    Maccam got a reaction from Kisaha in Aperture 600d Pro light vs Sachtler Flowtech Tripod w/FSB-4 head   
    Sorry for slow reply. Thanks everyone for their comments/thoughts. Much Appreciate.
    I went with the Flowtech and absolutely love it. Total next level. ✌️

    Aside from F mount, you can adapt PL, M42, Contax C/Y, Canon FD, Minolta MD, Leica R amongst others.
    The only ones that you are excluded from is Leica M, Sony E, L mount and of course m43.

    Maccam got a reaction from Emanuel in Moment Air: Anamorphic Lens for Mavic 2 Pro   
    Didn't seeing any post yet here on the Moment Air lens. Wanted to maybe get a discussion going about it. Link to it kickstarter below. Essentially Its a Anamorphic lens adapter for the DJI Mavic 2 Pro. Its got me very interested. Wasn't too impressed with the color grading in their promotion video but I could see the potential. Love to here everybody's thoughts here.

    Maccam reacted to noone in Opinion - DXOMark's camera scoring makes ZERO sense!   
    DXO has their explanations.

    Low light score in particular is an actual ISO and I think the easiest to explain.
    "Sports & action photography: Low-Light ISO
    Unlike the two previous scenarios in which light is either generous (studio) or stability is assured (landscape), photojournalists and action photographers often struggle with low available light and high motion. Achieving usable image quality is often difficult when pushing ISO.
    When shooting a moving scene such as a sports event, action photographers’ primary objective is to freeze the motion, giving priority to short exposure time. To compensate for the lack of exposure, they have to increase the ISO setting, which means the SNR will decrease. How far can they go while keeping decent quality? Our low-light ISO metric will tell them.
    The SNR indicates how much noise is present in an image compared to the actual information (signal). The higher the SNR value, the better the image looks, because details aren't drowned by noise. SNR strength is given in dB, which is a logarithmic scale: an increase of 6 dB corresponds to doubling the SNR, which equates to half the noise for the same signal.
    An SNR value of 30dB means excellent image quality. Thus low-light ISO is the highest ISO setting for a camera that allows it to achieve an SNR of 30dB while keeping a good dynamic range of 9 EVs and a color depth of 18bits.
    A difference in low-light ISO of 25% represents 1/3 EV and is only slightly noticeable.
    As cameras improve, low-light ISO will continuously increase, making this scale open."
     
    It has nothing to do with AF etc so I think the sports scores are pretty reasonable maybe more so if you just consider them as low light rather than sports and remember it is based on their criteria.       I am fine with using an A7s for night time sports.      I use an old manual focus 300 2.8 anyway so it just means I can use a higher shutter speed.     None of the shots would be printed huge so 12mp is fine.
    A modern FF DSLR would be a better sports CAMERA most of the time but does it have a better sports SENSOR (given DXOmarks criteria)?
    The overall scores are a bit based on voodoo as the bits that go into that are subjective without full explanation as to weighting.
    I think some of the anomalies might be because of a low number of samples tested given many cameras get slightly different scores with the same sensors.      A slight difference might be just enough to take a camera a bit over or a bit under their marks.     I don't think the A7s is any noisier than the A7sii and It seems the colour depth might be why the A7sii gets a lower score for low light (the point they cross 18 bits for colour sensitivity).
    For video it is all a bit silly though as they are only testing RAW stills and most video is Jpeg.
    I would love to see a site test sensors for video.    RAW and otherwise.

    Maccam got a reaction from tusoli5 in Time to step up - Panasonic GH5 must go 6K Super 35mm to compete in 2016   
    The low light high ISO performance could be improved with better S/N firmware even with M/43. Why do you think the Nikon D810 iso improved so much over the D800 or even the 12mp D700. Now the D810 does not have the exact pixel density as the GH4, but this still applies.
    But with all that sound I agree I would rather have a super 35mm or full frame image.
    I would really like to see a color space improvement. Nikon has a beautiful color space. Improving color should not only be on Panasonic's to do list, but Sony's as well.
    If not then just gives us RAW and go home.
