New Sigma Art lenses coming. At this time we can expect 4 new lenses, some of them are unique in the market. Nowadays Sigma really rocking, with lenses like the Sigma 18-35mm f/1.8 Art, Sigma 50mm f/1.4 Art , or the Sigma 35mm f/1.4 Art series lenses.

The standard workhorse lens of the wedding photographers.

Sigma 135mm f/1.8

King of bokeh type of lens with a unique f/1.8 aperture.

Canon 77d release date

canon-77d-release-date

Canon 77d release date is expected in April 2017. At the moment it looks like a 200 USD cheaper 80d, if the sensor is the same. It looks has anything Canon has to offer, apart from 4K or other gimmicks.
The new Canon dslr camera coming between the Canon 80d and the Canon 770d with a 24,2 megapixel CMOS sensor. This camera starts a product line on his own, which is in the serious amateur consumer-prosumer segment. The camera has 45 all cross type focus points and a Dual pixel af system.

It will have newer processor (DIGIC 7), has lower burst speed (6 fps), higher native ISO range (100 – 25,600) than the Canon EOS 80d. The LCD monitor is articulated touchscreen. The camera has a Dual-pixel autofocus, but no phase detect focus (Meaning non Canon lenses won’t af in live view mode I guess). The viewfinder coverage is lower (95 vs 100%) than the coverage of the 80d. The price of the new 77d is 200 USD cheaper, than the price of the 80d.

Canon 77d specs
Pixel count: 24,2 effective / 25,8 Megapixel
Exposure compensation: +-5 EV, +-3 EV in AEB
Highest res: 6000×4000

Battery life: 820 shots using the viewfinder
Movie recording time:


The question is whether the new sensor used in the Canon 80d is in the camera with the wider dynamic range or the older one in the 760d (13,2 vs 12 EV), or something in between. Between the two sensor there is a significant difference in high ISO performance (1135 vs 915) and color depth (23,6 vs 22,6 bits) as well.

Compare to the 80d apart from the sensor are the following: less viewfinder coverage (95 vs 100%), lower burst rate (6/7 fps), lower max shooting speed (1/4000s vs 1/8000s) but has wider native iso range, newer image processor (Digic 7 vs 6). For me any of these are not seem a deal breaker, if the sensor is the same.

Canon M6 release date

The camera will be available from April 2017.

The initial price of the new Canon EOS M6 is 899,99 USD.

Sigma 85mm 1.4 Art release date price specs

sigma-85mm-1-4-art-release-date

Seems the long awaited Sigma 85mm 1.4 Art portrait lens is finally coming. This lens was expected when the Sigma 50-100mm f/1.8 Art lens was released. This kins of a lens is a workhorse for the professional portrait photographer. For 1200 USD it is not really cheap, but much more affordable than the competition (Nikon 85mm 1.4 and the Canon 85mm 1.2 version II lenses). The wide f/1.4 aperture helps to create pleasing buttery creamed background for portrait photography. I think this lens is extremely sharp if it follows the line of the Sigma 18-35mm f/1.8 Art, Sigma 35mm f/1.4 Art, and the Sigma 50-100mm f/1.8 lenses. Regarding the competition it is cheaper by 400 USD than the Nikon version, and 600 USD than the Canon version (the 1.2 though), which makes the lens quite attractive.

Sigma 85mm 1.4 Art specs

Filter size: 86mm
Lens elements / groups: 14/12 not the simplest design
Special lens elements: 2 SLD and 1 asperical lens element
Lens weight: not specified by the manufacturer, means it is a heavy beast or put it another way the optical quality is the most important here
Minimum focusing distance: 85cm
Max. reproducing ratio: 1:8.5
Dimensions: 3.73 x 4.97″ (94.7 x 126.2 mm)
Angle of view: 28.6º
Aperture range: f/1.4 – 1/16
No. of aperture blades: 9
Compatibility: Full frame
The lens is compatible with the Sigma’s USB dock and the MC11 lens converter.

Sigma 85mm 1.4 Art price

The price of the new Art series lens is 1199 USD. (January 2017)

Sigma 85mm 1.4 Art release data

The lens can be purchased from 2017. It is already available, but seems it is back ordered.

Sigma 85mm 1.4 Art MTF curves

Below you can check the MTF curves for the new lens.
sigma-85mm-1-4-art-mtf-chart
The upper line is the contrast the below line shows resolution (detail).
The left part of the chart shows the center of the lens, the right part is the extreme corners.
The ideal MTF would be a horizontal line as close to 1 as possible.

Actually if we use this lens for portraits the corners are not so relevant, but I am sure everyone prefers dead sharp corners as well, if for example we use the lens for landscapes occasionally.

Monitor cleaning spray

monitor-cleaning-spray
I sit in front of the computer for years, and if I wanted to clean it (with a wet cloth normally), usually I was not really successful. I don’t know how but got this monitor cleaning spray (see above). It does the job perfectly. I can recommend it wholeheartedly. Just makes the monitor perfectly clean. I don’t see any reviews about monitor cleaning equipments or products just got this.

Perhaps it is not a big relevation for most people, but perhaps there are some out there who like me. If you have some tips/experience in this matter, you can share it in the comments.

Sigma 85mm f1.4 Art

sigma-85mm-f1-4-art
The long awaited Sigma 85mm 1.4 Art is almost here. The lens accepts 86mm filters, and bigger and heavier than the competition. It comes after the very popular, high performance Sigma 35mm f/1.4 Art or the Sigma 18-35mm f/1.8 Art lenses.

Why is this lens is so awaited ? Because it is the classical short telephoto portrait focal length, when we can create very nice creamy background blur. Most professional photographers are portrait or wedding photographer, and this lens is one of their workhorse lenses (the others can be a 24-70 or 70-200mm). Before this lens Sigma released the also very interesting Sigma 50-100mm f/1.8 Art lens which can be also very interesting for portrait photographers.

Sigma 85mm f1.4 Art official name

The official name of the lens is Sigma 85mm f1.4 DG HSM Art

HSM – Hypersonic focusing motor
Art – the new line of Sigma lenses, usually with bright aperture

Sigma 85mm f1.4 Art specification

Mounts: Sigma, Canon, Nikon
Filter size: 86mm
Weight: Not specified, seems this a weak point, I guess around 0.8kg or little more. The Nikon is 591g, the Canon 85mm 1.2 II is 1025g for reference.
Lens elements: 14 elements in 12 groups
Max magnification: 1:8,5
Min. focusing distance: 85cm / 33″

What’s new here

The Sigma Art line lenses has great build quality, with high unique optical performance usually, as we seen this in several such lenses in the past. The optical design as you can see below is quite complex, with many lens elements. It is designed and tested for the new, high megapixel cameras.

The forest man of India

the-forest-man-of-india
Click on the next image to see the video. This is just a jpg with no link.
I like trees very much, and I plant some trees as well single handedly. But the man in this story exceeds any imagination. He’s name is Jadav Payeng. See the story in more detail in the following video.

Jadav lives in the island of Majuli which once was covered with thick vegetation. Unfortunately the area become flat later, without trees or other vegetation. Jadav single-handedly built 1200 hectare forest himself, 37 years ago. He spent his last 30 years of life to plant this forest, which is now a home of 5 Tigers, included in the migratory route of Elephants and home of many creatures.

Gopro 5

gopro-hero-5

Gopro 5 Black edition

Here you have it the best Gopro ever as they advertising it, 4K video at 30fps, 12 Mp stills photos even in Raw format for the Black edition. This version also has a GPS and a 2 inch Touchscreen. The camera can record HD videos at 120 frames per second rate and 1440p videos at 60 frames per second rate.

30 frames per second time lapse videos are also possible to record with the new camera. There is Wifi, and Bluetooth as well with automatic upload to cloud. Image stabilizer, wind noise reduction and voice control is also built-in the camera. The camera is waterproof up to 10m depth without housing.

Gopro 5 Session

gopro-hero-5-sessionThere are two versions, the cheaper Hero 5 session version is smaller which can shot 10 MP photos, but lacks GPS and the monitor completely.

This cheaper camera has an image stabilizer as well, for steadier, sharper clips, voice control and wind noise reduction system as well. The camera is waterproof without housing until 10m depth. It can record 10MP timelapse videos at 30 frames per second rate.

This is a big improvement compare to the earlier versions as I see, the image stabilizer only makes a huge difference.

Seems no white edition at this time, which was the most popular at the 4 series cameras.

Gopro Karma

Along with the new Gopro 5 cameras, there is a new Drone as well, called Gopro Karma.

The cameras will be available from October 2016 (UK).

The initial price will be 430/330/230 Pounds for the different models. The cheapest is the Gopro Session without 5 in the name.

Clean up the Oceans !

Clean up the Oceans !
There are many news in this world and let’s face it most of them is not positive. Climate change, war, who stole what, etc. This news is very positive though.

The founder

A 22 years old Dutch young men called Boyan Slat wants to clean up the Oceans.
We know the problem there are huge quantity plastic in the Ocean. Boyan faced the situation when he was 16 years old on a family holiday. There were more plastic in the Ocean than fish.
Every year mankind put so much plastic in the Ocean which is like a football field full with plastic and 18 miles high (8 million tons). And this quantity can be duplicated in the future.

Half of this quantity is beleived to be found in US West Coast in a size of Texas state.

The idea

clean-up-the-oceans
Perhaps at first the whole thing looks unrealistic or even funny but there is a plan as well not just a good intention. The idea is a long floating structure which collect the plastic with the power of the Oceans streams. This is little similar when they collect oil from the Ocean. For the above mentioned huge area a 100km structure is needed, and in 10 years the plastic can be removed or at least closed inside the structure.

The steps

Already many people involved in the ambitious project.
1. Investigation
2. Testing the structure at the North sea, the question how durable is the floating structure, is it strong enough to survive years in the Ocean while collecting garbage ?
3. New test near Japan
4. Clean the big waste in US West coast
