Posted By: rjbrett, 03-08-2018, 02:27 AM

Welcome to Picture of the Week (POTW) for the period 1 to 14 March 2018. Iím pleased to be hosting this wonderful and diverse thread once again, and all are invited to contribute.

POTW is a great spot to show off six or fewer shots you take or are editing within the thread's date range. In other words, you can post your shots from this week AND last week.

To post your great photos, just hit reply and attach away

feel free to start immediately, if not sooner

Please:

ē consider including in your post any special circumstances or tips on technique or equipment which might be interesting to others.

ē identify your camera and lens if that information is easily available to you.

And please invite other Pentaxians to join us.

Some rules:
1) No theme, just post your favorite pix
2) Six or fewer images per person per thread to prevent thread bloat
3) Any Pentax, Ricoh or Samsung camera, film or digital

The current host will invite a new host via Private Message (PM), but if you are interested and willing to host POTW, please send me a PM, before I contact others.

My first two photos this week are of the large mirror windows at the Logan Shire Council here in the southern part of Brisbane. These were taken with the Cosina 20mm f3.5 on my K5, and were difficult to process until I realised that the reflections are polarised Ė hence the varying shades of blue in the skies. The well reflected gardens were what caught my eye.

Crotons grow well here, and this photo was taken using an Auto Takumar 55mm f1.8 at f8. I didnít think till after the fact that I could quite possible have found another aspect with more even lighting, but the colors still show well.

Weíve had 4 or 5 days of rain and showers on and off now, and a number of ladybeetles feasting on the grass heads on the lawn in between. I took some photos with the Vivitar AF 100mm f3.5 macro and a Kenko MC 3+ close up, and not happy with the detail I was getting went back inside, and, so I thought, changed it for a Kenko Pro1D AC 5+ close up. Later on when checking the lens I found I hadnít actually removed the 3+ filter, and had inadvertently stacked the 2. I have tried this with older close ups, and thought no, itís not worth the effort. This does seem to have worked, and Iím surprised I got this depth of field at this magnification (1.7 according to Cambridge online calculator).

That Miranda does look nice and sharp, and I like the colors. It’s reminding me of my Cosina 24mm, but the Cosina has more barrel distortion. I often choose the Cosina for that very distortion as much as the field of view, and have only just learnt how to correct it in processing. Have you corrected these?

Interesting looking fungi by the way!
I'm only just getting used to using it - I've been spoiled by AF and zoom - not really noticed any distortion but the Raw files do need the colours boosting a little but it does seem a good lens/

Thought I would post one more. Still on the K-3ii but with the D FA 50 f/2.8 macro and the AF160FC ring flash. Taken at f/32 for 1/180 sec, ISO 100 on my son's bike.

Shots from camping trip at Bisti Badlands in New Mexico. Near Chaco Canyon, it has some beautiful formations and colors. All shots except sunrise were taken on K-1 with either 14mm 2.8 Rokinon or 35mm 2.4 DA plastic fantastic on full frame. The cold woke me up to a beautiful sunset, could barely grab my K-50 with the 18-55mm kit WR lens and snap it.
