  1. There would be a lot of resistance from A7x 'still photographer' users (the bulk of the buyers), to a larger body. One of the major attractions of the A7x series is the relatively small body (not everyone is coming from bulky DSLRs) and not everyone is putting large bulky lenses on their A7x. Remember Fuji tried this with the X-H1 and it didnt sell well. The A7siii is a different story though. Clearly it is for video shooters and they tend to prefer bigger bodies and would accept it for better video. We seem to have reached something of a 'crossroads' in terms of FF 'hybrid' cameras. It seems the tech (processors/sensor) is there to give 'stills' photographers exactly what they want - say an A7riv with a 60mp sensor capable of shooting 14 bit 'raw' at 10 frames a second. But for 'better video' we need 'more efficient processors' and/or bigger bodies - both of which 'add cost' but bring no real benefits for still photographers.
  2. I have had one for a few days but I am still trying to get to grips with it. Overall, it seems remarkably accomplished for a 1st gen product. They have got a lot right. As examples... 1) The startup time is incredibly fast - max 5 seconds. 2) The screen is both very clear and bright. 3) The touch interface is really fast and responsive 4) ..same with the software interface There are a whole load of gotchas admittedly. No face or active tracking in 4k 60p. If you really need to take advantage of 'pro' mode you need to attach a phone (although there is quite a lot of scope to switch between stills and video without a phone.) Battery life is pretty feeble (and seems less than the reviews I have seen). Audio quality issues might be partially down to two separate mics - one of which is right next to the control buttons that some reviewers might have accidentally covered up. Some of the advertised features 'story mode' and 'D-Cinelike' I dont think are in the app/camera yet. Difficult not to be impressed though. Biggest complaint from me is the lack of integrated wifi/bluetooth.
  3. Here are a couple of tests comparing Mac Pro, Imac Pro and a PC workstation for Davinci Resolve.... https://www.pugetsystems.com/labs/articles/DaVinci-Resolve-14-iMac-Pro-Mac-Pro-vs-PC-Workstation-1154/ And Premiere Pro.... https://www.pugetsystems.com/labs/articles/Premiere-Pro-CC-2018-iMac-Pro-Mac-Pro-vs-PC-Workstation-1142/ While they might be fair tests for iMac V. Mac Pro, it is worth bearing in mind that the company doing the tests sells PC workstations.
  4. I went to the Thailand Photo Expo yesterday and by far the most crowded stand was DJI with people playing with the Osmo Pocket (mostly in selfie mode). I think DJI will have a big hit on its hands here if it works as well as advertised...
  5. This absolutely kills smartphone gimbals if you ask me.... A typical smartphone weighs 180g. The Osmo pocket weighs 120g in total and the camera module that you are stabilizing, probably around 30g.
  6. I think the DJI pocket addresses all 3 of these issues. First it is so small (half the weight of a smartphone) that anyone can take it with them - no trouble - even if they dont use it. Second it has 'story mode' see 6.30 to 7.50 of this video.... ...this creates a video and does the editing for you - it even does all the camera motions!! Thirdly, it instantly edits and records the video on your mobile phone for instant sharing. Overall it seems a lot, lot easier to produce an interesting social media post than a smartphone.
  7. 82% of teenagers in the US use an iphone - so their phones certainly cost a lot more than US$350 https://www.digitaltrends.com/mobile/iphone-use-teens-2018/ GoPro 'primary' market is 14-25 year olds (investor.com), so there seems plenty of disposable income with teenagers (although they may well prefer a GoPro to a DJI Pocket.)
  8. If you go back a page you will see Tom's Tech Time's video. He suggests (doesnt make it a 100% clear) that there is no control over sharpening, noise reduction etc (even in pro mode) and as you point out the footage is oversharpened.
  9. I dont think this product is aimed at the majority of people on this forum but I think it looks really good for its target market - hobbyists who are allergic to normal gimbals and are looking for something unobtrusive and pocketable. I think it largely addresses a different market to the GoPro Hero 7. The size (arguably too small) does seem something of a breakthrough. Imagine a slightly bigger 'pro' version with the Mavic 2 1 inch sensor or the X7 with removable lenses.
  10. Don’t know about 8k myself - would definitely like to get away from 8 bit though.
  11. I read somewhere that the November 28th launch event is scheduled to be 2 hours long so with a bit of luck it will be more than just the Osmo.
  12. Big camera, small sensor. Didn’t work with 4/3 and Olympus. No reason to believe it will work for M43 and Olympus...
  13. I enjoy travel photography most but I have no doubt that the only stuff I do that will stand some reasonable test of time - is the family stuff. Just finished a book of photos of my son’s first 5 years....
  14. However, given that EOSHD Pro Color for Sony cameras is primarily designed to bring 'Canon colors' to 'Sony cameras' that in itself does show your inherent bias. It presumably means 'Canon colors are good' 'Sony colors are not so good' but we can make them better by adjusting them towards Canon colors.
  15. I think the basic term 'color science' is ripe for argument. The fact is there is an awful lot about 'color' that is 'subjective'. Everyone 'sees' color differently, colors (and luminosity) look different to the same person when set next door to different color and luminosity. Even our mood effects how we see colors (as in the expression 'seeing red'). And then f people say there isnt a lot of 'science' in color others read that as color doesnt matter - when it clearly does - even if color is more 'art' than 'science'.
  16. Yup, I have this set up. I think it is important to have the motion box as well as the slider because I find the slider itself a bit short to add much 'effect'. The software works well and the app is pretty intuitive - but the price is pretty difficult to justify. I use it and like it mostly for timelapses....
  17. Excellent stuff. Tony really knows how to do clickbait with style.
  18. Typically the older the camera the 'closer' the iso is to the measured iso. As each generation goes by the manufacturers 'cheat' more so the 'improvement' in iso 'looks' better. Take the E-M1 measured iso at 6400 is 3870 - the EM1 ii measured iso at 6400 is 2797!! And look at the big 'shift' in iso of the GH series between GH1 and GH5?
  19. Quite a lot of good information here around your price point. Going for an i7 8700k (or i7 9700k) has the advantage that motherboards are cheaper (relative to x299) and the high clock speed of the individual cores makes it ideal for Photoshop that doesnt benefit much from a high core count (over 4)
  20. Flickr may now turn into a viable alternative. A couple of days ago the announced a revamp... https://www.flickr.com/ ...following on from the acquisition by Smugmug... A 'pro' account is US$49 a year with unlimited uploads. From 'early 2019' video playback will be increased from a maximum of 3 minutes to a maximum of 10 minutes....
  21. Nope the reason was touched upon in Max's video. There is no hard defined definition of ISO. All camera manufacturers 'understate' their ISO. So take a look at this chart from DXOmark for the A7riii... https://www.dxomark.com/Cameras/Sony/A7R-III---Measurements You will see that what 'Sony' calls iso 200, is measured at iso 145 by DXOmark. Why do they do this? Well so people will say - very little noise at iso3200 - partly because the actual iso is 1600. You can go back and look at Canon 5D bodies and you will see the differential between real and Canon's iso has increased with every generation. Why? So that people can say 'at 6400 there is a half stop improvement over the old body' when it is more like a 1/4 of a stop and a 1/4 additional stop iso fudge. When you do a comparison like Max's that uses 'same settings' - shutter speed, f stop, iso - greater amounts of 'iso fudge' end up as 'lower exposure'. As a general rule, smaller sensor cameras tend to 'fudge' their iso more than FF cameras. Take the Olympus EM1 for an example.... https://www.dxomark.com/Cameras/Olympus/OM-D-E-M1-Mark-II---Measurements Iso stated by Olympus is iso200 while DXOmark's measured ISO is 83. So Olympus has fudged the ISO well over 1 stop and almost I stop more than the Sony.
  22. For lowlight, these results are pretty much as expected The A7iii is full frame supersampled from 6k to 4k, the BMPCC is M43 (-2 stops), EOS-R FF sensor heavily cropped (-2 stops), XT-3 APSC (-1 stop) and the Z7 is high resolution sensor with pixel binning (a comparison with a Z6 would be fairer.)
  23. I think the consensus is at +1 for sharpening although some people recommend 0. I would have thought it is sensible to be fairly conservative with in camera sharpening as you can always add sharpening in post but it is more problematic to take away.
  24. Its a good question. We do know that even with usb-c you wont be able to add external storage devices to transfer files - so I am guessing the answer is no. The current ipad pro is kind of frustrating because I cant transfer video files off my Sony even with the sd card reader because the ipad doesnt like Sony's file structure
