i got a 50mm 1.7 lens for my pentax k-x and when i mount it on it goes to AV mode and it wont take pictures?? can you help me? im new at the pentax k-x...


I found myself in same situation as you when I bought my first manual lens coincidentally it was also a 50mm 1.7. To make a manual lens work, Turn on your K-x and press the menu button go the tab marked C in the C tab you’ll nptice numbers 1-4 go to #4 under 4 youll see the number 22  press ok on 22 and and change the setting from 1 to 2 this will allow you to use the manual lens. Now try hooking up your lens and taking a few shots. If you’re a beginner I suggest finding lenses with an A setting aka automatic apeture. If you don’t know about catch in focus yet lemme know! hope this helps if this doesnt work I’ll be glad to help again

I love black and white photos. They look elegant, aged, artistic and down right cool. The K-x has a black and white feature built into it that’s rather useful. I kicked it on today and viola I was taking my first ever black and white photographs! If you’re unsure how to pull this magic trick off here’s some instruction.

  1. Turn on your mighty K-x
  2. Select one of the following settings on the dial “P, Sv, Tv, Av, M
  3. Click the INFO button
  4. The menu will pop up and on the top left is Custom Image Bright click OK on it
  5. Another menu will pop up, touch the ISO button which is also the right button pad until the BW is highlighted
  6. Click OK and you’re ready to shoot in Black and White mode


Saw this scouring the intrawebs for lil tips n tricks.

Here are a couple of thinks you can do with your K-x that may not be immediately obvious:

1. Custom setting 20.: power lamp. (off) kills the blue power light from illuminating

2. Pressing INFO button twice kills the LCD, but it comes back each time you turn the camera back on UNLESS you go to Camera settings page 4: Memory page 2, and enable the checkbox next to Shooting Info Display. Now it will stay off if it was off when the camera was last turned off. Pressing the INFO button will bring it up if you need it.

3. Pressing OK button during normal shooting brings up the Select AF point screen.

4. If you only use LIVEVIEW for macro work, Camera settings page 3 liveview. enable show grid and change the focus mode to contrast detect, so the mirror doesn’t flip each time you half press the shutter. Contast detect is (very) slow, but accurate.

Using Manual Focus Lenses On The Pentax K-x

When I bought my K-x one of the things I was really excited about was getting to know and use the huge assortment of classic lenses Pentax has to offer. My 1st manual lens was a Ricoh Rikennon 50mm 1:1.7 (pin removed) I bought it off craigslist from a guy who was coincidentally a Pentax Forum member. After the purchase I figured I’d get things started and take a few test shots. I twisted on the lil’ 50, powered on my K-x and brought it to focus, pressed the trigger and nothing happened. I scratched my head a took a couple more duds… I was getting pissed at this point, cursing the camera, how could this new thing not work? If you found yourself doing the same I got you covered. I researched and found the answer, got it working in no time and took just a couple seconds. Here’s what you do,

Go into your camera’s menu go to the custom area and go to page 4 #22 Using Aperture Ring and switch it from 1 to 2 and you’re ready to start firing away.

PentaxK-x Firmware v1.02 Update

The K-x has had a couple firmware updates to allow better battery reading as well as adding support for 32gb and 64gb SD cards. I’ve updated to latest firmware and so far so good. Battery meter seems to be more accurate and I have yet to test a 32/64gb card on my K-x and don’t plan on it till the retail price is hovering just over $20. Below is a list of the updates and a link to download.

Changes to V1.02
  • Compatible with SDXC memory card.
Changes to V1.01
  • Added three kinds of particular effect shooting function (Pre-set 1,2 and 3) on [Cross Processing].
  • Added assignment of Cross Processing function to the green button.
  • Improved accuracy of Battery Level Indicator under specific conditions and improved stability for general performance.
