GoPro may soon deliver the fourth evolution of its popular action camera. A small gadget website called DGISE, posted the purported specs of the new GoPro Hero4 that supposedly can record in 4K at 30 fps. Although the two-year-old Black Edition GoPro 3 was also able to shoot in 4K it could only do so at a paltry 15fps. This higher frame rate could make 4K footage from a GoPro camera actually decently viewable.
Along with the quadruple HD resolution, the new camera will supposedly feature 1080p recording at 120fps and 720p at 240fps. On the still capturing front there is also Multi-exposure HDR and Wide Dynamic Range tone mapping. Meanwhile to keep all the rocking action steady the camera purportedly has an electronic image stabilization system backing up the camera’s 13MP sensor. DGISE also posits the GoPro Hero4 will have a completely new lens for shooting in dark and it will arrive this summer.
Given that this is a small and largely unknown source, we’re look to take these early specs with heavy skepticism. There are some merits to these rumors however. Many of the same specs were leaked back in September by Ambarella, the company that manufactures the GoPro’s underlying electronics system for several generations. It’s been two years since the adrenaline junkies started strapping GoPro Hero3s to the sides of the safety helmets…and pelicans, so we’re due for a new GoPro action cam any day now.
The Sony RX100 Mk II, just like the original RX100, sports a lens that has a bright initial aperture of f1.8 at its widest setting, but that gets rather slow towards its tele end where the maximum aperture is a mere f4.9. This is not untypical for compact cameras, as making the aperture much wider would also result in an overall larger lens. Still, newly unearthed patents show that the next iteration of the series could sport a lens with a brighter aperture at the tele end.
Published by Egami, the patent sketches five different zoom lens designs for compact cameras sporting a 1″ sensor, and all of them are very similar to the lens inside the currect RX100 (Mk II). One design in particular looks like a potential candidate for an RX200 camera, sporting the same focal length range of 28-100mm equivalent, but a brighter aperture that goes from f1.8 at the wide-angle end to f2.8 at the tele end.
Another design is for a lens with a longer zoom range of 28-150mm, and an aperture range of f1.8-3.6, which is also relatively bright considering the longer focal length at the tele end. Both lens designs sport 12 elements, arranged into 10 groups in the shorter lens and 9 groups in the longer lens. Also discussed in the patent is the addition of a macro mode, which would allow for very short close-focusing distances.
The way we see it, both of these lens designs would make sense for a successor to the RX1oo Mk II. A brighter aperture at the tele end is something that many RX100 (Mk II) users have been calling for, so the first option would satisfy that department. But a slightly longer lens that provides extra reach could also find a liking with many customers, especially if its aperture at the telephoto end is as bright as described in the patent.

When it comes to ultra wide angle lenses, Rokinon has always offered great image quality at an affordable price. They recently announced their 10mm f2.8 for APS-C DSLRs from our usage, we think that it is a pretty decent option for architectural and landscape shooters. The lens has a better build quality than previous offerings and can also deliver some spectacular images.
