This lens calculator has field of view and lots of other lens info, including width of view in feet or meters at a selected distance .

Good to hear both the lens and the FTZ were okay. I figure either a bobby pin: or one of these :-O

I like to use fast raw viewer to cull a photo session to a smaller set of images to load into the photo editor and decide which to edit. I have it set to use the Delete key to send the current ...

U1: hand off to anyone for group photos. ("AF-On only" is too hard to explain for a one-time user.) Mode dial=Auto, AF-C, Wide-area L auto focus, auto-ISO, auto white balance. Just point and shoot! ...

With my 70-300 on the FTZ, I can feel a little movement and hear clicking sounds as I turn the FTZ without using the release.  The pin fits into a small hole on the lens, so there's a slight ...

The other annoying distortion on wide angles is with people near the edges of the image. It's noticeable even at 24mm, but is extreme at this 14mm view. 14mm, jpg straight out of camera. The people ...

I use DxO editing software, with the Viewpoint add-on. This allows a lot of perspective corrections, very useful with wide angles. 14mm jpg straight out of camera. I wasn't using the camera level ...

I had the same reaction with the first tests of my 14-30. Yikes! But now it's an interesting challenge to either minimize the wide angle effect, or to use it to the max, depending on the image. A ...

I saw that darktable has a negative processing tool. (I haven't used it myself.) This video is a good intro to it. (The video shows darktable version 3.2. It's now on version 3.4, with an updated ...

It's interesting to experiment. Find a closer object with a somewhat farther background.  See how much of the object has to be within the box to make it focus on it.  It does seem to depend on the ...

Zoom in on a star or other point source of light. Use the "+" button. 1 press= 50%, 2 presses=100%, 3=200%. (I actually have the F2 button set to 100% zoom, very handy.) I've used the 100% zoom ...

I've seen some good polarized images at wide angles, but these had little to no sky.   For example, a forest and creek image, where the polarization worked great on the plants and water. Some tech ...

The 32GB XQD cards are less than 80 EUR or $100 US. That's what was bundled with my Z6, and its big enough for photos. At maybe 1GB per minute for video, it's small if you do lots of video.  Oh! ...

Z6 in dim light with F1.8 vs F4 My Z6 is fine for night shooting in the city. Streetlights are plenty of light for focusing. I do notice that my 50 F1.8 focuses faster in dim light than my F4 lens. ...

Copying speeds test I like the card reader instead of using the Z6 USB cable. I had done this before, on my old laptop. There, I found that the Sony USB card reader was 10 times faster than the ...

You can try using an air blaster bulb that's designed for dusting lenses.  But this almost never works for me.  The tiny dust particles are kind of stuck  on the sensor, from static type ...

Yes, that exe file. Windows Defender blocked it, saying it's from an "unknown publisher" (unlike the 3.2 download from the darktable.org site). I told it to Keep it. And had to click through a few ...

I added the 50 1.8, and had the 24-70 from the start. I use the 24-70 way more often, but the 50 is great fun. It's an interesting challenge to stick with one focal length. With the 24-70 F4, I get ...

I'm thinking about getting the 24-200 for a one-lens hiking setup. I want to avoid changing lenses out on the trail. With my 24-70, I often wish for reach beyond 70mm. I also like night shots in ...

I did a quick test of 14-bit NEF + jpg "Normal*" pairs on my 32 GB card. 90% full was 715 image pairs. or 70% full with no jpgs. See my previous comment in another thread. A 128GB card should hold ...
