Look what you can do with a hacked Canon A650 & Helios 44M-5 lens

Hacked Canon A650 with Helios 44M-5 lens

These are the hacks I love most. Alexey Kljatov took a Canon A650 (2007) and did his own thing mounting a Helios 44M-5 58mm f/2 lens on the camera. To make this hack really fit for macro photography, the lens was attached backwards.

The hack appears to be made quickly and doesn’t look neat. However, it produces amazing images like the snowflake photo below. That’s the real hacker spirit: take gear, modify it following an idea, realise something awesome.

Kudos Alexey Kljatov for the cool hack! Be sure to have a look at his website for more amazing macro shots done with the hacked Canon A650, and to learn the how to of his macro setup plus a ton of information about macro photography.

Canon EF 400mm f/2.8L IS II lenses used to discover a new “Dark Galaxy” with Dragonfly Telephoto Array

Canon EF 400mm F/2.8L IS II Lenses Used To Discover A New “Dark Galaxy” With Dragonfly Telephoto Array

Do you remember the Dragonfly Telephoto Array developed by the University of Toronto’s Dunlap Institute for Astronomy and Astrophysics? Well, there are some news.

First things first. What is the Dragonfly Telephoto Array?

Dragonfly is an innovative, multi-lens array designed for ultra-low surface brightness astronomy at visible wavelengths. Commissioned in 2013 with only three lenses, the array is growing in size and proving capable of detecting extremely faint, complex structure around galaxies. The most recent upgrade—completed in 2016—saw Dragonfly grow to 48 lenses in two clusters.

Last time I reported about Dragonfly it had 10 lenses mounted, now the lenses are 48. To build the Dragonfly, scientists used Canon EF 400mm f/2.8L IS II lenses, because of “unprecedented nano-fabricated coatings with sub-wavelength structure on optical glasses“. I guess the lenses were modified according to the scientists’ needs.

Next, what is the Dragonfly Telephoto Array good for?

Dragonfly is designed to reveal the faint structure [of the universe] by greatly reducing scattered light and internal reflections within its optics. It achieves this using commercially available Canon 400mm lenses with unprecedented nano-fabricated coatings with sub-wavelength structure on optical glasses.

Also, Dragonfly images a galaxy through multiple lenses simultaneously—akin to a dragonfly’s compound eye—enabling further removal of unwanted light. The result is an image in which extremely faint galaxy structure is visible.

Well, scientists discovered a previously unknown Dark Galaxy by using the Dragonfly Telephoto Array. The galaxy was named after the array. As The Atlantic reports:

Dragonfly 44 is a dim galaxy, with one star for every hundred in our Milky Way. But it spans roughly as much space as the Milky Way. In addition, it’s heavy enough to rival our own galaxy in mass, according to results published in the Astrophysical Journal Letters at the end of August. That odd combination is crucial: Dragonfly 44 is so dark, so fluffy, and so heavy that some astronomers believe it will either force a revision of our theories of galaxy formation or help us understand the properties of dark matter, the mysterious stuff that interacts with normal matter via gravity and not much else.

The discovery was made by astronomers Pieter van Dokkum of Yale University and Roberto Abraham of the University of Toronto. They did not use Canon sensors, tough. The lenses are mounted on SBIG STF-8300M CCD cameras. The array began imaging targets in 2013 from its home at the New Mexico Skies hosting facility.

How to transform a inexpensive DIY keychain game kit in a Canon timelapse remote

capture

Cool hack by Ilya Titov: a keychain sized gadget that allows you to set a timelapse triggering scheme for your Canon DSLR.

All you need is a small game kit called Attiny Arcade, a small IR LED which will be used to send commands to the camera, and the necessay code to operate the remote. The software is open source and can be downloaded here.

The project doesn’t seem difficult to realise.

How to make stereoscopic images with Canon EOS 5D Mark IV’s Dual Pixel RAW

How To Make Stereoscopic Images With Canon EOS 5D Mark IV’s Dual Pixel RAW

A user of DPReview’s forum discovered that you can produce stereoscopic images with Dual Pixel RAW files of the new Canon EOS 5D Mark IV.

I don’t think this was planned by Canon when they implemented Dual Pixel RAW. On the other hand, it’s a pretty good example of the potential of this technology. I am sure we will see more new applications of Dual Pixel RAW. As soon as the EOS 5D Mark IV starts to be widely used, such discoveries will pop up.

You can learn about making stereoscopic images with Dual Pixel RAW files in this thread. CR2 files are available for download so you can try it for yourself. Another discussion thread about stereoscopic images made with Dual Pixel RAW files is here.

If you want to learn more about Dual Pixel RAW I recommend this article by Canon DLC.

Canon publishes free EOS AF Microadjustment Guidebook

CDLC

Canon Digital Learning Center published the Canon EOS AF Microadjustment Guidebook, and made it available for free. You can download the Canon EOS AF Microadjustment Guidebook it here. The guidebook comes as PDF file or mobile version.

AF Microadjustment has been a feature in mid-range and high-end Canon EOS D-SLRs for some time now. But there have been questions, and more than a little confusion, about the best process to test and perform these adjustments.

Canon Inc. engineers have provided a guidebook that shows the steps a typical camera owner can perform to indeed test his or her lenses, and determine whether adjustment is needed.  And, it describes how to carry out the adjustment procedure.  This guidebook applies to any Canon EOS digital SLR with built-in AF Microadjustment, and applies to all Canon EF and EF-S lenses.  We hope it clarifies some points for our customers, and shows that the Microadjustment procedure doesn’t need to be a long, technical process.

The guide applies to all Canon DSLRs featuring AF microadjustment.
