A wren briefly pauses on a cedar tree branch before delivering lunch to its nest of chicks.

Nebraska Governor Ricketts' Covid Emergency Declaration was issued the afternoon of March 13th. This image was captured that morning. Not the sharpest...too much haze/humidity.

A favorable review of the GR III was recently posted at KEH. The loss of the flash was the main criticism. I'm not a GR shooter myself, but know there are many fans/users here. Review: Ricoh GR III, A Luxury Compact Fixed-Lens Camera - Spotlight

My father's watch, beaten and scarred. It serves as a metaphor of him...beaten and scarred through decades of labor as a farmer and mechanic, finally retiring at age 70 and passing over at age 86. He was a good man and great example, scars and all.

I really like IR remotes, but sometimes sunshine does cause a problem (at least with the K-5 I had at the time this picture was taken). The secret to a good marriage is to always make your spouse look good...I really accomplished that outcome with this shot ;-) .

Corona virus prevention on cameras and lenses

Warning - Using alcohol on the camera body is ill advised according to Pentax. From page 128 of my K-1 operating manual, "Do not clean the camera with organic solvents such as thinner, alcohol, and benzine."

This makes sense because solvents can attack/degrade certain types of rubber, potentially risking damage to the excellent weather proofing seals in Pentax cameras.

A better idea, but one requiring much more patience, would be to put your camera or lens in sunlight for a number of days (rotating it to expose all surfaces for extended periods), allowing natural UV radiation do it's magic as a natural disinfectant.

I would recommend the good old brick wall test to see if the lens has decentering issues. I suspect that it does. My copy is very sharp and has very little in the way of CA.

Shutter shock with small primes

I used to shoot in Av mode nearly all the time. After noticing softness due to shutter shock using my FA 28-105, I've adopted shooting in TAv, typically keeping shutter set to 1/320 or faster. Huge improvement! If ISO starts to creep up beyond my preference, I either adjust EV increasingly negative, or switch mode to M and underexpose by a stop or two (or more) taking advantage of the sensor's wide dynamic range at lower ISOs. Then pull up in post with very good sharp results.
My two cents...
Daryl

Perhaps you have a dirty autofocus sensor. Probably a long shot but perhaps worth giving that area of the camera's internals some blasts of air. Here's a link showing where the sensor can be found, as well as how phase detection AF works. How Phase Detection Autofocus Works
Good luck!

Thanks Allen.
Omaha and Council Bluff's have fared pretty well because of the upgraded levee systems following the flood of 2011. Unfortunately, many other communities in Nebraska are under water. Pretty sad.

Just curious...I see you live in Topeka, but have family in Omaha. Is this the Henry Doorly Zoo rainforest your're talking about? If so, I would just plan on going into it first with the camera and lenses pre-warmed. The reainforest is near the zoo entrance, so I don't see much of a problem getting in there before your gear cool down. If you're here in the summer, I'd suggest you spend some time outdoors to let the gear warm up before going in.
My second two cents...
Daryl (in Omaha)

As others have said, camera and lenses need to be above dew point temperature (all surfaces, inside and out) of the environment you're entering to avoid condensation. How you warm your gear can vary depending on the resources you have available. If you're driving to the venue, maybe have your car heater blow on your gear while traveling.

I was at a groundbreaking ceremony for a new water treatment plant to get marketing related photos of the event. I got down low to achieve a unique perspective and eliminate distracting background elements from being in the photo. I was ready... everything planned out. Just as the dignitaries were gathering dirt on their shovels, this stray dog walked in front of me and looked back as if asking, "did you get the shot?". The client loved the photo, so much so that he put it on a plaque commemorating the event.

I agree that from 18 up it is usable. I lived with it that way for awhile, then bought a 15-30. Since then, I've hardly used the 12-24, though it might make sense if one wanted to pack light.
