    Thad E Ginathom reacted to Pieter in When will Sony upgrade their APS-C sensors with increased megapixels for the a6xxx??   
    ISO-range of A7Riii and A7Riv are the same (100 - 32000), as is the dynamic range:
    https://www.sonyalpharumors.com/sony-a7riv-versus-a7riii-dynamic-range/
    Even though I like the absolute sharpness and detail when I pixel-peep my photo's, it hardly serves a practical purpose. It's like the whole 4k - 6k - 8k discussion in video-world. Yes you'll see the difference if you're sitting at half a meter from your 65" TV, but who does that except the guy who just bought a new TV?
    What would be an interesting concept though is if there was a native 'low-res' mode incorporated in high-res cameras. If enabled, it would still read the full high-res sensor but downsample the RAW-file to a lower resolution. That way you'd still have the ISO-performance of a full-sensor readout but stored in a lower file size RAW if you don't need all this resolution. I might even consider buying such a camera.

    Hi,
    many forums and the "pros" once were certain that the star eater issue makes the Sony A7 Series unusable for astrophotography but I always had good results with my Sony A7rII. So I recently went ahead and had it astromodified. The thick IR-Block Filterglas was replaced with a thin Baader substitute that lets IR Light down to the h-alpha line and the sII line through to the sensor with high transmission. The results can be seen in detail on my google drive link here:
    https://drive.google.com/file/d/1SrdJ7tJbEUwN5KcbXsfpKaesq8KltzmY/view?usp=sharing
    I could write a lot of things that make the A7rII not the perfect camera for astro but suffice to say, it is still bloody capable. Cheers and CS,

Both images have reduced star sizes with a minimum filter applied to masked stars. The masked stars color’s were also tweaked in order to bring them close to the feel of a normal broadband rgb distribution with colors between either aqua and blue or yellow and orange. I did however not manage to create a mask that includes the faintest and smallest of stars. If you look closely you see how the star colors are a little off, the smaller the stars get

    Thad E Ginathom got a reaction from Benz3ne in I have so many questions it's not funny.   
    Takes me back fifty years to student days. We got into this habit: one of us would start on some topic we knew little about, we'd flounder around for a few minutes, and end up chorusing, "Buy a book on it!" And hey, very often we did.
    Those days, there was no internet, no google and no youtube. That was great for the book trade! Have to say, though, that with a new, complex camera, my first instinct is still to get the book. An actual, printed book.
    I consider it a shame that they don't come with printed manuals any longer. Well, the manual is online, and it certainly should be one of our resources, but it is a dry thing indeed: a set of short technical descriptions with very little about how or why we might want to use (or not use) a setting or function. The books come with added personal experience and advice. Well worth having.
    Second to that (well, equal, in a way, just a different way) is the wonders of youtube. There will be reviews and tutorials for your camera. Watch several: get different viewpoints on the same stuff. Even watch elementary, beginners stuff about your new camera!
    Third, for personal contact and specific questions, online forums are hard to beat. But no-one can take you through the whole thing, like a book can, or go deeply into one aspect like a youtube video can.

    Thad E Ginathom got a reaction from mlevin77 in Possible to power camera via charge port?   
    No, it is not possible. The a6000 does not have that feature.
    And for the cameras that do... Please note that it is not quite as simple as powering the camera from the USB port. What happens is that the battery powers the camera, and the USB power charges the battery. This means that there must be power in the battery, and it will run down while the camera is being used, just... slower than without the USB power attached.
    For true external power you need the dummy-battery device for all these cameras.

    Move Exposure modes PASM
    I don't do video, but I remember seeing this, and dug out my a6000 to check that it is true for this model...
    In Video mode (video-film symbol on the mode dial) you can change P-A-S-M:
    Menu: Camera-symbol -> p6 -> item "Movie"
    Function Menu set: Assign one place to item "Shoot Mode." This would be the easiest regular-access method
    Either of these bring up an on-screen display from which you chose your desired exposure mode.
    It is not, as far as I could see, assignable to a customisable button. It isn't on my a6500 either.

    Good. The bigger question is why they would think anyone wants sounds like that anyway!
    Because they actually have nothing to do with each other. Silent Shooting only turns off the mechanical shutter and and turns on the electronic-only system... for stills. It is true though, that your camera isn't very silent if it beeps whenever it focuses.
    Power-save certainly works for stills. Maybe it's different for movies. And, also, there are differences between movies in movie mode (on the dial) and just pressing the red button any time (which I actually disable: it is too easy to press by accident).

    a6500: Same menu setting, same beep. Covers, as far as I know, all "control" sounds made by the camera.
    Having just checked that (mine is always "off" from day one) I can understand how annoying that beep, bidaly-beep movie start/stop noise would be.
    I'm expecting  that identical-feature menu settings on different models will be much the same...

    Thanks for all the help! I think I’m good now. Cleaning the sensor seems to have fixed everything. The finder/monitor was set on Auto. I switched it to monitor (manual) and the screen displayed normally. But when I switched back to auto, only viewfinder worked. Cleaning the sensor (which I didn’t even realize was there and controlled this- I swear this camera makes me feel like my IQ drop 30 points) and it’s acting normally. Thanks again!

    Thad E Ginathom got a reaction from PSikes in power from AC, using cam for streaming   
    My guess... it'll be like the a6500, which says you have to have charge in your battery while USN-"powering" and that the battery will be running down. Explanation: the USB is not actually powering the camera, it's charging the battery which is powering the camera. You're going to get enhanced runtime, but not forever. For that, you need the dummy.

    Thad E Ginathom reacted to Benz3ne in Shwmae pawb - Hi all!   
    Firstly, diolch! That's 'thank you' for having me on this forum. From Wales (next to England) and with an A7iii en route, which should arrive safely tomorrow.
    Have previously been involved with the Pentax community over the past two years, shooting most recently with the Pentax K1, and will continue to be involved there with my small selection of vintage Pentax/PK mount and M42 lenses. With that said, I thought it prudent to join in here so any questions/queries can be succinctly answered by you knowledgeable folk!
    I should also have a Samyang 45mm f/1.8 AF on its way to me before long too, following a trade with a UK stockist! Looking forward to seeing how much focus peaking/magnification aids me with the manual lenses, as well as trying my hand at video (I've managed to give a Kiron 28mm f/2 a clickless aperture so that'll be fun!).
    Lastly, is it just me or is it relatively quiet here? I've seen a huge amount of interaction in the Pentax forums but it seems a bit more sporadic here (just an observation, not a criticism)!

    After being cooped up all winter with nasty weather and Covid 19 shutdown in New York, it felt really good to get out hiking and taking photos. This was my first photo of the season. I didn't expect to take any photos so I left the A7RIV home and just took the A6500. The swan was on the far side of the pond.

    My problem is solved. It was very simple. The shifting did not work as I use back button focus. Switching focus to the shutter button allowed  focus bracketing to work as it should.

    Thad E Ginathom reacted to Pieter in I am looking for the best portrait lens for my a6000   
    Bear in mind there's also a 35mm f/1.8 lens with stabilization specifically designed for APS-C cameras, make sure to have a look at that one: it's about half the price of the fullframe version.
    That being said: you mention you're looking for a portraiture lens and are considering 35mm focal length. On APS-C cameras, 50-60mm is generally considered to be the ideal focal length for portraiture. Don't go blindly on this as your portraiture style might include more context around the subject, but for an a6000 camera I'd say the 50mm f/1.8 OSS or Sigma 56mm f/1.4 would be ideal portraiture lenses.
    Honestly, unless you're planning to go fullframe one day, the combination of a 'professional' fullframe lens on an a6000 camera doesn't make too much sense to me. You're paying a lot for a bigger lens to cover a sensor area you're not utilizing.
