  1. Now is a difficult time as with S1 and S1H there aren't so many lenses and with MFT the future isn't so clear. If you can possibly hold off then that would be the smart move..
  2. Society will always have things that they're not willing to talk about, and when someone does talk about them there will be controversy. Hollywood is relatively new to this territory, but it's the job of the artist to address the unaddressable, to discuss the undiscussable, and to generally bring these things to light. That's why there's so much dark humour - we laugh partly because we don't know what else to do. "I can't believe you said that". Check out Sarah Silverman, deeply wrong and also hilarious.
  3. My first hard drive was 20Mb. I got a second one that had been physically opened and was now unreliable, so I had to run Spinrite every week (it would read the drive and re-write the same data over the top to refresh it) otherwise it would just stop working and you'd have to format it again. That process took about an hour because it was so much data. At full-IQ my GH5 would fill one of those hard drives every 0.4 seconds. 8K will be mainstream, just wait long enough. and after that it will be vintage, then it will be positively pre-historic.
  4. Will this be solely the IBIS? or is this from trying to stabilise it in post? IIRC these stabilisation artefacts happen from the combination? I wonder if there's a plugin that will be able to un-do these things? It should be relatively easy as it's just parts of the frame stretching without other parts stretching.
  5. We can compare 6k to 1440p, but we should also compare it to 720p, as both were the lower of two standards that got announced together (or at similar times, not sure). And 720p is still being used as a broadcast resolution in the US, so we might be having the "is 12k ever going to be used when there's 20k" conversation and someone will be saying "there's a VR app in the US that's only 6k" ???
  6. All traditional discussion will be put aside when people start talking about VR where you're heavily zooming into the delivery image when viewing it. My phone is 1080p and it looks like YT 360p when I'm using it with the VR adapter goggles (and it becomes a pair of ~1000x1000 eyepieces). For 360 degree VR video you're going to want more resolution for quite a long time - we are a very long way off from retina resolution VR.

    I think it will come down to what extra width vs low-light is worth to you. You can also compromise your wallet instead and get the Laowa 7.5mm f2, but it's much more expensive! The SLR Magic isn't a nice lens to use ergonomically, but it puts out a decent image so if you're shooting in slower more deliberate situations then that might not matter. Also worth considering is the Panasonic 14mm f2.5. It's nothing special, but it's similar to what you're talking about so just thought I'd bring it up in case it slipped your mind.

    Why? People have been discussing lenses and posting images and screen grabs from lenses. If this isn't the purpose of a thread about lenses then I'm not sure what is... Just because someone complains doesn't mean we have to go all scorched earth or move to a new country and start again
  9. Absolutely not! Bonus points for interesting and strange choices!! If you're super-keen, there are medium-format lenses available (and even large format lenses too!!) so you could get a medium-format to FF speed-booster or even a medium-format camera Oh, I don't know... put 135mm on a FF and make it part of a 2X anamorphic setup (I have no idea if this can happen, but I'm telling this story so whatever...) and you'll have a widescreen 67.5mm horizontal FOV. Sounds pretty good to me! @leslie might do it!!
  10. lol.. the lens sub-forum should be relatively safe Remember to take crop factor into account, 85mm is pretty long to begin with. Unless the anamorphic adapter will make it wider? I'm not so sure how these things work
  11. I agree that oversampling creates an IQ benefit, no doubt, and of course downscaling to 2K gives 4:4:4 colour whereas a 1080p sensor does not, so it's not a perfect simulation. However, my original point was that you can take a lower resolution and sharpen it a little and it's indistinguishable from a higher resolution with no sharpening. This test is a little different in that there's no processing to try and match them visually - this is just a "here's what they all look like" test, and we see what we see and make our own conclusions. I draw the conclusions that between 4K and 2K there is very little difference, and if we're comparing 8K with 2K there absolutely isn't a 16x difference!! That's my impression - without seeing them side-by-side you wouldn't really look at good quality (or RAW) 2K and be completely disappointed by it.

    I don't think I saw this posted here yet... Lens test from Reduser.com Here's the thread on reduser.net with all the details: http://www.reduser.net/forum/showthread.php?177346-The-Agony-Of-Choice-Vintage-Modern-Lens-Shootout
  13. Ah! Sorry - my brain just caught up
  14. Whose whole point? Between what and what? I'm curious what setups you guys are looking at this footage on? and which file were you looking at? I'm simply testing the theory that sub-4K resolution is a desirable factor that the people who like the 'filmic / cinematic / classic' look of the Alexa or 1080 BM cameras. If you guys are fans of the highest resolution image possible and are looking at these videos on huge displays then that makes sense. If I zoom in to 100% of the original in Resolve I don't see any significant difference, or a difference that I really care about. This is probably taste though.
  15. I played with 10-bit vs 12-bit vs 14-bit on my Canon 700D with ML RAW and didn't see that much difference, so I just decided that 10-bit was enough. Not to say there wasn't any difference, because there was, but it was fairly slight I thought. Then again, not that much DR with Canon and I didn't shoot many actual videos with it, so a few caveats. You might already be doing this, but are you taking your final exports and creating LUTs to try in-camera? (your wording wasn't clear above, so not sure if that's what you say you're already doing..) You might also be able to take one of the standard LUTs, apply some additional corrections, and then export that as a LUT to use?

    Posting frame grabs makes sense to me as they're far less compressed than posting a YT or Vimeo video. Posting stills is even better as it shows the capabilities of the lens in more detail. There are other aspects to lenses, but surely seeing what the image looks like through them is a pretty big part of a lenses performance? and if not, what else would you like to see that we're not talking about?
  17. I'm an amateur that can't get it right in 8-bit.. That's why I shoot in 10-bit on my GH5 ???
  18. In the absence of BM footage I was wondering how much the look the resolution plays, so I made this test (also posted to another thread for another reason). The method was I started with an 8K RAW clip from a RED Helium and exported it to Prores HQ at 4K, 3.2K, 2.5K, 2K, and 720p, then added the original and the exports back into a 4K timeline for comparison. Here's the export on YT: Here is the h.264 export download link: https://www.sugarsync.com/pf/D8480669_08693060_6462598 and here is the Prores LT export download link: https://www.sugarsync.com/pf/D8480669_08693060_6462579 I'm very curious to hear which resolution (if any) reminds you of the cinematic look of either an Alexa, or of the classic BM cameras?
  19. Did this test to see how visible resolution differences are. The method was I started with an 8K RAW clip from a RED Helium and exported it to Prores HQ at 4K, 3.2K, 2.5K, 2K, and 720p, then added the original and the exports back into a 4K timeline for comparison. Here's the export on YT: Here is the h.264 export download link: https://www.sugarsync.com/pf/D8480669_08693060_6462598 and here is the Prores LT export download link: https://www.sugarsync.com/pf/D8480669_08693060_6462579 I'm not convinced there is much difference until you're approaching 2K or 2.5K.
  20. Or, in my case, when the battery is getting lower and they start throttling the CPU. Then it's time to give it to one of the kids as a hand-me-down! ??? (also, at this point the camera will be a noticeable upgrade!) Mine has a slider called Tint, but it adjusts temperature (blue/orange), not tint (green/magenta). Has that changed?
  21. Ah!! I was thinking of filming where the camera had to be mobile, like skateboarding videos, skydiving videos, skiing and snowboarding videos, etc... I didn't think about the situations where the action is taking place right next to large tripods that don't have to move! ???
  22. No reason you can't shoot in whatever you like and downscale - 8K RAW if you feel like it! I think it does, but maybe not during new camera season...
  23. And for those who have a bit more to spend and want something truly special, there are things like the Jupiter-9 85mm f2 lens with its many (15?) aperture blades: and here's one of the early m39 versions that are supposed to have the better optical quality than the later m42 ones for US$129: https://www.ebay.com/itm/1965-Jupiter-9-85mm-f-2-M39-to-M42-SLR-lens-85-2-Canon-Pentax-GOOD/303104196284?hash=item46926afebc:g:if4AAOSwZmJclNiV Think about what modern lens you can buy for $129 - basically nothing worth having, so try to keep this in perspective for what you're getting!
  24. A few thoughts: Make sure to search ebay.com as it includes auctions that will ship internationally that won't appear on other ebay sites There are lenses for all budgets, for example the Industar 50-2 50mm f3.5 is available in great condition for US$20 including free worldwide shipping https://www.ebay.com/sch/i.html?_from=R40&_nkw=industar+m42&_sacat=0&LH_TitleDesc=0&_sop=15 There are the classic Helios 58mm f2 lenses available from US$30 including free worldwide shipping If you want wider than a 50 (good for cropped sensors) then for US$34 the Industar-69 28mm f2.8 (with m39 to m42 adapter) might be a good choice [Edit: although apparently the flange distance is some odd Russian custom thing so you'll need to mod your adapter and it's also not FF - so maybe not for the newbies then!) https://www.ebay.com/itm/Industar-69-Soviet-lens-28-mm-f-2-8-adapter-M39-M42-USSR/253845769361?hash=item3b1a630c91:g:SpoAAOSwksBbaX4b Or you can get the mighty APOCHROMATIC Mir-1B 37mm f2.8 in open-box / as-new condition for US$45 plus shipping https://www.ebay.com/itm/MIR-1B-2-8-37mm-Wide-Angle-USSR-SLR-mir-1-v-lens-M42-Flektogon-copy-NEW/254293234460?hash=item3b350ed31c:g:wAMAAOSwOSVdJy3U There are heaps of cool and interesting lenses available!! I've placed (at least) one order ???
