Readers have pointed out some artefacts:
- Jaggies in some images
- Black dot artefacts in some images
I have looked into the issues and found that the jaggies were caused by demosaic artefacts in Lightroom combined with strong sharpening. I therefore reprocessed the comparison with MFD images using RawTherapee with default sharpening. Default sharpeing in RT may be regarded weak, but it applies similarly to both images.
The black dots artefacts were caused by mainly by me using the local adjustment brush in LR with automasking to lighten up the chapell against the background. In this case I used the radial filter instead giving a similar effect, that made the black dot artefacts go away.
The images affected by this observations have been (hopefully) updated.
I recently bought a Sony A7rII and this is my experience with that system
What did I buy?
- A7rII Body
- Sony 90/2.8G Macro
- Canon 24/3.5 TSE LII
- Metabones MB-EF-E-BT4 adapter
- Sony LA-EA3 adpter for A-mount lenses
- Getting rid of the mirror
- Being able to use Canon TSE lenses
- Being able to use almost any lens
- More than 24 MP resolution
- Grass is always greener on the other side of the fence
Why didn't I buy the original A7r?
Why did I buy the A7rII?
What I don't like with the A7rII?
- Image stabilisation and AF should be overriden by presets. I want a preset for shooting on tripod and that should disable both image stabilisation and AF.
- Battery is to small. Use the same batteries as the Alpha 99!
- Please add an option to toggle peaking and zebras.
- Zebras optimized for movies. Zebra should indicate real world clipping when shooting stills
- Please give us a nice standard zoom with excellent sharpness
- Please give us 12.5X magnification in focusing assistance
Initial shooting experience
- Original Metabones adapter is broken. doesn't connect to camera. Newer adapter may work -- no observations to the contrary
- Most lenses work reasonably well
- AF with A-mount lenses is accurate, but somewhat slow
- AF with original Sony E-mount lenses very god
- Tendency to overexpose
Extended shooting experience
- Sigma 10/2.8 APS-C fisheye
- Sigma 12-24/4.5-5.6 zoom
- Canon 24/3.5 TSE LII
- Sony 24-70/2.8 ZA zoom (that has been subject to fall)
- Sony 70-300/4.5-5.6G
- Sony 70-400/4-5.6G
- Sony 28-70/3.5-5.6 (kit lens)
- Sony 90/2.8 G Macro

On the other hand the upperside left crop below is really bad:

Findings on the lens front
Using the A7rII with Canon lenses
One of my main interest with the A7rII was to be able to use Canon's T&S lenses. I bought a Metabones Mark IV adapter and a 24/3.5 TSE LII to be used with the Sony A7rII. My first Metabones quickly developed some unreliability, failing to connect with the camera most of the time. I bought a later version called Mark IVT of the Metabones and that worked mstly with just a few hang ups.
Metabones is working on new firmware releases for the A7rII so some or most of those issues may be resolved.
With the second Metabones I had little problems.
The 24/3.5 TSE LII I have is someowhat limited in sharpness compared to the Sony 24-70/2.8 zoom at 24 mm. May be the sample I have is not that good. I have been shooting quite some architecture kind stuff and the 24/3.5 worked very well on that kind of subjects. Focusing is OK, but could use a bit more focusing throw.
I also had the opportunity to shoot Hans Kruse's 24-70/2.8 and his 100-400/4.5-5.6 zoom on the Metabones. Both lenses worked well, except AF being unusable beyond 200 mm on the 100-400/4.5-5.6 zoom. What happens on the 100-400 at 200 mm is that the lens starts a slow hunt for focus. Once it gets close to optimal focus it snaps into focus. The Sony 70-400/4-5.6G did not have a similar issue.
The Canon 24-70/2.8 LII is a very attractive lens and I may ending up buying it. It is a much nicer design than the Sony 24-70/2.8ZA.
Can the Sony replace the Hasselblad?
