Family 4th of July celebration

Sadly the tree and wires were in the way. Part of the fun is dealing with challenges.

Really nice ones, John.

I'm envious -- never had success here with fireworks and 30-second exposures. The big shows have so many explosions so quickly that the longest I can keep the shutter open is 2-3 seconds. Anything longer and I end up with blown out highlights, no matter how small the aperture is.

Never had the K-5 (have K-30 and for me the biggest improvement is the extra focus points).

Worth noting these have all received my normal Lightroom noise reduction and sharpening. But I apply the same method to all sensitivities, just the amounts change.

Thank you bats, that was my first attempt. I'm pleased with them given the obstacles.

Thanks for the reply. I don't own this lens but I must say it produces one of the sharpest lines of fringing I have ever seen. I guess that's why I couldn't figure out what it was, it looked like purple fringing but then again not.

Thanks again
Greetings

Can anybody show how the files look at ISO1600 with no noise reduction under a 100% crop? Please?

I am about to get one.

There are heaps of reviews that provide what you are looking for. It's a bit pointless though because it doesn't reflect real world examples because everyone, with all cameras cleans up their images prior to presenting the finished product.

I'll do one up soon if nobody else beats me.

It all depends on the illumination and the scene.
ISO 1600, f8 and 1600/sec in the middle of a bright sunny day shooting a bright subject will look different [better, cleaner] compared to ISO 1600 at f1.4 and 1/30 sec in the middle of the night in a dark room shooting a dark subject.

The Imaging Resource comparator has ISO examples with default settings and standardised studio lighting for the camera. Their review of the camera also has a variety of test images shot with various levels of illumination [see bottom of page], down to 1/16 foot-candle light level, shot using various ISO's, and with NR turned on/off.

I would take a look at this thread: https://www.pentaxforums.com/forums/172-pentax-k-3/248079-k3-vs-k5-high-iso-noise.html. There are different samples at high iso in that thread, some are better than others.

Image looks fine to me?

Brisbane & Southbank by dcBear78, on Flickr

If I'd wanted a close up picture of a man with some bottles behind him I would've walked 30 steps closer. Comparing 100% crops with no post production done is pointless and completely irrelevant to the real world. On my 27" monitor at 1080p this 1600px wide image is bigger than A4 and looks to me, perfectly fine (although not the greatest picture in the world).

Went to Louisville Zoo the other day. Using the DA *200.
