Hugo808: How big a screen would I need to actually look at a 100mp file without it being compressed?
Depends on the DPI of the screen.
river5: No OM.Why?We old olympus users have many OM lenses.Hope they manufacture one adapter for us.
OM lenses adapt well to Canon EF and there are plentiful Canon EF speed boosters. You can use a cheap $10 basic OM-EF adapter in between the Canon EF-m4/3 focal reducer and you have an OM-m4/3 solution.
photophile: bit confused - when they say it "increases the F number" - I presume they mean it increases the size of the aperture - in other words it decreases the F number - so that an f2.8 becomes an f 2.0 (hence speed "booster"). Or is it the other way round ??
Speed boosters work by reducing the focal length while keeping the aperture the same size. If we have a 50mm lens with a 1/1.4 f-ratio, that has about a 50/1.4 = 36mm aperture. If we reduce the focal length by .72 so we are at 36mm, now we have a 36mm aperture/36mm focal length = 1/1 f-ratio.
1/1 > 1/1.4, so the f-ratio (or f-stop) has in fact increased. However, the value of the ratio when applied to the focal lengths has not increased. 50/1.4 = 36/1 (rounded)
Andreas Stuebs: I would love to see a Pentax K adapter to Micro4/3
Pentax K adapts OK to EF mount with a $10 simple mechanical adapter. Buy any Canon EF speed booster and add PK to EF adapters to your K mount lenses.
fireplace33: I have quite a basic question.At the moment I use a Nikon D7100 with a set of various FX & DX lenses Does this type of adapter mean…I could take my current collection of DX and FX (Nikon and 3rd party) lenses (please see which ones in my gear list)and attach them on the Nikon version of the adapter and then use them on a micro four thirds camera? If it works, what disadvantages might I expect using my existing lenses compared to using equivalent specifically designed m43 lenses?If it works, what would be a good m43 camera to consider for this ?Thanks for your feedback
They are primarily designed to adapt the vast library of old film lenses that are manual aperture and manual focus. Especially these ones since the cover 3 lens mounts that never had AF or auto aperture.
As an example of how they can be useful, you can take an old Minolta 58mm f1.4, which is about $50. Use this $150 adapter and now you have a 42mm f1.0 prime for around $200. Voigtlander makes an all manual 42.5mm f0.95 prime for m4/3, but it is nearly $1000.
Right now they only mount that offers reasonably seamless AF adaptation with a focal reducer is Canon EF mount to both Sony and m4/3.
rpm40: Holy crap, I have never seen such a spectacular collection of curmudgeons and complainers line up like that before- lets see it in low light...the rig is too expensive...they calculated the resolution wrong...more free ads for Sony...You guys must be a blast at parties.
Holy s#!t, guys. Of course it is an Ad. Chill. Enjoy a fun little project. I look forward to the progression of VR.
The Squire: Did someone in Sony marketing do that math?
"So 12 cameras, each shooting 4k... that must mean it's a 48K video! WOW! Press release... done!"
Doesn't account for the need to significantly overlap the output from each individual camera.
If there was *no* over lap, then shooting those cameras in portrait and stitching together gives a theoretical output width of 12x2160px = 25.920px... aka 26K?
When pedants and marketing collide...
Does it matter? You can only view 4K at a time anyway.
Not too shabby. I don't think I'll buy one, but I'd be lying if I said I didn't miss the "real" keyboard from time to time.
justmeMN: Oh goody, another DPR Sony Infomercial.
Wait, I thought they were Apple parrots. I can't keep it straight anymore.
This is the kind of video that makes sense for VR. Looking around naturally and the scene is occurring all around you as if you were in it. That's very interesting!
Scrolling and panning around kind of makes it feel a lot more disconnected.
otto k: Rant:The video is impressive but I fail to see how this is 48k in any possible meaning, other than marketing fantasy talk. The phones are in portrait orientation so each individual video is 2k wide and 4k tall. If there is zero overlap (doubt it) it would produce 24k x 4k video.
Marketing guys are ruining the world...
It does have 12x the resolution of 4K, assuming no overlap.
All brand bashing aside, this seems like a great idea to get a little zoom into camera phones.
Dougbm_2: How is this ultra wide?
A Camaro SS is still a sports car even if it isn't that sporty compared to a Ferrari 458 Italia. Just because some UWA are wider, doesn't mean this isn't a very wide lens. 21mm equivalent is very wide compared to the "Standard" wide angles of 24-28-35mm.
MikeManr: Unfortunately, this camera doesn't have swiveling tilty screen, which I wanted.
boo keep it small.
havoc315: So a big heavy ultra wide angle lens... That really isn't too ultrawide. Equivalent of 21mm.... I don't see much of a point to this lens.
Samyang 12mm f2.0 for Sony E-mount, Voigtlander 10.5mm 0.95 for m4/3, voigtlander 21mm f1.8 for Leica, Sigma 20mm f1.4 for FF DSLR - just off the top of my head.
But surely none of them have ever sold even one copy, right?
Mister Roboto: What the hell is wrong with these companies trying to put a makeup on a pig? iPhone has pathetic camera module so what is the point?
When I said "camera on the market" I meant "phone". Sorry for the typo.
Say what you want, but the iphones crank out the most consistently pleasing images of any camera on the market. Not the best in terms of absolute quality, but if you aim, point and click it's going to get you a usable image almost every time that doesn't need editing. For many people that makes it the best camera on the market.
If people aren't even willing to carry a slim compact with an internal zoom, what makes anyone think they are willing to pack a somewhat expensive and chunky lens with a big ugly cage they have to strap on their phone.
What is the market for this? It seems like anyone who would care enough to pack this much gear with them would already be fine carrying a camera and also wanting better image quality.
ceonupe: we are witnessing the final days of the point and shoot. other companies will do this also and a few phone makers will have a micro lens mount directly on the camera. (think samsung galaxy nx camera but smaller)
People will spend real money on these if they work and work well assuming the phone makers themselves dont just put better lenses or optical zoom options directly in the phones
