Wow, I feel like I won the lottery.
Sorry to hear about your mix up too.
I hope that you all get your correct lens soon.
And I'll be seeing your pictures in the TS lens club!

I picked one up at $558 and it just came.
Guess the fixed something because I got the correct lens.
Hope your exchanges go well.

Been watching for a price drop on the 28-105 for over a year now with no success. Even though we pay sales tax it's the best price I've seen in a long time. Thanks for the tip!

Thanks for the post.
I've been eying the 12mm and just put Laowa on my watch list today.
Used the savings to pick up the NiSi filter holder for it.

With B&H, if there is an issue with the lens then they issue a return and you don't pay for shipping.
Adorama makes you pay shipping for a defective lens?
I had an order with them but I was notified that it was out of stock. If it costs $35 every time to return a defective lens then I will try it from B&H instead.

I have my K3-II set to use the AF button on the back.
I press and release it quickly about a dozen times - never waiting for it to actually try to focus.
Between 1-2 dozen presses it "wakes" up and works.
I have to do this every time I use the lens (used rarely and sits on the shelf a lot).

So, how do ~you~ protect your D-LI90's ?

A little piece of gaffers tape over the end on mine.
This is also how they want them protected when flying.

>>I've switched to using the Kingston MLWG2

Alas, after my trip to Iceland and trying to transfer 32GB of data through the Kingston I cannot recommend it.
Data transfer speed really bogged down on that many files and that much data. It was going to take hours to back up 1 card.
My previous tests with smaller amounts of data led me to believe that it would work for more files but it doesn't.
I've moved on to a small Dell laptop (14z I7) with Win10 on a SSD and a USB3 port that performs admirably.

I spent 9 days in Iceland and used the MindShift backpack to carry all my gear.
No problems carrying it on the plane.
I took out the waist belt and put it under the seat in front of me so I could take it out during the flight to take pictures.
I was able to fit in the: K3ii with 16-85, 1.4x converter,DA 55-300, DA 12-24, DFA 100mm macro, 15mm and a Samyang 8mm. Tight squeeze but it works with APS-C!
I stacked 6 lenses together with a OP/Tech double lens mount cap to save space.

I was just there for 9 days in late April.
Planned for rain and wind and got a sun tan instead!
We used this map for planning the trip: Map of Iceland for photographers, hikers and tourists
I used the MindShift backpack to carry all my gear: MindShift Gear rotation180° Professional Backpack Deluxe 210
I highly recommend this to hold your gear.
I was able to fit in the waist belt: K3ii with 16-85, 1.4x converter, DA 55-300, DA 12-24, DFA 100mm macro, 15mm and a Samyang 8mm. Tight squeze but it works with APS-C!
I stacked 6 lenses together with a double lens mount cap to save space: OP/TECH USA Double Lens Mount Cap for Pentax Lenses 1101251 B&H
Also brought a tripod, Nikon SB-30 and monocular.
And bring a hat that ties under your chin!
The K-3ii has GPS built in so bring an O-GPS1 if you bring your K-3.
Lens usage: 16-85 was lens used most often followed by the 55-300 (sometimes with the 1.4). Used the 8mm once and the 12-24 a few times. Never used the 15 or the 100.
I decided that if I needed a wider angle I would just use the 16-85 and take several pictures to stitch later.
Now when I travel I only bring my 16-85, 55-300, 1.4x. flash and filters.
Here's a few days worth of images - haven't processed them all yet: Iceland 2016
Have a great trip and watch out for sheep! :)

You would need to look up your portable drive specs, but let's assume it uses 500mA to run. With a full charge the Kingston is rated at 4640mAh. Your hard drive would run roughly for 9 hours before you would need to charge the Kingston. They can support larger drives but it would likely require a powered USB hub.
Copying to multiple devices is my theft/destruction protection. With multiple memory cards kept in the camera bag and each SSD containing all the backed up pictures in other carry on gear carried by myself and my spouse, I believe I am covered for most normal theft/disaster scenarios.

I used to bring a laptop along to back up all my images.
I rotated cards and would not use it again unless I ran out of memory cards.
Problem is the laptop was large, heavy, and a single point of failure.

I've switched to using the Kingston MLWG2 (http://www.amazon.com/Kingston-Companion-Storage-Charger-MLWG2/dp/B00KU2E9IW).

At the end of a shoot I place the SD in the Kingston and hook a 256GB external SSD to the USB slot.
I use the Kingston app (IOS and Android) to transfer files from the memory card to the SSD.
I put in another SSD and repeat the process.
I now have my original images on the SD card and backed up to two Solid State Disks.
The memory card gets rotated out and will only be used again if I run out of memory cards; but my data is backed up on 2 separate disks kept in 2 different locations.
I use SSD instead of spinning platters because fewer moving parts means less chance of disk damage.

The MLWG2 also acts as a battery charger and wireless device.

With the Kingston app or ES File Explorer I play movies off of a SD card or disk for up to 4 people, or I can review my images.

Look into a Bowens Illumitran slide copier.
I picked one up and am finding it much easier to use and does as good as a job as my dedicated slide scanner.
I'ts also easy to vary the light in case you want to make the image brighter or darker.

On person reported here: https://www.pentaxforums.com/forums/58-troubleshooting-beginner-help/306389-pixel-shift.html that by using DCRAWPS they pulled out 4 images but it was unknown if they were all the same or different.

You can use DCRAWPS to color the "movement area" with purple so it can be fixed: https://www.pentaxforums.com/forums/172-pentax-k-3/296497-implementing-automa...hot-dcraw.html

A little more reading about it here gives some insight into the command-line switches: https://www.pentaxforums.com/forums/172-pentax-k-3/304968-pixel-shift-may-actually-winner-5.html

I think a viable workflow would be to take a RAW+JPEG. Clean up the raw file using PDCU as noted here: Pentax K-3 II Review - Processing Pixel Shifted RAWs | PentaxForums.com Reviews

Then layer it with either the jpeg or an image pulled out from DCRAWPS and brush out the bad parts and flatten your image.

Note that there may be issues with shooting DNG or PEF as noted here: Some results from the K-3 II: Pentax SLR Talk Forum: Digital Photography Review

I'll have some time this weekend to test it if nobody reports back their try by then.

Software to remove raster from a scanned image?
Posted By c57d

I am scanning old photos and just went through the same process.
The best/easiest method I found is to use ImageJ: Download
Here's and example of what it does using an older plugin for Photoshop: RetouchPRO Tutorials
And a YouTube video:














You Tube



But using ImageJ is easier than a Photoshop plugin.
Assuming windows here, but they have downloads for other operating systems too.
Download and unzip the file.
Open up the ImageJ.exe
Click on File, Open and open your monochrome or color image.
Click on Process, FFT, FFT.
Click on the Paintbrush Tool.
Doubleclick on Paintbrush Tool to set circle size. Change color to black.
Put a black circle over every star except for the central one as noted in the previously mentioned videos/tutorials.
You can also hold down ctrl-shift and move mouse left or right to increase/decrease circle size.
When your black circles are done, click on Process, FFT, Inverse FFT

I've started to make really big circles and blacken the quadrants; and I don't see a difference between that and making a small circle on each spike. It's faster too.
If you see a spike on the main horizontal or vertical spike you can blot that one out too, but never do the central spike!

Browse the web for more info on ImageJ. Looks like an amazing program.

Happy photon hunting!

K-3 II and Sigma 18-35
Posted By c57d
Replies: 8
Views: 1,434
My Sigma 18-35 always needed to be focused with live view (CDAF) on my K-3 at all focal lengths at f1.8.
I performed the same test on my K-3 II and now CDAF and PDAF focus properly.
I tested this under incandescent and natural lighting; at close and far distances and different subjects.
The lens had never been adjusted with the Sigma dock.
Can anyone else confirm that their K-3 II focuses better with the Sigma lens than their K-3 did?
Not sure if there was a change in the K-3 II that "fixed" the focus problem that the K-3 had with this lens.
Or maybe I just got lucky and all the planets aligned so that I don't need to use live view anymore!

K-3 Power-on issue

My power-on issue has also been resolved with this new update but a new problem cropped up.
When I take a picture with the on-board flash up it will continue to take flash pictures without my pressing the button.
I powered off, removed the grip and tried it again with the same results.
I ended up doing a reset and now it works as expected.
I can't explain why the reset fixed it but I'm glad it's acting "normal" now.
Also, my 18-135 would hunt for focus on 2 different K-5 cameras and a K-5iis but it works fine on the K-3. Weird.
