Cryptic SD cards definition explained at last by Explora.



If you ever wondered what all those SD card numbers and definitions mean than jump over at Explora (Click here). If you don’t have time to read the full article here is the shupershort explanation:

  1. Name: some card manufacturers identify their card by the targeted user; in this case, the Lexar Professional series is aimed at photographers and videographers.
  2. Read Speed: the speed at which data is read from the card.
  3. Type: as mentioned above, this will either be SD, SDHC or SDXC. Differences in capacity or speed are shown elsewhere on the card.
  4. Another speed rating, which can be calculated into MB/s with this formula: x rating/6.6666 = MB/s. 1000 ÷ 6.666 = 150 MB/s
  5. Class rating: this is the minimum sustained data writing speed, and class 10 is the highest right now, capable of 10 MB/s. The slowest rating is Class 2, which has sustained data writing speeds of 2 MB/s.
  6. UHS Rating: The UHS rating and the Class rating are closely intertwined. UHS rating of 1 means that the minimum sustained data writing speed is 10 MB/s, and UHS 3 is 30 MB/s. However, the UHS rating is more important for shooting 4K video, as the minimum data rate must be higher so frames are not dropped. For photographers, a UHS 1 and a Speed Class 10 is basically the same thing; however, the UHS cards are more effective in a device that supports UHS bus architecture, and not all devices do. So conceivably, you could have a Speed Class of 10 and a UHS 3 rating, but without a UHS device, it defaults to the speed class rating of 10.
  7. This number shows what UHS standard this card conforms to—I or II. There are four bus speeds for memory cards: Normal, High, UHS I (Ultra High Speed), and UHS II. This number shows what the bus architecture of the card is. These classifications were designed for theoretical jumps in speed, and added as the cards got bigger. There is no difference to the end user between a UHS I or UHS II card.

Panasonic GX8 now in Stock in USA.


The Panasonic GX8 is in Stock for the first itme in USA via BHphoto (Click here).

First and very detailed long GX8 owner review at Amazon Germany.

Dylan: Here are some vanilla jpeg shots from the new Lumix GX8 with no processing apart from whatever the camera itself does at low and high ISOs. Photo mode is “Standard” apart from the georama filter shot. The dynamic range looks pretty good and highlight fall of in-particular looks smooth.

Kowa Prominar 25mm f/1.8 MFT lens tested at Photozone.

Image courtesy: Photozone

Photozone posted their full Kowa Prominar 25mm f/1.8 MFT lens review:

The Kowa Prominar MFT 25mm f/1.8 faces a difficult task especially given its price tag of 800US$. The 25mm segment is covered by a variety of lenses which are either much faster, much cheaper or both. However, the Kowa lens has at least one advantage – optical performance. The image quality is decent at max. aperture but when stopping down it is about as good as it gets on the micro four thirds system.

The Kowa Micro Four Thirds lenses on eBay:
8,5mm f/2.8 in on eBay (Click here).
12mm f/1.8 in Black (Click here), Green (Click here) and Silver (Click here).
25mm f/1.8 in Black (Click here), Green (Click here) and Silver (Click here).
