Just when you think Sony have got it right you discover its far from it…Many cameramen and women are still waiting for their FS7’s to arrive, meantime the question is…what lens to buy.
Sony Broadcast may have had a hand in the specifications of the 28-135mm f4 lens but someone in Sony should have noticed its severe lack of wide angle due to the 1.5x crop factor on the Super 35mm sensor taking the 28mm end to 42mm. Its become obvious that this full frame lens was never intended to be used with a Super 35mm sensor camera.
The reason the FS7 is so popular is many of us are fed up with the static manual lens DSLR “look” and want to get back to a camera that not only looks the part but performs with more than one function hence the run and gun problem.
You only have to look at the internet boards to see everyones dilemma, yet again, about which lens to buy for run and gun…this should not have been an issue if Sony Broadcast had a specific lens made for a S35mm sensor. The 28-135 works fine on a Sony A7s as this has a full frame sensor but is top heavy for such a small camera in my opinion.
We seriously need a WA zoom for this camera that does not cost a fortune like the Canon zooms at a ridiculous £25K. Sony have proved you can produce 4K servo zoom lenses for just under £2.5K.
As a comparison of a good run and gun camcorder lets take the Sony PMW-400K, this has a 2/3″ sensor and comes with a 16X lens with an acceptable 31.5mm wide angle, this is Sony’s stock lens for the 400 which is only £1,686 dearer with the lens and its a lot faster at f1.9 !
People have said “but look what you are getting for £2.5K” not realising for £1.7K Sony make a 16x 2/3″ lens so why can’t we get a 10x wide angle zoom for the Super 35mm sensor ?
Many of you say you can, its the 18-200 f3.5-6.3 lens as seen on the FS700…so why is it not marketed with the FS7 simple its not “professional” enough, they were designed for semi pro use and thats obvious by their design.
When Sony brought out the E18-105 f4 lens (£450) for the NEX-EA50, they made sure it was wide enough for the S35mm sensor.
Again the same scenario with the FS700 we get a Sony 18-200 lens (£900). In fact one of my readers has asked why not use one of the 18mm zoom lenses, that might be an option but the lack of aperture ring makes these lenses more awkward to use and manual focus is awkward.
Sony have been bringing out 18mm (1.5x crop factor 27mm) for the last two S35mm camcorders yet the one thats taking the world by storm and the most technically advanced is marketed with a full frame 28-135mm servo zoom…why has this been allowed, Sony must have known all along this lens would compromise the FS7 yet it has been allowed to happen…shameful Sony !!!
With NAB 2015 just around the corner lets hope Sony have a wide angle 4K 16mm – 150mm f2.8 servo zoom lens to show off or to be more practical an 18-135 f4 would hit the mark.
