A Technique for Macro Shooting with the Sony RX100 III Camera

I have received an interesting email message from Ron Pidot, a reader of my guide book for the Sony RX100 III camera, explaining how he used a novel approach to macro shooting with that model. Ron indicated that he did not mind sharing his technique with others, so I am posting the information here for use by anyone who would like to experiment with high-quality macro photography with this Sony model. It should work with other cameras in the RX100 family as well, though it has only been tested with the RX100 III. Here is what Ron explained:

“I thought you might be interested to know that I have been successful in shooting macro with the addition of a reversed Canon 50mm f/1.8 lens mounted on the 49mm adapter with a reversing ring instead of the usual close-up filters. I use manual focus with the aid of a focusing rail that adjusts front to back and left to right.  There is no discernible vignetting when zooming to 140mm. with the “clear image” zoom  setting. The  images are processed with the Photoshop Elements 11 Photomerge option using layer masks to achieve focus stacking. My subjects (small screws, dead houseflies and tiny shells) have ranged in size from 4mm-10mm in length. I lighted the subject with the YongNuo 560 IV strobe you mentioned, using the pop-up flash to trigger the slave.

Insects are not abundant now but I managed to capture an earwig about 25mm long and it filled the LCD screen. Perhaps your readers (if they don’t already know) might like to add this capability to other options for macro photography.”

Note About Problem with Ordering Sony RX100 IV Book

For a short time over the past day or two, there was a problem with the system for ordering the new guide book for the Sony RX100 IV camera. Because of a mistake in updating this website, customers who tried to purchase the bundle of the PDF and two other downloadable versions of the book were directed to the site for a particular seller that sells only one downloadable version of the book. The problem was fixed early on September 13 after a customer brought it to my attention. If you experienced this problem, please send a message to with the details, and we will get the proper files sent to you.

Please note, though, that I will be out of the office for a few days for a medical procedure starting on September 14, so it may take several days for you to receive a full response.

Nikon Issues Upgrade to Firmware Version 1.2 for Coolpix P900 Camera

Today I learned that Nikon has released an upgrade to version 1.2 of the firmware for the Coolpix P900 camera. This is not a major upgrade; according to Nikon, it fixes a couple of bugs concerning the ways the optional ML-L3 infrared remote control operates. I never experienced any problems with that remote, but it is probably a good idea to download and install the upgrade, if only to keep your camera’s operating system up to date.

Here is a link to the page with download instructions and the file to be downloaded: I installed the upgrade in just a few minutes, with no problems. Basically, you just have to download a file, copy it to a memory card that has been formatted in the P900, then turn on the camera with the card in it, go to the Firmware Version item on the Setup menu, and follow the instructions to complete the upgrade.

Problem with Cover of New Book About Nikon Coolpix P900

A sharp-eyed reader of Photographer’s Guide to the Nikon Coolpix P900 just pointed out to me that the cover photo on that book shows the Coolpix P610, an earlier model, and not the P900. How this very basic mistake happened I’m not sure, but it did, and I will take steps to fix it as soon as possible. Please be assured that the text of the book and the photographs inside the book all discuss and show the P900. But I will have the corrected version available in all formats as soon as possible, and anyone who purchased the version with the wrong illustration on the cover can contact me at and I will send you a corrected version as soon as it is available.

Comparison of Features of Leica D-Lux (Typ 109) and Panasonic Lumix DMC-LX100 Cameras

In January 2015 I published Photographer’s Guide to the Panasonic Lumix LX100,  a comprehensive guide book for that recent camera model. I am currently working on a similar guide for the Leica D-Lux (Typ 109), a model that is based on the LX100, but has some differences. In online discussions, I have often seen people debate whether there is much actual difference between the Leica and Panasonic versions of this camera. (There have been similar debates over the years about other pairings of Leica models with similar Panasonic versions, such as the Leica D-Lux 4 and the Panasonic LX3, the D-Lux 5 and the LX5, and others.)

As I worked closely with both cameras to write these guide books, I have developed a list of actual differences between the models, based on my experience in working with their features, menus, and controls. In the table below, I am producing that list, with a few caveats. First, I did not include minor differences, such as small variations in labeling or terminology. For example, Snapshot mode on the Leica is called Intelligent Auto mode on the Panasonic; the button for the electronic viewfinder, or live viewfinder, is labeled EVF on the Leica and LVF on the Panasonic; and the A button on the Leica is called the iA button on the Panasonic. Second, I did not engage in a comparison of image quality or internal image processing. My general impression is that there is no difference in how the images from the two cameras appear, when they are taken in the same conditions with the same settings, but I did not carry out experiments to test that impression. I am listing here only obvious, objectively verifiable differences between the two cameras. If anyone is aware of differences I have left out, or has other information that should be included here, please let me know.

Paperback Version of Panasonic Lumix LX100 Guide Book is Now on Sale at

As of today, Photographer’s Guide to the Panasonic Lumix LX100 is available for sale at in a paperback version for a list price of $29.95. This new book is 248 pages long and contains more than 350 color photographs that illustrate all menus, controls, and features of the LX100 camera. The book also includes samples of images taken by the LX100 using its various settings for creative photography.

The new book is produced in a different format from the previous guide books from White Knight Press. The LX100 guide is printed in a new size of 8.5 by 8.5 inches (216 by 216mm) as opposed to the earlier books, all of which are printed in a size of 8.5 by 5.5 inches (216 by 140mm). I am trying this new size as an experiment, because I believe it has some advantages, including putting more information and more images on each page, so the images can be closer to the text that discusses them. Also, I believe the book will be easier to work with, because it will lie flat and stay open more easily than the narrower size. I hope readers will provide feedback through this site with their reactions to the new shape of the paperback book. I am including some images here that show the actual book, to give you an idea of what it looks like.

Apple iPhone 6 Has NFC But Does Not (Yet) Support its Use for Connecting with Cameras

In my books about two of Sony’s compact cameras with Wi-Fi features, the DSC-RX100 II and the DSC-RX100 III, I discuss the fact that, with many Android smartphones and tablets, you can use those devices’ built-in NFC capability to establish a Wi-Fi connection with the Sony camera. NFC stands for near field communication, a feature involving the use of a radio antenna inside the device. When the camera and the phone or tablet are placed in physical contact with each other, their NFC antennas establish a Wi-Fi connection automatically so you can transfer images from the camera to the phone, and control the camera remotely using an app on the phone.

If the phone or tablet does not have NFC, then you have to establish the connection by going to the Settings app on the phone or tablet and selecting the Wi-Fi network that is generated by the Sony camera. The first time you do this, you also have to enter the password for the network. So, NFC cuts through one or two steps, and makes it considerably easier to get the camera connected with the phone or tablet over the Wi-Fi network.

In both of those books, Photographer’s Guide to the Sony DSC-RX100 II and Photographer’s Guide to the Sony DSC-RX100 III, I discuss the point that many Android devices include NFC capability, but iOS devices such as the iPhone and iPad do not.

With the recent release of the iPhone 6 and 6 Plus, both of which were said to include NFC features, I was hopeful that the new iPhone models would be able to use NFC to connect directly to these two cameras (and other cameras that have similar features). But no such luck. It has been disclosed that, at least for the near future, Apple is limiting the use of NFC to its new Apple Pay service, which will let you pay for purchases using the iPhone by pointing it at a device in a store or business that has the necessary equipment. For the time being, Apple is not permitting the NFC capability to be used for other purposes, such as communicating with camera apps.  Here is a link to an article that explains the situation.

I will continue to monitor developments in this area, and, when and if Apple permits the iPhone’s NFC capability to be used for connecting to cameras, I will post an update on this site.
