PSA: Apple warns that high-powered motorcycles can damage autofocus, image stabilization in iPhones

Apple has published a new support document on its website warning users that cameras on their iPhone devices can be damaged when attached to high-powered motorcycles due to the ‘high amplitude vibrations’ of their engines.

In the document, Apple specifically points to the optical image stabilization (OIS) and closed-loop autofocus (AF) technologies inside its latest iPhone device and notes both of these are susceptible to performance degradation over time when exposed to the ‘extended high-amplitude vibrations,’ such as those put through the device when it’s attached, via a mount, to a motorcycle. Specifically, Apple notes the OIS systems inside the iPhone 6 Plus and later and the AF systems in the iPhone XS and later are the modules affected by these issues.

‘High-power or high-volume motorcycle engines generate intense high-amplitude vibrations, which are transmitted through the chassis and handlebars,’ says Apple. ‘It is not recommended to attach your iPhone to motorcycles with high-power or high-volume engines due to the amplitude of the vibration in certain frequency ranges that they generate.’

Even smaller motorized vehicles, ‘such as mopeds and scooters,’ can lead to problems, despite ‘comparatively lower-amplitude vibrations,’ according to Apple. To lessen the risk of damage on these devices, Apple suggests using a vibration dampening mount and ‘avoid regular use for prolonged periods.’

A nature photography tour of Madagascar, Part 3: Kirindy Forest


In the last two articles in this series, I wrote about my visits to Andasibe National Park, where I photographed lemurs and chameleons, and Tsingy Rouge National Park, where I saw beautiful erosion-formed formations. This time, I’d like to write about my visit to Kirindy Forest.

A Verreaux’s Sifaka, my favorite lemur species in Kirindy, feeding in a tree. The eyes on some of these lemur species are incredible.

Kirindy Forest (or Kirindy Private Reserve) is a private nature reserve located in the west of Madagascar. The forest is home to a wide variety of animals, from many species of lemurs to fossas (a very weird-looking predator) to geckos and chameleons. Numerous species of plants and trees are also found in the region, the most famous and iconic of which is the baobab tree.

From a photographic point of view, Kirindy is nothing less than a paradise and was one of my favorite locations on my month-long Madagascar trip. The wildlife is surprisingly easy to find and photograph (with many highly skilled and cheerful guides available on the premises), the baobabs are easy to get to, and there are comfortable accommodation options close by. The only bad thing is the Wi-Fi connection.

Lemurs are one family of primates Kirindy has no shortage of. There are no less than eight lemur species here, from the tiny Madame Berthe’s Mouse Lemur (the smallest primate in the world, weighing 30 grams) to red-fronted lemurs, sportive lemurs and sifakas. I photographed all of Kirindy’s diurnal species in three days, which shows how easy they are to find with a good guide. As to being easy to photograph, that’s a different story.

The easiest species to find in Kirindy is the red-fronted lemur. They are small and relatively common, so one could say they’re also the least exciting of the local lemur species, but I found them to be very cute and expressive subjects.

Unfortunately due to massive deforestation and climate change, Madagascar’s lemurs are losing their ability to migrate and access water. Authorities are trying to help them by giving them water. The red-fronted lemurs are, therefore, much less averse to getting close to humans. I really hope this doesn’t hurt them in the long run.

A red-fronted lemur is feeding in a tree. Its interaction with its environment is what makes this image. These animals are cathemeral, meaning that they are active during the day and at night, especially during the full moon.

The interestingly named sportive lemurs appear not to be sportive at all. Most of the time, they rest in the trees to digest the plants they have eaten. But during the mating season, male sportive lemurs have been observed to box with each other, which gave them their unusual name.

This sportive lemur looked like it had one too many drinks the previous night!

The crown jewel of Kirindy’s wildlife selection (in my opinion) is the Verreaux’s sifaka, a beautiful, medium-sized lemur. Its thick and silky fur is mostly white, other than dark brown patches on the top of the head, face and arms. Like all sifakas, it has a long tail that it uses as a balance when leaping from tree to tree, where they are capable of making remarkable leaps. Distances of 9–10m (30ft) are not uncommon.

As a rule, the better composed the jumping shots I got, the worse the sharpness was on them. These guys are notoriously hard to catch when jumping. Here’s an effort, with the sifaka showing its trademark Superman-style jump.

Unfortunately, sifakas are very hard to photograph. They tend to stay very high up in the trees, which keeps them both far away and at awkward angles. This forces the photographer to use longer lenses, which becomes surprisingly tiresome when hand-holding the camera. I wanted to shoot at eye level but ended up shooting upward the vast majority of the time. They also just love hopping from tree to tree exactly when a photographer has finally found a good composition.

This sifaka looked like something out of a Dr. Seuss book. Note the shooting angle is less than optimal here, due to the height of the tree it was sitting on.

As beautiful as they are shy. A lucky eye-level shot.

My visit to Madagascar was during baby season for lemurs, which was wonderful. I ended up seeing many species carrying very young and impossibly cute baby lemurs, and the sifakas were no different.

Again, the challenge was the distance and their tendency to move around all the time, probably even more so when carrying babies. Unfortunately, about 30% of infants are lost to predators like the fossa, a cat-like mammal, and a smaller number to raptors such as the Madagascar harrier-hawk.

For the first 6-8 weeks, the infant clings to the mother’s stomach, but for the following 19 weeks, it clings to her back. During my trip, I saw infants up to 8 weeks old. I guess the signature eyes are there from birth!

I’m not much of a bird photographer, but several beautiful owl species are in Kirindy, and they were relatively easy to find.

Finally, the Kirindy area was once home to a huge forest of baobabs. Not many remain, but those that are still there are huge and impressive. It was fun photographing a group of baobabs in the late afternoon and early evening, under direct light and during post-sunset glow.

The more baobabs close together in one location, the harder they are to compose, but if you manage to combine multiple elements into one shot in a satisfying way, then perhaps you’ve achieved something.

Here, I used the gaps between the foreground trees to frame the background trees.

I highly recommend visiting Kirindy Forest if you’re interested in Madagascar’s wildlife. The concentration of fascinating species and relaxed atmosphere are unmatched.

In the next article in this series, I will write about my journey from Tsingy De Bemaraha National Park to Isalo.

DPReview Rewind: the birth of the Canon EOS D30, its first ‘home grown’ DSLR

DPReview Rewind: the birth of the Canon EOS D30, its first ‘home grown’ DSLR


In the early days of digital, cameras were big, bulky, expensive and mostly out of reach for people unwilling to shell out professional-level MSRPs. Then came the Canon EOS D30, a landmark camera that introduced a slew of film photographers to digital, inspiring photojournalists to give up high-end film cameras and a new generation of wedding photographers, portraits and landscape artists to dip into the DSLR pool.

At $3000, it was not cheap, but it was within reach of a new category of camera buyer, the ‘prosumer.’

During our 25th anniversary year, we’re looking back at some of the milestones in camera history. On this day in history, on May 17, way back in the year 2000, the D30 was announced as Canon’s first built-from-the-ground-up in-house DSLR. Up to this point, Canon’s DSLRs (the EOS D2000 and EOS D6000) were joint ventures with Kodak. These cameras married Kokak internals with Canon bodies.

With the new camera, Canon was doing it all themselves, including designing a new body, its own sensors and processors and the introduction of its own RAW and JPEG engines. It would also become the first DSLR with an APS-C format CMOS sensor, a blistering 3.25MP beast capable of 3 RAW image bursts (or 9 Fine JPEG) and a full day of shooting on a single charge. It was pretty cutting-edge for the time.

The camera would arrive on store shelves in time for the holidays. In our review, dated Oct 10, 2000, we noted the monumental task that Canon had taken on. They had not only taken on building a camera on their own and decided to use a relatively new high-resolution CMOS sensor at a time when CMOS struggled with high megapixel builds, but they also had to know consumers would be comparing their camera to the previously announced, although not yet released, Nikon D1.

But Canon had pulled it off, and we were impressed, writing: “Canon’s engineers, designers and developers haven’t let them down, the D30 WILL go down in history books as a very important camera, breaking a price barrier and opening up the digital SLR market (more so than Fujifilm’s S1 Pro) to a new wave of users, both new and old. From the minute you pick up the D30 … you get a feeling of quality you weren’t expecting.”
