> from the economic point of view. Is it expected to make more money from FF 135mm prime than eg. fast standard apsc zoom Sony's emphasis on full-frame certainly seems to be paying off. Other ...

This is not credible information, but there's nothing "wrong direction" about adding more cameras. If you want to design a cell phone camera to actually gather more light, adding more cameras is...

That sounds great. The 85 f/1.8 is such an "easy choice" because it would be the one that is easy to carry, and gives the full "mirrorless experience" in terms of fitting so well with your camera ...

If you're open-minded about focal length, the 28mm f/2 is another small, light, portable lens, that happens to be a stop brighter than the 35mm you were looking at, as well as easier on the ...

Maybe you don't want recommendations for cheaper stuff, if you're set on GM and Zeiss all the way, but I do think some less-expensive options are worth considering: The Sigma Art series offers some ...

I got a Sony 28mm f/2 with my a7r iii -- great lens: small, light, reasonably bright, surprisingly reasonable price. That was when the a7r iii first came out, and more recently I upgraded to the ...

None of your answers really apply to me. I own both, but use the Tamron more often, and unless I specifically know that someone will value the extra reach of the Sony more than the f/2.8, ...

It doesn't sound like that's working for you. I always have Face AF on. AF Area can be wide (or not, if I was using another mode for focus on non-human subjects) but the important thing is that you ...

I just got the Sigma 135mm f/1.8 art and posted some sample shots from it yesterday on the Lenses forum: https://www.dpreview.com/forums/post/61968870 If you are are shooting people or other moving ...

I just started using the Sigma 135mm f/1.8. For portraits, it's terrific, especially for close-ups. (If you wanted to see the full upper-body, or shoot two or more people together, you'd need to ...

The Tamron 28-75 is great. Of course I still change lenses -- if you left the 28-75 f/2.8 on all the time, you'd turn your a7x camera into basically just a bridge camera without a lot of telephoto ...

Obviously, it's a great upgrade. I posted test shots in another thread. https://www.dpreview.com/forums/post/61863754  The new 24mm GM is a little bigger and heavier and a lot more expensive, but ...

Update: I just noticed that Lightroom says "Built-in Lens Profile applied" for shots taken with this lens. When I posted my test shots I said I processed them in Lightroom without any lens ...

Just walked around and took some shots with Sony a7r iii, converted to jpeg in Lightroom without any lens correction. f/1.4 : f/16: f/1.4: f/1.4: f/4: f/8:

I just got the shipment notice from B&H. I will soon have a 24mm f/1.4. In time for Halloween!

You said another one of your dream lenses was the 85 f/1.8 - I own that as well as the 24-105 f/4, and while they are entirely different lenses, I use the 85 f/1.8 more often. It's a favorite lens ...

The "equivalent" f-stop is only useful if you are trying to match the DOF of a full-frame camera. It's not even really useful in terms of exposure. If you shoot at 100 ISO, 1/100 shutter speed, f/4 ...

If you know you can afford the 24mm, and will appreciate what it gives you in aperture, bokeh, and wider coverage, and don't mind that it's a little bigger and heavier, and don't mind waiting a ...

That's what I did! The 28mm f/2 is an easy choice as a lens: affordable, light, portable, and bright enough for even extreme low-light situations when combined with a camera with good high-ISO ...

Yes. I have the same combo. Of course a longer zoom lens would have advantages for capturing your dog in different positions, or any sports/action photography, but the 85 f1.8 has good AF and ...
