.

No artifacts and great sharpness. No distortion and vignetting.
The lenses are well constructed in aluminum and glass. The frame to hold the lenses is sturdy.
The bad

The screw mount can be awkward for quick swaps.

The bracket mount blocks the camera’s flash and

you’re bound to lose the tiny back caps. And they’re pretty expensive.
The bottom line

Great lenses that have increased the flexibility of shooting on the Iphone. A great set of lenses for serious photographers who are ready to spend. The lenses will be a big boon for guerilla film makers, people web streaming using iphones etc.

 

Zeiss EXO lenses for the Iphone

Thursday, December 22nd, 2016

The old saying “you get what you pay for” definitely applies to Zeiss’s new ExoLens system.

The lenses are all sharp, with no light loss or color artifacts. It combats nasty problems like distortion, vignetting and chromatic aberration. As you’d expect, the lenses are well constructed of aluminum and glass. In fact, with their bundled lens hoods attached, they look like a set of miniature of the Zeiss’ high-end Otus line.
We at Accord Equips, are often asked why should someone buy or rent such expensive lenses? These lenses, though expensive, will add lots of flexibility to Mobile photographers and mobile filmmakers. Iphone has one of the best cameras and these lenses are the perfect partners for Iphone photography.

 

The Exo lenses screw onto a sturdy metal frame that is easily slip on and off your phone. It includes a 1/4-inch tripod mount socket and a slot on the top for attaching other accessories, such as an external flash etc. Mind you, the frame can be mounted only after stripping the Iphone cover.

 

 

 

Presently 3 lenses are available :      exo lens 1

The wide lens (0.6X)

The Exo wide angle gives you scene coverage equivalent to roughly 18mm. There’s the normal distortion you get around the edges of wide-angle lenses, but surprisingly little flare or fringing.

 

The Telephote lens (2X)

The telephoto lens is equaivalent to 56mm. Its great for portraits, something that the normal lens isn’t great for.

 

The Macro lens

And the macro lens works at various focus distances — unlike most phone macros — allowing for image coverage of 1 to 4 inches. It can be a little tricky at first to dial in the manual lens focus while the iPhone tries to auto focus, but it’s quick to master.

 

While the lenses are great, the screw mount can be awkward for quick swaps, the bracket mount blocks the camera’s flash and you’re bound to lose the expensive tiny back caps.

 

Are the Exo lenses worth their money? We felt that they will be a big boon for guerilla film makers, people web streaming using iphones etc. So yes, worth the money for serious photographers and film makers.

Sony E mount 85mm G master Block lens

Lens Sony 85mm Block
Mount E mount
F 1.4
Min focus distance 80cm
Blades 11

 

Overall

Sony E mount 85mm G master Block lens gives great sharpness and Bokeh & capture great details. So it’s a great lens.

 

Advantage of Sony E mount lens

-          Native AF system.

-          Benefits from all of Sony’s features including Eye AF

-          Works perfect with Sony A7s II, Sony A7R II, A7R, A7s etc.

 

AF / MF switch

-          AF/MF switches

-          Programmable Fn button (defaults to Focus Hold).

One can set the button to activate Eye AF for natural and easy access to the setting during use.

 

Operations

-          Rubberized focus ring helps you operate the lens smoothly

-          Improved focus-by-wire system helps these lenses to have a more natural feel does not seem to ramp up or down in speed depending on how fast you turn it.

 

Aperture ring

-          The integration of a physical aperture ring, allows to be clicked or de-clicked with a switch which makes it a great option for video shooters, as well as photographers.

 

Physical details

-          The small ridge on the bottom of the lens ensures that the lens’s aperture and focus rings are not lying directly on any surface when the camera is laid down.

 

Some Cons

The lens is slower than other native options due to the use of an older, and louder, Linear SSM system to move the large elements precisely, which could be changed by using the Direct Drive SSM available in many current models.

 

Chromatic Aberration at F1.4

There is a noticeable amount of chromatic aberration on high-contrast edges at f/1.4 which could of course be easily corrected in post

 

Tips : It gets better as you stop down, peaking at about f/4-5.6, where it will optimize the performance. Vignetting is also very well controlled and flare is nonexistent.

 

Focus Ring

There are still no witness markings on the lens and no hard end stops which makes them less appealing for use with follow and remote focus units.

They would work well with smaller handheld gimbals rather than larger Steadicams and gimbals
