Sony a7R IV Underwater Camera Review by Backscatter: “hands-down best stills image quality”

Backscatter tested the underwater performance of the Sony A7rIV and concluded:

The Sony a7R IV is a massive leap forward in image quality. With 61MP of resolution, it will produce big prints with tons of sharp detail like no other camera before it. Cropping a vertical from a horizontal is not a problem and will still yield more resolution than most other cameras at full frame. The color of the still images look great right out of the camera, and the dynamic range is among the best of any camera. With both image quality and resolution, you can have your cake and eat it too.

10 frames per second continuous shooting with this much resolution is crazy good performance. 10 FPS used to be reserved for sports cameras with much lower resolution, but now this camera can push those boundaries and shoot fast action. This being said, it is a little clunky to shoot fast and review, requiring extra taps of the playback and shutter buttons to switch back and forth from shooting to image review, but this is something common to all mirrorless cameras. In this area a SLR is still king.

The Real-time Tracking AF is a major leap forward in autofocus for Sony. It can now compete with the likes of the Nikon D850 for that top autofocus performance slot. In our testing however the macro autofocus capabilities of the Nikon D850 still outperform the Sony a7R IV, but you can get closer with the Sony a7R IV than ever before to the Nikon macro performance if a Canon macro lens with an adapter is used.

We wish Sony would develop a proper fisheye lens and a better performing macro lens, but thankfully there is a good solution with using an adapter for some Canon glass, even if it adds a little bulk and isn’t as streamlined as native glass.

For video shooters, whether this camera fits their needs will depend on the type of shooting they do. It’s disappointing to not see any 4K/60p from Sony yet. Canon and Panasonic both have full-frame cameras now that are shooting over 4K resolution at 60p. That coupled with the rather shallow limitations of the custom white balance, make this camera a choice for more casual video shooters whose real main interest is photo.

If you’re looking for the hands-down best stills image quality and biggest resolution, there is no other place to look than the Sony a7R IV.

Sony A9II sensor tested by DxOmark: “high sensor performance for a lower price”

DxO tested the A9II and concluded:

Sony says that the a9 II has the same sensor as the original a9, but as we’ve seen the new model adopts a different approach to processing, using a change in sensitivity behavior both to improve color discrimination and to widen dynamic range at higher ISOs. It’s the first time we’ve seen this and it marks a shift in strategy for Sony.

The Sony a9 II is certainly a niche camera, built to compete alongside the Canon EOS-1 DX Mark II and Nikon D5. However, while it’s unlikely that individual photographers or agencies would switch from those rival cameras, bearing in mind their investment in lenses, the Sony a9 II’s high sensor performance and lower price would be tempting for newcomers thinking of entering the competitive field of sports journalism.

New Tamron 70-180mm images and size comparison with the 28-75mm lens

Sara from Tamron shared those four images of the new 70-180mm f/2.8 FE lens. On top you see the size comparison with the 17-28mm f/2.8 FE and the 28-75mm f/2.8 FE. Some more info:

– The new lens has an improved AF motor from their already fast rxd motor found on the 28-75mm FE.
– As you can see from the photo below the new zoom extends for about 2 inches

 

This is lens with a big “I want it” factor :)

Matt Granger: Sony Lenses – What to buy first?

‘Sony Lenses – What to buy first?’

When you buy into a new camera system – what lenses should you first buy? Whats the best way to decide?

This is an issue that Photographer Matt Granger is facing now – having recently bought an A7R4 for his travel and portraiture work.

In this video Matt talks about how the awesome Sony eye autofocus let him catch shots he may otherwise have missed, and why he decided to finally buy it.

The process he uses to work out the lenses to buy is pretty smart, watch the video below to see for yourself.

You might be surprised but several of the lenses Matt lists are not Sony G Master lenses. In fact there are some off brand options in there – as he explains, value for money is important for everyone – especially if it is your business. (Reminder Matt is raising money for charity as part of a Business Deal that ends tomorrow. You get $2100 of materials for $89! Check it out at https://geni.us/OwnBoss )

The five lenses Matt plans to get are:
24mm f1.4 G Master
55mm f1.8 Sony Zeiss
85mm Batis
70-180 Tamron
135 G Master

What do you think? If you were starting from scratch – what would your first 5 lenses be?
