Yes

I have supplemented my Pentax K1 by a Sony A7RIII 3 years ago. I now essentially use the Sony except when weather resistance is necessary. I don't know about third party lenses, but I am extremely ...

You are not the only one.

I would worry more in the case of a mirrorless camera (I am very careful with my Sony A7R3). But the SLR has the mirror protecting the sensor all the time except when the exposure is made. I have ...

Regarding landscape photography, the a7R3 is excellent for reframing and cropping. I have been using it with the 24-105 f:4 which is sharp enough to enable cropping and replaces a longer focussing ...

I have been using a Sigma WR ceramic protector to very good effect with my 24-105. No visible reduction of sharpness.

Very nice ! I tried applying Topax Sharpen AI - motion blur to your image. Does look a bit sharper:

Does the Adobe DNG converter recognize the raw files ? I still use Photoshop CS6, but have to convert the A7R3 raw files to DNG because CS6 does not recognize them.

I agree with that. I turn my A7R3 off while hiking but remain on the lookout all the time.

Very good! "Dynamically constraining" effect.

In Turkey - where I was born and spent my childhood - "kara kurt" would mean "black worm". The word "kurt" is often also used to designate an insect - as also "böcek" (pronounced "bödjek"). ...

Looks like it is related to the Black Widow, or to the Cara de Gatto found in Chile which has about the same size and appearance and has a deadly bite.

Troll juice ? ;-)

Apple's strategy is based on programmed obsolescence. A well-known fact.

It depends onwhat you mean for "quality". Personally, I got the a7RIII when it became available, and also got the 24-105 G OSS. The optical quality of the lens combined with the high resolution of ...

"I don't need that - I'll stay with the existing gear !" :-D .....

Has the surface features of the full moon but with horizontal stripes. Must be a reflection - from sensor to lens and back ? Or somehow else ?

Beautiful pictures ! Must be in the surroundings of Guardia ? I spent some time in Zernez - but that was over 50 years ago.... You are lucky to live there ! Concerning the Russian scientists - I am ...

Yes,  Keep control.  Think of the Boeing 737 MAX....

I would not go for the Rii. Battery capacity is too low. For a small difference in price, the A7Riii is far superior. I have been using it with a 24-105 G OSS and hardly need to change lenses in ...
