What SD CARD should I buy?

If you want an SD Card for your camera - these are the ones I use and recommend. 

I'd strongly recommend not to buy any SD cards off ebay - I've heard about too many issues with counterfeit cards - often sold on by unwitting resellers. My inbox regularly gets messages from people who bought a £150 camera then cheaped out and bought a £3 memory card on ebay - Then when it doesn't worth they blame the camera! It doesn't make any sense. Good memory is cheaper than it's ever been - see the links above.

A lot of HD cameras will not work properly with cards larger than 32GB (cards over 32GB are usually SDXC rather than the SDHC standard used by 32GB cards. SDXC cards use the ex-FAT system rather than FAT32 - in short they are a different standard). - so don't just buy the biggest card you can afford - read the specs in the manual to see what it accepts.


RECOMMENDED CARDS (for action cams - see dashcams below)

CLASS 10 UHS-1 CARDS (For HD Cameras)


U3 CARD (For 4K cameras)




The SD card in a dashcam is re-written over, more frequently than in other types of cameras. Some manufacturers void their guarantee if an SD card was used in a dashcam. So, no surprise, there are special High Endurance SD cards made just for's some.


VERY IMPORTANT. These links take you to the product, however Amazon have three different ways of selling. There's Amazon Direct - This means that you are only dealing with Amazon themselves, then there's other sellers that use Amazon's facilities - these show as Fulfilled By Amazon and finally there's Market Place sellers that advertise on Amazon, but operate independently.  I strongly recommend that you only use the first...the Amazon Direct - Sold By Amazon option. Even if it appears that you are paying a couple of £/$ more it is more than likely you are comparing the price of a real item against the price of a fake.

To give you an idea of the extent of the fake goods problem. In a 2016 survey by Apple - 90% of the 'Apple' chargers sold through Amazon - using the other the two methods..which includes the "Fulfilled by Amazon" option -  were found to be counterfeit....90%!

Sony TG3 wide angle lens comparison


My Sony Wide Angle Lens - the VCL-HGE07TB - arrived this week and I spent my lunchtime today in Manchester trying it out.

I've put together a video comparing the normal camera lens against my original Magnetic wide angle lens solution and the official Sony one.


The Sony one is 0.7x and the Magnetic one is 0.45x (I think). After a few minutes of testing, the Sony solution was the obvious winner. It is definitely worth the extra cash despite the slight reduction in the width of the image compared to the magnetic lens.

The main difference is that with the Sony the whole image is useable without any vignetting in the corners. The vignetting on the Magnetic Lens is not visible on the camera's LCD when filming - it only shows up when the footage is transferred for editing (the camera films more than it shows on its screen). This means that clips taken through the magnetic lens  normally have to be reframed when editing (which takes extra time and effort)

The lens fits well (despite it being designed for the newer model) and stays firmly attached. The lens does seem to blur the footage slightly, so its probably best to only attach it when its really needed. It will be invaluable for indoor shots in confined spaces. On my next holiday I'll probably clip it on automatically whenever I enter a building I'll be filming in - like a museum or gallery.

In the video I label the footage as Normal, Magnetic Lens or Sony Lens - hopefully that's self explanatory. For earlier posts about the magnetic lens and the Sony TG camera click here.

Thank you so much. Your comparison on the lenses has been invaluable. I appreciate youtaking the time.

Thanks for the kind words- glad I could be of help.

You say the sony lens tends to ...."blur the footage slightly"
Do you mean blur as in out of focus, or just not as distinct? Is it that noticeable? Other than that comment i am sold on the idea of getting one.

It's just my perception that the footage seems a bit out of focus with the lens attached. I suggest you view the video (in HD) and see if you can spot it. I noticed it on the first clip especially - check out the number plates on the motorcycles starting at around 46 seconds in. The Sony lens does seem to make everything just a little bit softer.

Can you mount a filter (pola) to the front of the VCL-HGE07TB? And what is the approx. size of the front element?

many thanks, love your work.

August 3, 2009 | Unregistered CommenterJeffrey Hogan


Unfortunately there is no way to attach a filter to the lens.
The glass is 35mm across.

Many thanks for your comment.

Anyone found further low prices for the Sony wide angle lense above? (VCL-HGE07TB)

August 7, 2009 | Unregistered Commenterchas c

The footage is not so sharp with te wideangle because the TG 1/3 doesn,t have a option in the camera for wideangle like the TG7

August 26, 2009 | Unregistered Commenterhans

@ Techmoan, did you try manual focusing also ?

August 26, 2009 | Unregistered Commenterhans

No I must admit that I left it all in Auto. The slight softening of the image was only apparent when I put the footage on my laptop screen at home. Next time I'll try manual focus when I am filming distant scenery and wide vistas. It's only a minor problem - indoors I'd still choose to use the lens to gain the extra width over the slight reduction in sharpness.
