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

You dropped your Dslr camera in the water what to do now ?

you-dropped-your-dslr-camera-in-water-what-to-do-now
Last week we have a nice time with my family in Siofok which is the most popular place next to Lake Balaton for a summer holiday. I love to take pictures when I am in the water.

I was asked to bring something for my daughter while I need to walk a bit. After backwards I see a concrete deck which leads to a shallow 1′(30cm) deep water. Without thinking I put my leg on the deck, than I realized that it is very slippery, because it was heavily covered with green material from the water. While slipping, I try to keep on board with little ski and other sports experience, but at the end of the deck I literally fly :-) into the water, with my Nikon D7000 in my hand.

My wife said funny I do waterski or what she didn’t understand. When I stood on my feet again, look at my camera and realized it was underwater.

You dropped your Dslr camera in the water what to do now ?

This list is not obligatory, do as you want, just an idea, what I think.

0. Pour water out as quick as you can

This step is the most obvious, turn, shake a camera a little bit to get rid of most of the water. Do not spend much time do the next step instead. In fact the 1. step can be really the first, but when you get your camera out of the water obviously you want to remove all water very quickly.

1. Turn off – Remove battery

In my study in the Technical University says this, water leads electricity. If water goes to unwanted areas in your camera it is not a good thing for the camera’s circuitry.

Advanced cameras has a continuous sleeping mode I think, turning off perhaps not enough to switch off electricity totally, remove battery seems more sure for me.

2. You can spend little more time to remove additional water

You can exchange this step with the next if you want depend on importance / preference. To do this I opened all slots on my camera and try to hold it in a dry place. I first I hold against bright sunlight, but perhaps not always the best as sensors not really like overheating.

3. Remove memory card if you want to save the pics you made

If you have very expensive or precious pictures or videos on your camera, this can be the first step even.
Memory cards are usually in safer position than your camera inside, if the memory card slot has a cover, it usually protects the cards.

4. Remove lens if not water sealed

It was funny this was the first time I realized than my Nikkor 16-85mm has water sealing around the mount. Very useful feature I would say, as not many water was in my Dslr camera inside. In my experience the lens as not vulnerable for water, but it can be nasty if it gets inside. Drying here also needed.

5. Put it in a dry place and wait several days depend on the dryness

I put my camera at the top of the wardrobe for 3 days to get dry.

There are tricks to put rice in the camera to absorb water if you can.


What happened with my camera ?

Well after I removed the water, hold it under direct sunlight about 20-30 minutes, At first seem the camera is still working but later get an Err note which stays there even 2 days after the accident.

After at the back LCD has different colors, some parts has white colors others are dark black (looks burned or something) and rainbow colors in between. The situation looks not really promising at all. After I see the Err note I immediately remove the battery (it was needed to do much earlier). I though some reparation is need or other option I will never used the camera again.

After three days the Err massage disappeared and now seems working without any problem. It may not be for every case, I camera had very little water inside, when I removed the lens actually was surprised how little water is inside the camera. Different cameras has different water sealing. I think learn from the steps above if you never experience such a thing and perhaps you will be lucky as well.

Avoid such slippery places if you can :-)

Tamron 150-600 G2

Tamron 150 600 G2

Tamron raise the bar again. When Tamron released the first generation 150-600mm lens in 2013 it was a massive success. Even Tamron was surprised the demand for such a lens, one needed to wait months to get a copy. No such lens was at a comparable price on the market. Focal length of 600mm with very good optical performance for only 1069 USD (if I remember well). A Powerful telephoto not just for the richest.

After Sigma quickly try to save the market with 2 versions of their 150-600mm (Sports and contemporary), and Nikon also got into the business with a 200-500mm, and there were rumors about a new Canon 200-600mm. (Not yet released, wouldn’t be surprised to see a new 10K USD lens)

Tamron 150-600 G2

I like what Tamron did the most, real quality for an affordable price.

After releasing the two 150-600 Sigmas reviewers questioned that the Tamron is not tack sharp at 600mm wide open, although before there were no such or similar lenses for decades.

Now comes with the G2 (second generation) version with:

– Improved optics
– Improved autofocus
– 2.2mm minimum focusing distance (86,6 in.) very nice for macro
– Zoom lock at any position
– two teleconverters (1.4x, 2x specially designed for this lens up to 1200mm
– Improved built
– Higher price (1399 USD)

With the improved price the new Tamron competes with the Sigma 150 600 Sports and the Nikon 200-500 I think with a significantly cheaper, more affordable price, or at least beat the Contemporary 150-600 Sigma.

Tamron 150-600 G2 specs Model A022
Mounts: Canon EF, Nikon F, Sony
Lens construction: 3 LD elements (21 elements / 13 groups)
Filter size: 95mm
Lens weight: 2kg, the Canon version little more, the Nikon is little less
Flex Zoom lock: yes, can be fixed at any position
Full time manual focus override: yes
No of aperture blades: 9
Length:
260.2mm (10.2 in) Canon
257.7mm (10.1 in) Nikon
Vibration compensation: yes
Tamron 150-600 G2 Flex zoom lock mechanism

This feauture sound really cool and very useful, in order to prevent zoom creeping. Usually we want to use the longest zoom setting or we can choose our favoured combination of focal length and aperture. Shorter focal length usually has brighter aperture values. With the new zoom mechanism we can easily fix the zoom at any position simply by pulling the lens.

Sunset from the water

Sunset from the water
Click on the pics to see in proper size.

How to make such a picture ? Go into the water before sunset and try to capture the line where the sun reflect on the water from a low perspective of several inches / centimeters. You can make it easier from a shallow lake than a deep one, especially if the water is cold.

You can play with many things like you hold the camera in normal or portrait position, you can choose what you want in your composition, the angle between the camera and the lens, the focusing distance, the depth of field, if you use longer focal lengths you can blur the background more.

You can also play with exposure, to make the pics darker or lighter. My Nikon camera calculate the light as the image is darker, but with exposure compensation it is easy to make it lighter, this way the people in the background will be more visible.

You can decide as well you want a full sun, half sun or exclude the sun from the frame.

You can also play the angle how to hold the camera, downwards, upwards or in between.

Here in this shot I used wide angle and small aperture for more depth of field and try to focus relatively closely.
After you can crop the pics anywhere you want.

Black and white experiments

In some cases when we are amid lot of different colors (for example in a kids playing room) we want to get rid of them. Some cases the too many colors can be disturbing, and can attract our attention away from the main theme. We switch to black and white and we have a much simpler image. We can create black and white photographs multiple ways, either desaturate the colored photographs or simply use BW picture style if we have it in our camera settings. Lately I chosed the BW camera setting on my Nikon d7000 as the ones I desaturated from colored ones doesn’t look like I would like them to look like. At first BW photograps can look awkward, but if we know what we want, we can get very happy with these photographs. Some cases a colored photo looks much better, depend on our preference.

Black and white experiments
You can click on the pictures to see them in higher resolution, which I prefer over small web size. I like the above photo, not because it is a brilliant view, but looks like the time has stopped for a moment, like a memory. Perhaps the background music can help as well, which I hear. The photo was made next to River Tisza in Hungary, which is the second biggest river in Hungary, where you can find this kind of place. Not many places like that without lighting, pavement and artificial surroundings. This beach is totally natural at this state, nothing just nature, huge trees, not even a stairs, you can reach the shore from steps which is made by dug the natural soil. Not many places like this in the World today, apart from the abandoned areas.

Black and white experiments 2
The black and white photographs are much simpler and the shapes and forms, and light level differences are more obvious. Interestingly Ansel Adams used BW for their landscapes, although he could also would have used colored photographs as well.

Retro look / feel

In many cases black and white photographs can look retro as it can resemble the film photographs. What do you think about the photograph below ? When it was taken ? (2016 august)
Black and white experiments 3

Portraits

The easy win situation in Black and white is portraits. Either a wedding portrait or other, we can create very nice photographs without strong efforts.

Some points for experimentation

– Strong lights
– Shadows (for example a tunnel)
– Reflection
– Portraits
– Out of focus shots
– Retro objects combined with oof
– Clouds
– Blacks
– Whites

About Dzoptics

Perhaps few people heard about DZopics yet. The Shenzhen Donzheng co is in the optical industry for more than 10 years. They involved in multiple fields of optics like medical, military, lighting, security, laser and many more.

They prouduce scan lenses, large format lenses, CCTV lenses, tele centric lenses, focusing rings and adapters as well.

Seems the unique, bright 35mm is their first photographic lens though.

The lens has a stepless aperture, which can be regulated by a switch.

How Watkins saved Yosemite ?

how watkins saved yosemite
Charleton E Watkins was an early landscape photographer in the US. He visited the Californian area in 1861 with his middle format film camera. He took high resolution images on huge slides.

The pictures somehow found Abraham Lincoln the president of the United States at that time, who liked the pictures so much that he gave the area a protection by law. Later the Yosemite became the second National Park in the US in 1890.

This was the first case when photography changed the history according to Matthew Butson the Vice president the Archives of Getty images.

New Zenith lenses

zenith lenses coming
On the picture is a very old Zenith camera

Which Zenith lenses are coming ?

Seems Zenit comes back with three lenses, the Zenith 85mm f/1.2 the Zenith 50mm f/1.2 and the Zenith 50mm f/0.95 lenses. Zenith had some very popular lenses like the Jupiter 135mm f/2.8 is still used in Hungary by some or the Zenitar 16mm fisheye lens which was available in the US as well, and had a good reputation.

New Zenitar 50/0.95

This lens is designed for Sony FE mount cameras. Has many aperture blades, 14 if I remember well, in two different depths. The lens has a 72mm filter thread, the lens construction is 9 elements in 8 groups.

New Zenitar 50/1.2

This lens is designed for Full frame cameras. It will be available for both Canon EF and Nikon F mounts. Perhaps this will be the first lens released sometime this year. Currently it is a massive 1200g lens, Zenith is working on to make it smaller.

New Zenitar 85/1.2

It is also designed for Full frame cameras, with a design of 9 elements in 7 groups, has a 82mm filter thread, and metal mount. It will be available for both Canon EF and Nikon F mounts.

Price and release date is not yet known of these lenses (some projected for 2017), but according to some information the lenses will not be more expensive than 600 USD.

If you good at Russian language you can read more about these lenses here at Denis Gavrilov website
