    DrJohn reacted to CathyF in BIF wing movement aberration   
    I have a problem with shooting birds where there is wing movement. Its difficult to explain what's happening so please have a look at the attached images.
    I have two Sony A7iii bodies and it is the same with both. I have had the same problem with both the 70-200 and 200-600. I've tried turning OSS off on the lens. These were both taken using a tripod. They were taken with shutter speeds in excess of 1/1000. I would expect motion blur in the wing tips but certainly not what I am getting. 
    I contacted Sony who suggested I update the firmware but it is still happening.
    Has anyone come across this or got any suggestions on what else to try?

    DrJohn got a reaction from Makeev in The First Wild Life photo of the season - Swan   
    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.

    Thanks Chrissie for your information.
    I've been doing wildlife for a long time, but not birds in flight. I have spent many many hours waiting for a shot that never happened.
    I currently have the A7RIV and the Sony 100-400 mm with 1.4x and 2.0x teleconverters. I'm also considering the new Sony 200-600 mm. Both lenses and camera have OSS.
    I live near the water. So. Seagulls are easy to find. They even fly over my house. And, for some reason I really like seagulls.

    I was out last night with my A6500 camera and 70-350 mm lens. The focal length was too short for lunar photography. It was what I had on hand and so I took the shot anyway. You can enlarge this photo 200-300% without it degrading too much. I reduced size for the internet. The Sony cameras and lenses are really great.

    In addition to the photographic merit, of course: as a biker, I like the way how this bird is doing a curved flight, yet keeping his head perfectly aligned with the horizon.
    Pretty much like motorcyclists do it, too.

    A follow up just because
     I purchased both the Tamron and the Sigma with the intent to test both side by side, then returning the loser. In the end however it just wasn’t that easy. Two outstanding lenses.  Outstanding. There is no loser. I’m not, by nature, a pixel peeper except when I’m testing stuff for purchase and I did some here but more just looking at photos in Lightroom with little or no adjustments. Kinda of just how the photos felt (if that makes sense)
     
    I’ve never been too terribly concerned with weight (within reason) but I must admit the Tamron’s feather weight was more enticing than I would have thought. Especially having both out and about in the field for a real world comparative test. It’s just a treat to have that good of a lens that really feels like it’s not even on the camera. Without diving too deep into peeping, if I had to review my results comparing the two lenses between 17-24 (focal points both cameras share) I’d say the only difference I noticed was of a color profile. Despite The conclusions of a couple of comparative reviews on YouTube in which the results were, the Sigma was warmer, I disagree. I love the look of the Tamron.
    The Tamron focused a touch quicker but the differences were so small as to simply not be an issue. I’m an occasional “Manual focus” guy so the Tamron lost points there against ease of a MF/AF button on the Sigma.
    The Tamron scores big, big points (at least for me) for its filter threading capabilities. It lets me use my existing filters and also affords me tons of expansion filter choices. That and it’s such a light, small lens the difference between a screw on filter on a light lens against a heavier lens with an even bulkier filter kit is pretty considerable.
    In the end however (at least for me) it really only comes down to focal length. Both lenses IQ are simply amazing. Amazing. The difference however between 14mm and 17mm for my style of photography was just too much to ignore. It’s kinda massive.
    If you don’t need 14mm the Tamron wins and considering the price vs IQ,  pretty handily. If you need that IQ quality down to 14mm the Sigma is equally as stunning but at a much higher cost of entry and a more difficult filter scheme.
    I bought the Sigma.

    I can testify from experience (albeit not for Astro) the Sigma 14-24 f/2.8 is truly a remarkable lens. You will absolutely not be disappointed!
