Pentax K-1 compatibility with Metz Mecablitz 50 AF-1 digital

Category : Photography Oct 18th, 2016

Shocked me when Metz Mecablitz 50 AF-1 digital is not working well with Pentax K-1, although it is a third party lens, it should work well as it used to be on my old Pentax K-30. All images are over exposed on TTL (through the lens) mode, forced me to use manual mode to get acceptable result.

Try my luck on official site of Metz Mecablitz 50 AF-1 digital, then only realised there is an firmware update released on 27/07/2016.

Steps to update: (Windows 10)

Preparation before firmware update, download file below:

Firmware: MB 50 AF-1 digital Pentax V5.0 Win – (3.6 MB)
note that windows driver “Driverinstall.exe” and firmware update instruction title “Metz…Windows_2010.pdf” are available in extracted folder.

i) extract downloaded files
ii) execute “Driverinstall.exe”
iii) connect flash unit to PC through mini-USB cable (i used external HDD USB cable)
iv) run “FirmwareUpdateGB.exe” (red icon) under “Pentax MB58 MB50 MB48 MB44 D” file
v) follow its instruction and start firmware update, it takes around 1 minute to complete
vi) complete and test the flash unit


Fortunately, the flash working well with accurate exposure thanks to the firmware update.

Huawei and Honor: Screen Lock Shortcut / Icon / Button

Category : Tech Aug 29th, 2016

Both Huawei G8 and Honor 6 Plus got a new firmware update, which is EMUI 4.0 (Android 6.0.1). Took around 20 minutes for the installing / optimization progress, after reboot in home-screen, my partner pointed out missing of screen lock icon which we always use.

The screen lock icon / button act as an alternative way to turn off and lock your screen without pressing on physical power button of the phone. Another way is to lock screen is through “Floating dock” which you can activate at Setting -> Smart assistance -> turn “Floating dock” On, there will be a lock icon in it.

However, we still miss the Screen Lock Icon that comes with system app in EMUI 3.0. So, me done some search and found a solution, as below:

i) install ScreenLockEMUI.apk

My Pentax APSC Lens Line-up and Future

Category : Photography Aug 6th, 2016


Been into Pentax system for a long 4 years, collected numbers of lenses. Trying to putting off some crop sensor lenses and ready for Full frame lens. Here are the current line-up,

Body: Pentax K-30
Flash: Metz mecablitz 48 AF-1
Kit Lens: Pentax DA 18-55mm F3.5-5.6 AL
Ultra Wide Angle Zoom: Sigma 10-20mm F4-5.6 EX DC
Wide Angle Prime: SMC Pentax-M 28mm F2.8, Sigma 30mm F1.4 EX DC
Standard Zoom: Tamron SP AF 17-50mm F2.8 DI ii XR LD Aspherical (IF)
Standard Prime: Super-Takumar 50mm F1.4, SMC Pentax-FA 43mm F1.9 Limited
Short Tele Prime: HD Pentax DA 70mm F2.4 Limited (Silver), SMC Pentax-FA 77mm F1.8 Limited
Telephoto Zoom: Vivitar 70-210 Series 1 Macro (K Mount)


Planning to go full frame, still not sure whether to stay with Pentax or jump ship to other brand. For now, Pentax full frame lenses such as HD PENTAX-D FA 28-105mm F3.5-5.6ED DC WR , HD PENTAX-D FA 24-70mm F2.8ED SDM WR and HD PENTAX-D FA 15-30mm F2.8ED SDM WR prices are very high for me and no 2nd hand in market yet.

IMHO, there are some points that makes no sense, such as: “The lens is essentially a rebadged Tamron SP 24-70mm F2.8 Di VC USD lens from 2013 with the in-lens stabilization mechanism removed.“. Why not set a lower price since it is not a ★ lens, or else, just include stabilization mechanism. Since shake reduction on Pentax K-1 is electronic based which result jello effect while panning, on-lens stabilization mechanism in this case will definitely help a lot while recording videos. Moreover, we can always off it when sharpness needed for still image.

The kit lens, HD PENTAX-D FA 28-105mm F3.5-5.6ED DC WR that selling for RM 2,000 (only if bundle with Pentax K-1, RM 2,500 for lens only) where others long time offering wider zoom range with fixed aperture: 24-105mm F4 (Canon) and 24-120 F4 (Nikon).

Third party lens, Tamron releases some amazing prime lenses recently, and there seems no K-mount planned for near future. Also wondering will it be like the case of Tokina, where Pentax start rebadging Tokina lens, therefore, no Tokina branded K-mount lens after that. As for Sigma FF lenses, some have Pentax mount, some not, refer here: DG for Full Frame

Video, camera of year 2016, without 1080p 60fps (only 60 interlaced) and proper shake reduction, this is non-sense.

Future, will Pentax system worth to invest, such as, after bought the FA 31mm limited, they come out HD version of it not long after, as there are large aperture prime lens planned in road map.

Understand Pentax K-1 is still image concentrated camera, with its smaller body size compare to others, well performance of holy trinity (disregard slower focusing, color fringing and chromatic aberrations) on full frame and many legacy lenses available out there. It is okay if there is plenty of budgets, but for poor guy like me, it just seems very hard take take the step to enter Pentax Full frame system, at least for current timeline.

Relocate WordPress to New Domain

Category : Tech Aug 5th, 2016

Days ago, shifted WordPress to a new domain name / URL. Right after shifted to new domain name, it shows database error. Took me sometime to surf and google around to find out solutions. In my case, these two ways solved all the problem and the site is now up for good.

i) Went into cPpanel -> public root -> wp-config.php, and change old database name to new one, due to Exabytes technician changed the old name in server side. So, i have to manually change it in WordPress wp-config.php file.

Note: to check your new database name, check it at “MySQLDatabases” in cPanel, under Databases section. if you want to know password for database, you can refer to wp.config.php again, it was stated inside.

ii) took me sometimes to figure on this one, too much of similar articles but none really helps. My case: did all backups but forgot to replace new URL in WordPress -> Setting -> Permalinks. Luckily, found a simple way to do it, stated here: Relocate Method, as below:


1. Edit the wp-config.php file.

2. After the “define” statements (just before the comment line that says “That’s all, stop editing!”), insert a new line, and type: define(‘RELOCATE’,true);

3. Save your wp-config.php file.

4. Open a web browser and manually point it to wp-login.php on the new server. For example, if your new site is at, then type into your browser’s address bar.

5. Login as per normal.

6. Look in your web browser’s address bar to verify that you have, indeed, logged in to the correct server. If this is the case, then in the Admin back-end, navigate to Settings > General and verify that both the address settings are correct. Remember to Save Changes.

7. Once this has been fixed, edit wp-config.php and either completely remove the line that you added (delete the whole line), comment it out (with //) or change the true value to false if you think it’s likely you will be relocating again.

Note: When the RELOCATE flag is set to true, the Site URL will be automatically updated to whatever path you are using to access the login screen. This will get the admin section up and running on the new URL, but it will not correct any other part of the setup. Those you will still need to alter manually.
