dark goob: I applaud DPreview for not mentioning "equivalence" in this article, and for not calling Super35 a "crop sensor".
I'm glad we've finally evolved beyond calling things "full-frame" vs. "crop". Clearly, when Canon's most advanced optics by far are made full-frame relative to Super35 (24.9x14mm), which is much smaller even than an 16:9 APS film frame, we are finally in the future where 135-format's long dominance over the cultural milieu has ended.
Maybe now DPreview would be open to switching to using Range Factor terminology. This lens is a 2.01:1–41.08:1 Range Factor. The ratio is D:W, where D=distance-to-subject, and W=width-across-frame. I.e. a 1-foot ruler will occupy the entire width of the frame left-to-right from 41.08 feet away at 1000mm. With the extender it increases to a max of 59.76:1.
"Compare" this to a Canon SX60HS which has a Range Factor of 0.62:1–39.55:1 on its 1/2.3"-format (6.2x4.6mm) sensor, which is a 27% crop of Super35.
Well, I don't think that having a foggy, milky "intuition" or "feel" for something really counts for much. Sounds like what new age people say about the spiritual power of crystals.
What that "intuition" actually is, is just a feeling of familiarity and recognition, and a vague idea that only approximately corresponds with reality. It's not actually useful for anything specific. It has no degree of precision. Very complex math involving trigonometric equations and squares is necessary to determine anything useful from it about the angle of view or the extent of the captured frame at a given distance.
Further because camera manufacturers report the *actual* aperture but only the *equivalent* focal length, then it leads to even more confusion for consumers. This is bad.
The first step is moving away from 35mm-equivalent focal lengths and only using Range Factor (or something similar), while also ditching the idea of calling 35mm "full-frame" since "full" is a purely relative term.
@random78 In that respect I have no sympathy for people who say "we have to develop the intuition all over again about what those mean" because first of all, I highly question the idea that anyone actually really does know "what those mean."
I'm sure you know what the normal focal lengths "mean": 24, 28, 36, 50, 70, 85, 105, 135, 200, 300mm, etc.
But what about 247mm? 12.9mm? 21.4mm? 43mm? There are an awful lot of weird ones nowadays if you actually do the conversions and don't round it up to the nearest decimal (which is especially dumb to do at the wide end). I challenge anyone who thinks they really know what these 135-equivalent focal lengths "mean", to honestly sit down and try to write down how far away you would have to be from a 6' tall person to get their whole body in the frame, top-to-bottom, with focal lengths of every whole number from 1 to 50.
Now I'm sure you don't know how to do that. Nobody does. So people will say, "yeah but I have a *feel* for those numbers."
@random78With all due respect, I am opposed to the idea that it is a bad thing to develop new ideas, new intuitions. I believe that is the benefit of being human: we are allowed to be creative, and we have the capacity to learn and to think.
Setting things up in a way that makes logical sense and is mathematically useful follows the spirit of photography. For example the F-stop numbers and flash guide numbers were developed to make it easy to determine the distance-to-subject necessary for a proper exposure using simple division, as opposed to having to perform algebra or trigonometry. The disadvantage to using degrees (or hey, radians!) would be that almost no one can perform arctan in their head. Sorry, but you can't.
The advantage to the Range Factor idea is that, like guide numbers and f-stops, it deals with distance-to-subject and only depends on simple multiplication.
If your range factor is 41:1 and your subject is 3-meters wide, 41x3 = 123 meters distance-to-subject.
I applaud DPreview for not mentioning "equivalence" in this article, and for not calling Super35 a "crop sensor".
Imagine if Apple did this.
They would never live it down. Never
Brace for epic... BRACE FOR EPIC...
...wait for it...
... BOOM! YEAH! That was it!
Hahah! Yee-haw! I *know* that was the most epic set of "..." you've ever seen. Aren't I awesome?!
No wait I got it!CHEAP PRINTER INK!!!!
Possibilities:Updates Rebel t2i to 4k.Home sensor replacement kit.That "digital film" roll we were supposed to get by now, y'know, the one that turns an AE-1 into a dslr.Apple buys Canon. BlueTooth MIDI control for DSLR.Built-in RF wireless flash control.Cell phone by Canon! Canon actually enforces MAP policy thru Christmas! Serious now!Canon stops selling on Amazon and opens own site woot.Weather-sealed EF-S lens!!!!100 megapixels. <--- Winner
If Hollywood concentrated on making great movies instead of all this fancy-looking gear, we might have more than one great film every three to four years interspersed with schlock-show after schlock-show. The epic scale of this wasteland is only dwarfed by the scale of the money and talent wasted to create it.
Why does the guy mention a DSLR in the last quote? Crack smokers.
Maybe the Nikon factory got contaminated by Fukushima radiation. Check your camera with a geiger counter. Better to be safe.
photohounds: I see all the usual u4/3 haters have crawled out of the primordial slime, crouched in dimly lit alcoves, mutting incantations over big and holy sensors.
The rest of us take pictures and enjoy photography more than brochures and knackered backs. http://photohounds.smugmug.com
Damn strait. I thought Yoda settled the "size doesn't matter" argument in 1981. Evidently people haven't been watching their Empire Strikes Back enough these days. Hopefully JJ Abrams will soon indoctrinate the new idiots in how size doesn't matter with this upcoming Star Wars sequel of his.
By the way I wonder what sensor format he is shooting it in?
This is just wrong. Super35 is 24.9x16.6.
21x12 is the same thing BlackMagic's Production Camera uses.
For Reference the GH2's multi-aspect sensor is 18.9x10.6mm at 16:9.
Retzius: Or, you can just wait 6 months and it will be on firesale for $399.99
Putting this camera in the same category as Micro Four Thirds shows that DPReview has absolutely no integrity, no understanding of photography, no real knowledge of photographic equipment, and no soul. DPReview has become purely Amazon's advertising agency and is not worth reading.
Musicjohn: So when are manufacturers going to design a photo-camera which excells in taking photographs (just as the word PHOTO-camera implements) instead of concentrating on video features? If I want to make superior video images, I'll buy a video camera instead.
Musicjohn you are an IDIOT. 4k video is 8 megapixels PER FRAME. I have blown up 4k frame grabs from a RED up to 24x36" and they look SPECTACULAR.
You just DO NOT know what you are talking about. Life moves. 4k lets you capture life. Grab your still from it later!
Ulfric M Douglas: I'm interested to see what all this huge power means for it as a stills camera.Could be good.
Dude. 4k *is* stills.
springsnow: LOL @ the Zeiss iPhone case.
Yeah way to sneak the Zeiss logo in there :/
It's gonna be the same sensor as the D4 and cost at least $3,000.
Nikon: resurrecting 135F-format one old, wealthy white guy at a time.
vFunct: Has anyone ever seen a professional photographer at a press event use anything BESIDES a Nikon or Canon?
All other manufacturers are a JOKE compared to these kings.
Mirrorless camera's are even WORSE than jokes.
There are absolutely ZERO Photojournalists in this world that use a mirror less camera. They are completely useless!
The only people that use mirror less cameras are measurebators! HAHA!
Really kiddos, stop playing with your mirror less camera and get a grown up camera like a Nikon.
Seriously, has anyone actually ever seen a photographer at a press event that uses anything besides a Nikon or Canon?
Of the 150 photographers at Fashion Week or a Sporting Event, I noticed that ALL used Nikon or Canon. HAHA!
All the other cameras must be used by girly weaklings.
I was at a press event with my E-M1 the other day. I had to step over homeless Chicago press photographers who tried to sell me their D4's on the way in.
