Partial Workaround for Body Aperture Block Problem with Lens Aperture Ring

First, you need to enable this in the Custom Function:

 

Second, you need to set the aperture ring of your K-mount lens out of the A position, provided that your lens has it:



Now, your semi-dead Pentax camera will work in the Av and M modes with correct exposure, as long as a non-A aperture position is selected. The credit of this clever method belongs to Mr M R Padmaraju of the DPR Pentax forum, the thread of his original post can be found here.

PC Remote Control Software for Pentax DSLRs (via Wi-Fi)

Despite that the software was designed for the K-s2, a Pentax user reported that it worked for his K-1. So, it you try other Pentax models, please report your finding here! :-)

Image Sync Version 1.1.2 is Up

It seems that Ricoh is reading my Blog, now there is a new version of the Image Sync, which can be updated at the Google Play, for Android only. The official website has not yet been updated, though. (Edit: The official website has just been updated and it indicates that the update is only available for Android only.)

Newly added feature on version 1.1.2
･Android 6.0.1 support
･Connection performance improved.

【Feature】
1.View and Copy Images
You can view images taken with your camera and copy them to your mobile device.
You can also upload them to SNS sites.

I will try and see if it improves.

Ricoh Image Sync Updated

Now it can save image under individual image view. But yet I still hope that it can save the downsized image from that preview, the resolution is simply enough for most mobile applications and sharing purpose.

645Z and K-s2 TIPA Awarded

http://www.tipa.com/english/XXV_tipa_awards_2015.html

Everyone got an award anyway. And, I just wonder why the K-s2 is an "advanced" DSLR whilst the D5500 is an "entry level". They are direct competitors in the same market segment and price tag range afterall!

Btw, here is an YouTube direct comparison review of the two, for those who are interested:

The IQ is not bad IMO. But wait, a K-s2? APS-C, not FF?? ;-D Do note the aperture values also.
