Canon Announced Digital Photo Professional Express for Apple iPad






Canon has released Digital Photo Professional Express for Apple's iPad. The software can import and process .CR3 files on any iPad running the iOS operating system. You can download DPP Express at the App Store. It is currently not available for devices running the Andriod system.

“For portable and wireless digital photography workflows, Canon’s Digital Photo Professional Express (DPP Express) brings the powerful features of Canon’s DPP software to your compatible iPad. Working with Canon’s Camera Connect app*, DPP Express streamlines the processing of JPEGs and .CR3 RAW files with an intuitive and powerful interface. View images and adjust settings right on your mobile device, and save files to the cloud, a computer or your camera. With DPP Express, it’s incredibly easy to maintain a wireless RAW workflow on the go."

"To create and compare different versions of the same image, DPP Express enables Multiple Editing Histories. Helpful in differentiating and comparing effects or setting changes on the same image, this feature creates up to four editing histories to view and save. To apply the same set of corrections to different photographs, Edit Histories can even be copied and pasted among images using the DPP Express Copy and Paste adjustment functions.”

Canon EF 300mm f/2.8L IS III and EF 500mm f/4L IS III Coming Mid Year 2019





Canon recently announced the EF 400mm f/2.8L IS III and EF 600mm f/4L IS III on September 5, 2018. The new super telephoto lenses received a weight reduction of about 25% and 20% respectively.

Since the EF 300mm f/2.8L IS II and EF 500mm f/4L IS II should be announced by mid 2019. Do not expect the same level of weight reduction, as those two lenses are significantly lighter than their 400mm and 600mm counterparts to begin with. I expect a weight reduction of about 1/3 to a little more than 2/3 of a pound, respectively.

The one lens I am most interested to purchase is the EF 600mm f/4 DO BR. Canon showcased it during the Canon Expo in September of 2015 in New York City. This will be the ideal Super Telephoto lens for wildlife photography for me. My current EF 400mm f/4 DO IS II can be a bit short on occasion.

Canon EOS-R Flagship Camera Coming In 2019?




Canon announced the EOS R system featuring the newly designed RF mount on September 5, 2018. You can download the whitepaper on this new body here. I was invited by Canon to a hands-on demonstration of the production camera on September 9.

My readers know me as The Wildlife Ho-tographer. I have been using Canon gear for over 30 years. You can follow my travels on Facebook and Twitter, see my equipment bag and works on MichaelDanielHo.com

As you know Wildlife Photography is very different from other forms of photography. It is tough enough to find and keep up with the wildlife. There is no time to fumble around with camera buttons while trying to keep one's eyes on the action once it is located.

The EOS-R's button layout and functionalities are so different from my bread and butter cameras (EOS-1D X Mark II, EOS-7D Mark II, EOS-5Ds, EOS-5D Mark IV) they require a major effort to familiarize and master. The payoff is not worth the effort for me. I have expressed my feelings on how Canon can make a successful full frame mirrorless camera suitable for professional wildlife and sports photographers.

Sadly, the EOS-R does not do fit any of my requirements except the feel and EVF of the camera is good. As expected, the pro model of the EOS-R will be announced some time in the first half of 2019 to compete with the Sony A9, Nikon Z7, Panasonic S1 R, etc.

My question to Canon is - Why be a Johnny-come-lately follower rather than an industry leader?

There is NO technical reason why Canon cannot make a full frame mirrorless camera that resembles the EOS-1 body and uses the EF native mount. It is totally doable. The compromise is made because the marketing department thinks more photographers will prefer a lighter, smaller camera - one of the main selling points of the mirrorless camera to begin with.

In a recent interview with the French photography site, Lens Numériques, Messrs. Mineo Uchida, Masato Seita and Shingo Hayakawa, (the people in charge of the EOS-R camera development) replied, when asked about IBIS (In Camera Image Stabilisation), one card slot and cropped 4K video :

"Yes, we are aware that mechanical stabilization is an important demand from the users, but considering the positioning of the EOS R, we decided not to integrate the IBIS […] because our priority was compactness. The compactness we wanted to have was not compatible with such a system. But of course, in the future, we will be able to answer them. 

This is our first model. We still have room for improvement. For the memory location, it is a question of compactness and priority for the photographers covered by the EOS R. We believe that one location is enough. And for the video, it’s the same answer. We believe that the intended target will be satisfied with the proposed modes."

The use of an adapter and the small size of the EOS-R prevent the new camera from functioning like the tradition EOS high end models. Personally, I am not willing to make this trade off to gain compactness and a little weight reduction.

The EOS-R may find a home with serious landscape, nature and portrait photographers. For the casual users, the EOS-M series of cameras will do an adequate job. I doubt many serious and professional sports or wildlife photographers will buy this or the 'pro' model coming in 2019.
