Sony a7RIV Review for Wildlife Photographers
By Aaron Baggenstos

Introduction:

I recently spent a month in East Africa leading photo safaris where I had the opportunity to field test Sony’s latest high megapixel a7RIV paired with a variety of their new super-telephoto lenses.  In particular I evaluated the camera and lenses (600mm f4, 200-600mm, 100-400mm) on the features most important for wildlife photographers.

Unlike several other genres of photography, portrait, wedding, and still life for example, where mirrorless cameras have had the performance and lens selection, they demand for quite some time, professional wildlife photographers have been waiting for a full frame, fast focusing, mirrorless cameras with native mount super-telephoto lenses.

Sony delivered big for us with the announcement of their flagship a9 (now a9II) which I reviewed with great optimism last year in Alaska (click here if you missed that review).  But the longest lens available at the time was a 100-400mm.

Excitingly, in October I received one of the first copies of a squeaky new Sony 600mm f4.  After testing it extensively I can confirm that it is a truly remarkable lens as well as the lightest one on the market.  Mounted to an a7RIV my setup is 3.5 lbs. lighter than my DLSR equivalent with a grip which equals much appreciated weight savings for my international schedule.  My back won’t complain either as I hand hold the big telephotos quite a bit.  I enjoyed some of the new features of the 600mm f4 including a full time

DMF setting, which turns off the manual focus for when panning off a bean bag, and a new focus ring for fine-tuned manual focus.
Now with a variety of high preforming super-telephotos, and the addition of the a7RIV to their lineup for me Sony has set a new standard for wildlife photographers and the new technology that will lead us into the future.

Watch the Review:

a7RIV Camera Highlights:
– The 61MP sensor delivers some of the most stunningly detailed images I have ever seen.
– An innovative autofocus system with subject tracking and animal AF fast enough to track birds and wildlife.
– Pair it with one of over 50 native lenses (no adapter needed) including a spectacular new lightest on the market 600mm f4, 400mm 2.8, 200-600mm, or 100-400mm.
– Exceptional low light performance.  I’m very happy with files up to ISO3200 and comfortable pushing to ISO6400 when needed.  ISO12800 is usable.
– Brilliant OLED EFV viewfinder with live histogram, the first one I have looked at that I consider superior to the optical experience of a DSLR.
– 5.5 stops of in body stabilization.  Although still not as good as Panasonic or Olympus.
– Excellent battery life, no issues here.
– Charge your camera with a USB-C cord, save carrying a bulky battery charger.

a7RIV Limitations:
– You’ll need higher shutter speeds in general with the higher MP’s, I noticed at least a stop difference over my D850, plan at least two stops over a D5.
– It’s still not possible to move the focus points or access some of the key menu items while buffering.
– The uncompressed RAW files can be a massive 120MB, so you’ll want fast SD cards, and an upgraded laptop with SSD.
– EVF blackout significant while shooting uncompressed RAW, much less while using APSC crop or on continuous high +.  Use this setting for birds in flight or action.  The files still look great.
– The silent electronic shutter suffers from bad rolling shutter.  Shoot mostly with the mechanical shutter.  I actually missed my shutter click sounds when I turned it off anyway.
– Like all mirrorless cameras the sensor attracts a bit of dust so make sure to carry a sensor cleaning kit with you into the field or be prepared to remove spots in post.

The a7RIV allows you to print your images big with a new level of detail.  Check out my Mountain Gorillas 40x60in and Baby Elephant 20x30in.  Both stunning to look at in person.

Disclosure:
– The opinions in this review are my own and not persuaded by anyone or any company.  I did not receive payment from Sony to make this review.
– Although I’m a member of Sony Pro Services I did purchase the camera equipment for this review with my own money from Allen’s Camera my go to source for camera equipment.
– For many years I’ve field tested a wide variety of cameras for Nikon, Olympus, Sony, and others.  I generally select these cameras based on their merits for the images I am trying to make.
– I use the camera equipment I personally enjoy and often trade my cameras in for the latest and greatest, just my personal philosophy.  This helps me with articles and teaching clients showing up with a wide variety of cameras on tours and workshops.
– Always remember, it’s the photographer and not the camera that creates an image, and “a good image is a good image” regardless of what camera produced it.

I hope you enjoyed this review as much as I did making it. I would love to hear your comments/questions below.  Happy holidays everyone and I’ll see you on the next adventure.

DPReview TV: Tamron 35mm F2.8 ($349) vs Sony/Zeiss 35mm F2.8 ($800)

Chris and Jordan tested the new Tamron 35mm f/2.8 FE lens and they really like the lens optical performance (less so the AF performance).

Also Marc Alhadeff likes the new lens:

The Tamron 35mm F2.8 Di III OSD M 1:2 (450 euros) is an excellent lens for its price
It is part a set of new Prime lenses with all a short focusing distance , a 1:2 magnification ratio, a F2.8 aperture, same length, same weight
In term of sharpness it competes with the best : Sony FE 35mm F1.8 (700 euros) & the Sigma 35mm F1.2 DG DN Art (1500 euros)
Its sharpness is mostly excellent/outstanding on the Sony A7RIV and the results in term of color rendition / background blur are very good

Tamron 24mm FE review by Marc Alhadeff: “outstanding lens for its price”

Marc Alhadeff tested the brand new Tamron 24mm f/2.8 FE lens. I know that on paper the specs are a bit boring. But the performance is excellent! Here is Marc’s conclusion:

The Tamron 24mm F2.8 Di III OSD M 1:2 (450 euros) is an outstanding lens for its price. It is part a set of new Prime lenses with all a short focusing distance , a 1:2 magnification ratio, a F2.8 aperture, same length, same weight. It delivers very similar results to the Sony 24mm F1.4 GM (1600 euros) for a fraction of the price although obviously only being a F2.8. Its sharpness is mostly outstanding on the Sony A7RIV and the results in term of color rendition / background blur are excellent

Pros

Outstanding sharpness across the whole frame on A7RIV
Very compact and light : discrete and going well for video on a Gimbal
Low price
Very good background blur and color rendition
Good resistance to flare
Very short focusing distance allowing to reach 1:2 magnification
Fast and reliable AF

Average

Good build quality (but much lower than GM)
Vignetting is moderate (to be corrected in a future Lightroom Lens profile)
Moderate chromatic aberrations
The Bokeh Balls show 7 sided shaped polygons as of F4 and no more a ball like at F2.8

Cons

Lot of distorsion (to be corrected in a future Lightroom Lens profile)
Noisy AF in Video
Only F2.8

Unless you need a faster lens than a F2.8 , the Tamron is an absolute must have and a bargain for a A7RIV or A7RIII for still photography. If you shoot mostly video the small size of the Tamron will be a key plus on a Gimbal but you should avoid to record audio in the body in silent environment as the lens is quite noisy. If you only have a A7III with only 24Mpix and have already the Tamron 17-28mm F2.8 you won’t see a lot the difference in sharpness

First image of the new Tamron 70-180mm f/2.8 FE lens mounted on the Sony A7III

Digitalcamera.jp shared the first image of the new Tamron 70-180mm f/2.8 FE lens mounted on the Sony A7III. Here is the google translated text of their first impression:

-With a development announcement, the 70-180mmF2.8 is extremely compact, although it will be released next spring.
-If you look at the actual machine, it is compact enough not to think of F2.8. It feels even smaller than Canon’s “RF70-200mmF2.8L”.
-Weighs in the 800g range, this size makes it feel like you can easily carry it around.
-Furthermore, AF speed is quite high, so it seems to be useful for shooting moving objects. It ’s a very fun lens.

Here are also the images of the three new f/2.8 primes:

The 20mm f/2.8 will be released in January!
