I would like to see more content focused on teaching the nuances of video shooting to photographers. I like Jordan's reviews but the content seems to be focused on experienced video shooters and much of the jargon is lost to me.

Glenn Barber: Sony software sometimes seems so well conceived and poorly executed. My A1 footage processed through Catalyst did not come out as well as just selecting stabilization in iMovie.

FlyingDoc - I will definitely give Catalyst another try - the 8Bit issue was another reason I didnt really connsider it. My handheld footage with the 200-600 is territble without stabilization - although with IS off - in-camera it night look even worse. One would think that Catalyst might warn if it sees footage with Active Stabilization used during recording that is being re-stabilized during processing.

FlyinDoc: Very helpfull - shooting 60P at 1/250th or 1/500th - then slowing to 50% for Birds in Flight.
Are you saying that if I turn on Active Steady Shot stabilization in the A1 (as recommended by Sony and others) that the Catalyst processing doesnt work?? Possibly my Issue?

I just purchased this lens and have been checking it out. I typically shoot in Raw and my older Photoshop Raw didnt have the corrections for this lens - so looking at my first test shots in uncorrected raw - I was floored by the extreme corner vignetting at f4 and f5.6 at 16mm - it seems like 3-4 stops. Updating my PS and applying the corrections - these corners disappear with the distortion correction applied and then the vignetting correction gets most of the rest - although you still seem some image quality reduction in the corners.

My question is - when you review these kinds of lenses that are designed with Digital Correction - are the images and test shots always corrected digitally?

On article DPReview TV: Sony Alpha cameras - The good and the bad (425 comments in total)

Come on guys - usually I like your reviews - but this was about as irrelevant as it gets when it comes to wants and needs

If you spent any time in the Sony Forums there were plenty of wish list items that users have been posting about for years

1. Better support for consumers - and the ability for prosumers to get pro support like you can with Canon - based on your equipment

2. Sony Software needs a huge overhaul. Faster support of bugs with new releases - some of us waited over a year for a reported bug in custom shoot sets on the A1 that was critical for Wildlife shooters. One of the most common complaints is the firmware updates - some in the forum have wondered how small their software team must be to take so long to fix things and why the UI is so bad.

3. Other features like focus stacking - grip further from lens mount, IBIS ....

Please - spend some time reading through the forum history before you waste time with softballs.

Glenn Barber: I would wait on this one. I hope it doesn't come with all the display bugs that came with the Macbook Pro M1 Max. There are scores of problems being reported with bizarre display issues and external monitor bugs. I called apple about the screen sliding to the right on any full screen open, then quickly bouncing back. When attempting to slide back to the app, the screen resists your effect and snaps back the moment you lift you hand from the touchpad or the back of the magic mouse - its incredibly maddening that it was released with this behavior. Support acknowledged that it was a known issue and being worked on.

My son has the M1Pro and doesnt have issues - but for some reason the M1ProMax does... Really hard to work with when I open full screen apps.
If you search the web there are reviewers who have a variety of examples of strange behaviors.

Most pros or semi-pro's would consider availability of current lenses a major deciding point in weighing one flagship against another. This alone would move the A1 up in the ranking.

Wait - don't the optical formulas for DOF resolve to physical aperture size - period. not aperture ratios, or focal length I discovered this when doing 4x5 and researching the optics. Bigger formats require larger apertures for the same aperture ratio.

Don't need an off-camera recorder, but this was of the funniest best done reviews Ive seen...

I ran into some surprising misbehaviors with my A1 where the custom shoot set setting for exposure compensation in Shutter preferred with Auto ISO would not work properly or consistently in the initial release or in the first firmware update. These behaviors were never an issue with any other FF Alpha camera. I notice now some other strange behaviors being reported - like IS not activating. For me it was a huge disappointment because I could not shoot with settings like those on my A7R4 and A9. Almost seems like this camera had so many new features there wasn't enough focused testing on on legacy behaviors.

Glenn Barber: I can't really see much discernable difference between the A1 and A7R4 at typical ISO's and about the same level of noise (unfortunately) - where there is much more visible difference with the A1 and Canon R5 or Nikon Z7 II

Does anyone else see something Im missing - doesnt look like a lot of improvement over the A7R4 - but then its nearly as good. However it does look noisier than the A7R3. I was hoping to see a more visible noise improvement at 1600 or 3200 ISO

As I already have a A9 and A7R4, I was looking for a camera that might cross the line and cover both well. While I can see that image quality of the A1 is very close to the A7R4 - I was hoping for a bit more noise reduction in background darker areas - a bit like the A7R3 had. I am waiting to see the dynamic range testing where they push shadows.

I typically look at the fine detail in the clothing on the beatles and in the feathers as well as on the currency. Also I pay attention to the noise in the darker areas as ISO is raised. Doing Bird photography with extreme crops with the A7R4 - often having to shoot at 1600 or faster and pushing shadows I am a bit more critical than most. So as I said not much difference to my eye on the A1 and A7R4 - a little more difference comparing the A1 to the Canon and Nikon

Does this camera have an AA filter - how strong? As a A7R4 users I am hoping not...

D_Surrey: Just a couple of things to note: the Mavic 2 Pro doesn't/can't rotate the camera to portrait mode which was handy for panos etc. Also it lacks 4k cinema resolution. No biggie for me personally but no doubt gonna be a problem for some people.

FYI - PolarPro has circular polarizers for M2P - they snap on with a quarter turn to replace the squarish clear filter on the pro which is similarly removeable.

D500 001: Nice feature for sure. Would like to see a hand triggered model.

Hand squeeze makes more sense... Assuming you are walking around with the monopod collapsed as I do - what you want is it to drop to the ground and you firm it to that position with a squeeze. Im not buying a $500 foot pump to lock a monopod into position.

Glenn Barber: My biggest concern is how this mirrorless focuses with Longer lenses 300mm. I have a A7 and A7R and neither focuses quickly with adapted long lenses. If this is to be a sports and wildlife camera - focus acquisition with long lenses is critical.

Mistake here I have an A7r & A7rII - so usually it focuses wel with native and adapted lenses however nothing near 300 mm focuses worth a damn.

Its. Promising to hear Rishi's feedback - but I'd say I'd like the reviews to cover more details like this.
