@Tommi K1: Who wrote about RAID here ??

@cosmicnode : Yes I know ...

CF, XQD and Sony stick (what??) are dead.
SD and CF Express A (maybe) and B will remain. (Type C is not for photo cameras)

Yes the world is full of "amateur astrophotographers" using such UWA lenses. (BTW this is not astrophotography in the traditional sense of the word.)

These night landscapes are a current hype,...

I cannot understand all these (IB)IS crying.
Most DSLRs did not have IBIS and IS lenses for shorter focal lengthes were rare at least until a few years ago. How did we manage to make sharp photos a...

Most important: In case you have used the same e-mail / password combination at any other site, you must change your password at any of these sites asap.

.... and memory cards cannot prevent errors in camera / reader / pc.

In case of real card errors such a software is useless anyway.

You get/got free software with every Sandisk or Lexar card.
What is so special about this recovery software to pay 50 $/year ?

And what's so bad about XT-3 image quality?
Nobody will use a cam like this GFX for low light or high speed photography.

@MikeRan
Regarding size, lenses for the same reach will be much smaller and lighter than FF. But generally I also doubt that M43 makes much sense for real sports photography.

You can hardly compare the SRP of a new lens with a special offer of an older lense. Sigma lenses always get much cheaper after some time.

Tiny web images is proof of concept only.
Show me 24 MP images at 100% resolution. ;-)

Ilker:
Why do you think a lens has to be cheap just because it is APS-C ?
The size of a telephoto lens is pretty independent of the sensor size for a given focal length and aperture.

You just seem...

I also wondered about the focal lenght. (35-40-50)

But the 40mm was first designed as a Cine lense. And as the design already existed they offered DSRL versions, too.

I fully understand your wish for a slow but optically superb zoom. (Though I don't bother about shift.)
But actually I think only few people will buy it. It won't be cheap and who will pay (just...

"but does its size, weight, and cost, justify buying it? "

This is a question everyone can only answer for his own.

sportyaccordy:
How about you ignore discussions about lenses you neither need nor want?

Completely with Aleks7: Very annoying !! :-(

15 minutes video instead of 5 minutes reading
And I can easily read English but have great difficulties to understand spoken English. So please think...

dave8: That's irrelevant.

Some customers and agencies look at the images at 100% and they must be sharp then, otherwise they won't sell. Might be stupid, but it is reality for pros.

Yes of course, I am not silly....
But it is an important reason to use lenses with wide aperture.
