Round Up: Sony 600mm f/4 GM and 200-600mm f/5.6-6.3 Coverage

Above is probably the best summary of the war between Sony, Nikon, and Canon. The Sony 600mm f/4 GM and 200-600mm f/5.6-6.3 have really rounded out Sony’s mirrorless system and there really isn’t a good argument for Nikon or Canon technological dominance anymore.

My friend that runs our sister sites has always commented on Sony’s lack of long glass whenever I compared Sony to Canon/Nikon and the minute I leaked Sony’s 200-600mm and asked him if it would satisfy him he said he would rather have Nikon’s 600mm f/4. Well now Sony has a 600mm f/4 that likely dominates the competition with its superior G Master design so now what will it take?

Sony is dominating this generation of cameras and Nikon/Canon are too far behind to catch up without obscene amounts of investment. Sony has spent billions of dollars year over year on mirrorless R&D since entering the mirrorless market while Canon and Nikon have spent conservatively to secure in their market place position. It is unlikely either will catch Sony soon with their mirrorless camera system, which should help Sony win the war to come.

Should Sony’s Sensor Business Spin Off?


Activist investor Daniel Loeb is calling for Sony to spin off their sensor business and he even set up a website astrongersony. The 102-page presentation and 7-page letter is interesting and I will likely read it all, but does anyone agree with him? Activist investors have been getting too much attention in recent history, which has lead to a lot of undeserved power imo.

Financial Times (behind a paywall) just published an article entitled “Daniel Loeb calls on Sony to sell sensors business.” Loeb’s Third Point, in a letter to investors today, according to the FT, publicly acknowledged it had built up a USD$1.5B stake in Sony. Loeb is apparently calling for Sony to hive off its sensors business, listing it in Japan as a separate company. Apparently, Loeb has set up a website laying out his thesis. Sony and Loeb previously tangled back in ’13.

Sony’s Engineering Prowess Proven by Fujifilm Value Angle Calculation and Misinformation Being Spread Again

Profifoto and Docma have tried to run with Fujifilm’s value angle figure using the following formula:

Value Angle = 2 × arctan ((2 × Pad Ratio) / (Port Diameter – Sensor Diagonal))

But they got something wrong because their figures do not match Fujifilm’s calculation table.

Their table did help use decode Fujifilm’s original table over on FujiAddict thought, which shows that the Sony NEX has a great value angle, while the Sony FE system has a very bad one at 5.50. If these values are evident of a manufactures ability to deliver image quality then Sony must have some amazing engineer.

This way of calculating the quality of a mount could be of significance from an engineering perspective, but it really shouldn’t matter to photographers, beyond the possibility that engineering challenges can lead to higher prices. Sony has been very open about using software to fix optical weaknesses in their cheaper lenses and they probably do so in some of there GM glass, but GM glass pushes the limits of optics so it is probably incredibly difficult to make with such a low value angle as measured by Fujifilm.

To summarize I do not believe any of these numbers should matter to photographers, but it might make engineers lives easier when trying to design extreme lenses with maximum image quality. If Sony had a better value angle their GM glass might be cheaper or more profitable, but most entry-level cameras and lenses have been sufficient for most photographers needs for years now. We should take manufactures numbers with a grain of salt because everyone is doing their own thing and right now Sony is leading the way with features like their eye AF.

DPR Sony Interview: Sony 600mm f/4 GM, 200-600mm f/5.6-6.3 and More


DPReview attended a launch event in NJ for the Sony 600mm f/4 GM and 200-600mm f/5.6-6.3 launch. During this event, they spent time interviewing Yasuyuki Nagata, head of Sony’s global interchangeable lens business. You can read excerpts from the interview below:

  • The Sony 400mm f/2.8 sold much better than expected – actually double what was expected
  • Top photographers are using the Sony 400mm f/2.8 at sporting events
  • 70% of 400mm users are professionals
  • The 400mm f/2.8 has a long waiting list
  • The 600mm and 200-600mm are more for high-end amateurs that shoot birds, wildlife, and aircraft.
  • 70-80% of 600mm and 200-600mm owners will shoot wildlife which is why the market is bigger for the 600mm than the 400mm.
  • Some will use the 600mm and 200-600mm on APS-C cameras to get more reach
  • The 600mm f/4 is big but 10g lighter than the Canon EF 600mm f/4L IS III USM
  • G Master lenses like the 600mm have no compromise and represent future lenses for today
  • G lenses like the 200-600mm have some compromises in areas like materials or the body
  • The 200-600mm lack magnesium-alloy and the newer XD linear AF actuators (they aren’t really needed)
  • G lenses are also supposed to be more affordable
  • GM lenses always have new technology developed for them that didn’t exist before
  • Sony is considering future camera bodies with GM lenses too like the rumored a9II
  • Sony designs their GM lenses for more focus calculations per second and faster frame rates than the a9 can achieve
  • Sony is keeping its telephoto switch/button layouts consistent
  • Future a9 cameras will have more speed, less weight, greater usability
  • The Sony 200-600mm supports video functions because many shoot video and photos, which is why Sony used linear action AF actuators
  • Mechanics and optics factor into video performance, but Sony also thinks they have the best camera bodies due to their integration
  • Sony zooms are always trying to reduce focus breathing and axial shift, which can be bad for video
  • The Sony 200-600mm zoom is an internal zoom and a lot of its length comes from the hood, which is removable
  • If you are a serious shooter the 600mm is for you and its probably as good as the best competitive alternatives, but Sony’s integration exceeds others
  • At this time the Sony a9 has no competitor and its performance is the best
  • Sony wants many photographers to carry the reasonably priced 200-600mm and they even built it to support their teleconverters
  • Different bodies will make these lenses perform very differently, but they are nowhere near their performance limits at this time these lenses will be much faster on future a9 cameras
  • Sony is designing for its lenses to keep up with the next generation of cameras
  • Sony thinks about compatibility between the mechanical parts, electrics, even software when designing lenses
  • Others talk about channels for communication between the camera and lens, but Sony says that doesn’t matter unless the actuators can keep up
  • Sony is still pushing glass weight closer to the body so lenses handle better
  • Keeping the size and weight down is the hardest part of designing a lens
  • At least 10% of 400mm f/2.8 owners bought teleconverters
  • It takes a very long time for lens technology to filter down to consumer lenses because lenses aren’t updated often
  • High-end lenses should stand as benchmark performers for about 10 years
