7Artisans goes wide on the RF mount


7Artisans is one of those Chinese lens manufacturers that have popped up in the last 10 or so years. I played around with 7Artisans on the EOS-M mount, and they were pretty fun bang-for-the-buck lenses, but quirky ergonomics.

7Artisans is known for its manual focus, and manual aperture lenses, and this 9mm F5.6 full-frame lens is no different. However, with 16 elements and 11 groups, it’s not exactly a simple lens either.

The craziest thing about this lens? It should cost somewhere around $375 if this specification sheet is correct. What grabbed my attention was the MTF data. If this is actually what this lens can do, it’s a pretty good lens. Yes, it’s all manual but who needs AF at 9mm anyways? As an example, the widest Canon-made RF lens (Canon RF 14-35mm F4L) falls off more to the corners and has greater astigmatism according to the MTFs – and it’s 14mm versus 9mm.

Craig actually has the lens, so hopefully, we’ll be updating this post with some real-life examples.

This has the makings of a very interesting lens for the RF Mount.

DJI debuts the new Mini 4 Pro, a sub-250g model with advanced tech and longer flight time: Digital Photography Review


Image credit: Kara Murphy

Today DJI announced the Mini 4 Pro, the latest model in its Mini series of compact and foldable sub-250g drones. The Mini 4 Pro is the first in the series with omnidirectional obstacle detection and avoidance and Waypoints. It also features True Vertical Shooting, perfect for platforms that use vertical video. On a single charge, the DJI Mini 4 Pro can remain airborne for up to 45 minutes with the right battery.

The single camera on the Mini 4 Pro has a Type 1/1.3 CMOS sensor with dual native ISO, a 24mm (equiv.) lens, and a fixed F1.7 aperture. It can capture 48MP images and rests on a 3-axis gimbal that can tilt 60º upward. The camera is capable of cropping in up to 2X for photos and up to 4X when capturing video.

Video can be recorded at resolutions up to 4K/60p and 4K/100p for Slo-Mo shots in 10-bit D-Log M – DJI’s log profile that offers over 1 billion colors. Night Shots video mode, which allows you to increase the ISO to 12800, is also selectable.

The Mini 4 Pro offers a variety of creative features. The ability to capture 180°, Wide Angle, and Vertical panoramas, hyperlapse clips, automated Quickshots (Dronie, Circle, Helix, Rocket, Boomerang, and Asteroid modes) plus MasterShots, which shoots a variety of automated modes and stitches the clips together, are all included.

FocusTrack, which allows you to designate a subject and track it, is available in three modes – Spotlight, Point of Interest, and ActiveTrack 360°. The Mini 4 Pro’s body is equipped with six fisheye vision sensors on the front, top, and bottom of the aircraft for omnidirectional obstacle detection and avoidance. You can either brake in front of or bypass an obstruction.

The Mini 4 Pro is the first drone in the Mini series to offer the Waypoints Flight function. This feature allows you to pre-plan flights and repeat them. Cruise Control is also available and gives you the ability to automatically operate at a consistent speed and avoid potential flight fatigue while recording footage.

DJI equipped the Mini 4 Pro with its OcuSync 4 (O4) transmission system, giving it a range of up to 20km (12.4 miles). While you may never fly that far, this gives you 1080p/60p FHD video transmission while operating the drone. It can also remain airborne for 34 minutes with a standard Intelligent Flight battery and up to 45 minutes with the Intelligent Flight Plus battery. Using the latter power supply will place the drone at a takeoff weight above 250g, removing some of the benefits of flying below that threshold, like not requiring registration.

A super-wide 100° FOV wide-angle lens and ND16/64/256 filter set can be purchased separately for the Mini 4 Pro. DJI also created a 360º propeller guard set for comprehensive physical coverage.

Each Fly More Combo includes three batteries and an RC 2 Remote Controller.

The Mini 4 Pro with DJI RC-N2 Remote Controller and one Intelligent Flight battery starts at $759. This same package, with the RC 2 Remote Controller, is $959. The DJI Mini 4 Pro Fly More Combo, which includes the RC 2, three Intelligent Flight batteries, a two-way charging hub, and a carrying bag costs $1,099 while the Fly More Combo Plus, with Intelligent Flight Plus batteries that power the drone up to 45 minutes, comes out to $1,159.

Canon Dual Fisheye Mark II


There are times I see a cool patent, and look at it and can’t for the life of me explain what it does. I still may have gotten this one wrong, but I don’t think so. I actually sat on this patent all weekend and even forced Craig into an Irish triple expresso before finally writing it up.

In this patent Canon is describing the Canon RF dual fisheye lens, but with a twist. They want to be able to control the 3D effect and also change the distance the two lenses are apart when the aperture changes.

However, you can’t just slide the lenses closer or further apart along the camera axis, as it would change the length of the optical path internally in the lens. So to accomplish this and still be able to vary the distance between the two lenses, Canon has implemented a rotating geared assembly that would rotate both lenses thus changing the distance between the two fisheye lenses, but internally the light path would remain the same length.

Would Canon make a Mark II of the unique Canon RF 5.2mm F2.8L Fisheye? It’s hard to say that there’s one in the look given the fact that the current one is only a few years old, but Canon is always looking ahead to interesting things that make us go “Why on earth did they think that was a good idea?”, so here we are.

As with all patent applications that I drag in here, they are simply the applications, they may not be a future product or even a real patent. It does, however, give us some ideas about things that Canon is studying and possibly working on for future projects.
