How is your 16-50 autofocus accuracy in S-AF?

I often have trouble autofocusing my 16-50 towards the short end. It'll often front focus 1-2 meter. I've learnt to anticipate it and work around it by doing the zoom-in-focus-zoom-out-again thing.

I've also experienced the phenomenon described by the OP, with all focus points. I attribute that to an old worn SDM drive.

Favourite Exposure Mode

That's depending on the chosen program line. Program line is the trade off between shutter, aperture and iso and it's only applicable in P and green auto. You can choose the program line in P mode in the menus and you let the camera pick the program line based on focal length and focus distance when in green auto.

I know the "Normal" program line best. It has an inflection point where the light level corresponds to wide open aperture, lowest auto-ISO and 1/Fl shutter speed. In stronger light, it speeds the shutter and closes the aperture evenly. In lower light, it raises the ISO until it reaches max auto-ISO. As the light wanes even more, it starts to slow the shutter.
On the K-3 there's an additional inflection point for lenses f/2.0 and faster. The K-5 didn't have that.

Program line properties are hard to descrive in words as well as in pictures. If you're genuinely interested, I suggest you experiment yourself. Put the camera in P mode, pick the Normal program line and point it at different light levels to study what it does. I assure you it's completely deterministic and it's possible to understand it well enough to use it to your advantage when appropriate.

Regards,
-Anders.

If I'm at a place where the light is even and constant and I need to take many shots, I'm usually in M. Then I don't have to ride the EC for every shot. That could be on overcast days outside, or indoors in sports arenas.

If I move between alternating light situations, only taking a few shots every place, I'm usually in an automatic exposure mode. That would be Av if the scene is stationary or Tv if it's dominated by motion. If there's lots of light it's usually P.

Try in manual mode with iso 100, f/16 and 1/4000 and see where that takes you. If that still blows out the sun you'll need a ND filter.

It could also be red channel overexposure. That makes red and orange sunsets turn yellow.
Check your RGB historgram to confirm.

TR POWER PACK 3 FOR AF-540FGZ - DIY or alternate

If you want an external battery back for the faster cycle time, it'll have to be a high voltage power supply, not a 4xAA 6 volt DIY solder and gaffa tape job that connects to the battery compartment contacts.

I also recommend the JJC power pack, from personal experience.

Who gets in-camera JPEGs they like, even if they PP RAW files at other times?

There are lots of cases such as this one where the light and conditions are very static. There's time to set up the JPEG contrast, saturation etc. to give a great result for that shooting session. The key is to adjust JPEG settings to match the location, light and subject matter.

--Anders.

Yes, it's called shadow and highlight correction, not protection. You might need to set your ISO to something other than 100 to have access to highlight correction "on".

About the contrast highlight and shadow adjustment sliders, here's a rerun posting from me about those:

Yes, high contrast scenes are where RAW starts to make a lot of sense.
But the JPEG engine offers some tools too.
You should always expose for the highlights of course.
  1. You can enable highlight protection for that extra stop of highlight headroom.

  2. You can use shadow protection on mid or max to lift the shadows.

  3. You can use the high/low key slider to lift the midtones.

  4. You can use the contrast slider to lower contrast - that also helps to manage the scene DR.


In total, all those tricks can lift the shadows around 2.5 stops in camera.
To make it work in camera you need the time to eyeball the scene contrast. And you need
practice with the JPEG engine to set it up before the exposure.

Another life saver is the "save as raw" feature. That thing makes me dare to shoot a lot more
stuff as JPEG than I'd otherwise do.

Yet another life saver is the ability to redevelop the most recent shot again and again
with different JPEG settings, including shadow protection and white balance.

Here's an old JPEG example of mine, where I spot metered to put the clouds at +2, used contrast at 0,
highlight protection on and shadow protection on max with the monochrome image style.



Regards,
--Anders.

You can also bring up the shadows in camera JPEGS with the shadow protection feature.

But in your case (get it right now or wait till next year?) I'd at least shoot RAW+JPEG for insurance.

Love your work, BTW.

Sports. It works for sports.




I've never really understood this "which focal length for what subject"? discussion. Either the focal length follows from the distance and the desired framing, or it follows from the kind pf perspective you desire. I've also shot sports with an UWA and it's completely different but sports nonetheless. Like this:

What settings on K3 for flash in daylight?
Posted By asp1880
Replies: 9
Views: 1,914
I'd gladly go with P mode and P-TTL for daytime outdoors fill flash work. And I'd also go with auto ISO but that's just me.
If it's sunny, aim for backlit shots with -1/3 or -2/3 exposure compensation. That will reduce both the ambient and the flash exposure.
Also consider using a 1/4 CTO gel on the flash to give people a nice tan.
If it's overcast, set -1 to -2 flash exposure compensation for just that slight touch of fill flash to brighten up the faces. Don't gel the flash.


On ND filters versus HSS, they rob you about equally of flash range. The only way to gain flash range shooting into the sun is with
faster sync speeds. Or more flash power of course.

--Anders.

What custom image is set on your k-5? Bright? Natural, vibrant, reversal film? And what hue and saturation settings?
Try natural with hue+1 or muted with saturation +3.
