lens – Sony a7 III vs a7R III + Lenses

I currently own the A7 III, the Tamron 28-75 2.8 and the Sony 85 1.8 which is the focus of your question.

Camera

The decision between the a7 model and the a7r model is that it must first take:
The two cameras share many features, but there is more difference than the simple resolution.

Benefits of the A7 III

  • Slightly better performance in low light due to larger pixels
  • Better AF point coverage and generally slightly more modern AF system
  • Best suited for video as it doesn't use pixel binning and uses full format

** Benefits of the a7r III
– Better resolution (a plus for product photos) and optional pixel shift
– Better resolution of the viewfinder and rear monitor (this is really noticeable, you can hardly judge the sharpness on the A7 III)
– You can use the APS-C mode and always have sufficient resolution to use the shooting.

So you have traits that speak for each model. The A7R seems to be the best choice if you tend to shoot still, while the A7 is clearly the best choice for video.

glasses

The Sony 24-105mm f / 4 is a magnificent lens, but as you have already discovered, the limitation lies in the aperture. If you plan on getting the 85mm and the 28-75mm, that doesn't add much to the mix.

Sony 85mm

This lens is just great – especially for the price. It is razor sharp, light, ok bokeh, super fast AF, good build quality. You can't go wrong with this one.

Tamron 28-75mm

Another very good goal. The cheap price is ridiculous for what you get: Very good sharpness across the range, fast AF, ok for video, light, good build quality. The downsides are the limit at 28 instead of 24mm on the short end and the poor bokeh, when you shoot wide open. Always the best lens in this range for the price. And the closest focusing distance to this lens is so small that you can literally fall on your subject. Which is really cool.

Note: There is a new Sigma which is also supposed to be very good. But as with all Sigmas – it will be heavy.

Personal thought

I would suggest buying the Tamron and the Sony 85mm. If you can only afford one goal, choose the Tamron first. 75mm at 2.8 is also a decent focal length for portraits. The 85mm will provide better bokeh and better sharpness, but is less flexible.

Then, as a secondary step, I would assess what you missed the most in your first shots, and then invest in a larger lens or a 70-200 2.8 (Tamron plans a 75-180 mm 2.8 in spring 2020) to expand your options.

Raw therapist lens / geometry correction Sony A6100

I recently bought my first "real" camera, a Sony Alpha 6100 (Sony ILCE-6100).
I choose that both, .jpg and .arw must be kept.
When I compare the .jpg and the .arw imagine that the geometry is a little different.
Straight lines in the .jpg the file looks slightly curved in the .arw file.
Therefore, I have tried to process some of the raw images using RawTherapee 5.8 to resolve this issue, but I have failed.

When i click on Transform tool and go to Lens / Geometry I tried to fix it using the Profiled Lens Correction. By default, Automatic (Lensfun) is selected which does not really help.
I tried to change it to Manually but I can't find the Sony ILCE-6100 camera, nor the lens in the OSS 3.5-5.6 / 16-50 kit that I use. There is also the option to import an LCP file but I couldn't find it and I have no idea what it is and where I can find it.

What is the best way to correct geometry using RawTherapee?

(I hope I have understood the English terminology well, I use RawTherapee with a different language and so I don't know what it is called exactly in English. Let me know if you're having trouble follow my descriptions.)

sony – How does the iPhone make long time slow motion videos?

I recently started researching slow motion video recording. I am considering buying Sony RX100 VII or Sony RX 10 IV.

What I have found is that by including the two cameras above, even many high specification cameras can only record a few seconds (2 to 7 seconds) of HD in 240 frames per second.

And I understand the theory behind the size of the buffer, the number of images taken in high quality, processing and saving the video to be played back at 30 fps requires a buffer size and processing power.

But my iPhone XR can record Slo-Mo videos at 1080p 240fps as long as I want. I tried for at least 30 seconds and it kept recording, even after 30 seconds I stopped, otherwise it would have continued.

So how does the iPhone work? And then is it worth it to buy these high end cameras if all I'm interested in is slow motion video.

Nikon D7500 vs Sony A7II

I want to buy a camara for less than 1000 €, my favorite is the Nikon D7500 and Sony A7II, which camera is better for portrair and astrophotography?
If you know better cameras for less than 1000 € (or a little more) tell me, thank you

sony xperia – Will a hard reset remove malware / viruses / malware from my Experia X?

I suspect my phone is compromised and if a simple hard reset resolves any potential issues, I will do so. Will this solve all potential problems? I'm afraid the guy who just replaced my phone screen (had my phone password) installed something questionable. He added that he had also adjusted or replaced one or two other components, but that he had not charged for them.

When I got the phone back, everything was fine, but an hour later, when I unlocked it, it was reset, no apps, photo, etc., and the keyboard went from English to English – and – something pictographic, maybe Chinese. I restarted the phone and it looks normal again. But the battery drains twice as fast as it normally does, which leads me to suspect that something is going on in the background.

Troubleshooting – Sony alpha a6000 camera error

Assuming this happens with a known good goal (or no goal):

The shutter is pretty much the only essential moving part of an a6000 – there is no mirror, no aperture actuator, no AF motor, no from IBIS (there is however a sensor cleaning mechanism with an ultrasonic actuator). He would be a likely candidate.

The Sony FAQ indicates that this message indicates either a shutter, lens or IBIS problem. A6000 does not have IBIS. A lens problem can easily be isolated by not fixing a lens.

Other things that could have suffered damage and indirectly cause such a malfunction:

  • A switch or dial could have bumped to make contact in a pattern that is impossible when it is intact

  • External contacts could have bent and short-circuited (hot shoe, card outlet or lens mount)

  • Part of the metal case could have been bent enough to short-circuit something

  • A flexible cable was pulled out of its socket

  • Some heavy electronic components (for example, an inductor or an electrolytic capacitor) were sheared or broken on a PCB (unlikely that an a6000 package would survive this type of impact intact).

Unable to focus Nikon 500mm F / 5 lens with adapter on Sony A7Riii

I have a vintage Nikon Nikkor 500mm F / 5 Reflex lens around 1970 which will not focus endlessly with one of the Nik-NEX adapters that I need to connect this lens to my Sony A7RIII. The lens works great on a Nikon 7000 camera. The obvious problem I see is that the adapter is just a little bit too long. I am an amateur astronomer and my main use at the moment is astrophotography and my stars are not perfectly focused with the Sony adapter and camera. Any suggestion?

Moving from Canon to Sony

I have been on Canon equipment for over 5 years and I mainly photograph with 5DIII, I have a wide range of Canon lenses.

Thinking about switching to a mirrorless camera and I've read a lot about Sony and used Canon lenses with adapter on Sony.

I think many of them have gone through this process and would love to hear their experiences … is it worth spending $$$ to get new Sony equipment or stick with Canon equipment and upgrade new canon versions.

Do you use a Sony E mount lens on a Nikon camera?

It would only work at all with a manually controllable E-mount lens (IIRC none of Sony's own lenses) to be used as macro only lens. You would literally have to push the one inch lens deep into the mirror of a Nikon DSLR to be able to focus it endlessly.

If you don't want to sell the lens … get a simple E-mount body (some APS-Cs aren't expensive second-hand, say NEX-6) and use it. BTW, adapting Nikon lenses as manual focus lenses to E-mount cameras is almost trivial unless they are AF-P.
