SPP 6.0.4

The JPEG/TIFF saving issue with X3F files from Merrill cameras is still there on my machine (Windows 8.1) and despite the instructions.

As a side note, Sigma Photo Pro 6.1 − which is expected to support all X3F files regardless of the camera they are from − is set to be released in August. Meanwhile, we have to deal with what seems to be a beta version.

Here is the list of what the latest iteration is meant to correct.

For Windows

  • It has corrected the phenomenon that the software occasionally fails to open the X3F files taken by the SD1, SD1 Merrill and DP Merrill series.
  • It has corrected the phenomenon that it does not save the capture date information when the images are saved in JPEG and TIFF formats.

SPP 6.0.3

A new version of SPP has just been made available for download.

Does it finally fix the issue sometimes encountered on Windows 7 and 8, when saving to TIFF or JPEG an XF3 file taken with a Merrill camera? I promise the answer will be shorter: no.

It is not a compatibility issue. As per Sigma:

The latest version, SIGMA Photo Pro 6.0, is only compatible with the RAW data of the Quattro series, Merrill series and SIGMA SD1.

The following has been fixed:

For Windows

  • It has corrected the phenomenon that the software occasionally displays the message “File I/O error” at the time of startup, and becomes frozen.
  • It has corrected the bugs that display images in Display Quality Priority Mode improperly when they are recorded in 3:2 aspect ratio. Images that are recorded in an aspect ratio other than 3:2 were often saved in the wrong aspect ratio.

SPP 6.0.2

UPDATE: I successfully saved a few files but I am now having issues again, as are many other users. No more error code, but either an empty JPEG/TIFF file, or nothing.

Sigma Photo Pro 6.0.2 is available for download. This new release corrects few but important things:

For Windows

  • It has corrected the phenomenon that the software does not save images properly when SIGMA Photo Pro 6 is launched by double-clicking the X3F data or drag-and-drop of the image file directly on the software’s icon.
  • It has corrected the phenomenon that it occasionally fails to open the print window and preview window for printing.

For Mac

  • It corrects the issue where the message suggests the operation of “lldb command tool” or inserting password is displayed either when the working color space is set to Adobe RGB and 100% enlargement is performed or when the application is closed using a short cut key.
  • It has corrected the phenomena that the operation speed of the software slowed down in some occasions and took a long time to open folders.

Sigma 18-35mm f/1.8 DC HSM Art

The Sigma 18-35mm f/1.8 DC HSM Art is not a new lens (the Canon-mount version was released a year ago), but Sony and Pentax users wanting one have had their patience stretched by multiple delays. Now it is finally available for everyone.

The stores where the lens is in stock as I write these lines are listed below.

Sigma 20mm f/1.8 EX, 24mm f/1.8 EX and 50mm f/2.8 EX Macro: Discontinued

Sigma will no longer manufacture the 50mm f/2.8 EX DG Macro, as well as the 20mm and 24mm f/1.8 EX DG. The whole trio of fast wide-angle lenses is now discontinued.

What is Sigma cooking up to replace them?

20mm f/1.8: Sigma may come up with a weirdo. We have heard about 16-20mm f/2 once. Just like with the 18-35mm f/1.8 Art, there may be several patents (here, see last paragraph), each one showing a different concept (ie. with different zoom ranges).

24mm f/1.8: A 24mm f/1.4 Art is supposedly not so far off.

28mm f/1.8: Not a priority. Nothing to report here as of yet.

Sigma releases SPP 6.0.1

Sigma has just released the first update to Sigma Photo Pro 6. They say:

It has fixed the bug in the Overexposure Correction function of SIGMA dp2 Quattro.

More (important) details:

  • Windows 7 and Windows 8 (64 bits) users have to make sure the KB2929755 update is installed prior to installing SPP 6.0.1. KB2929755 can be found here (Win 7) and here (Win 8). I cannot install the update myself (not applicable to Windows 8.1?) so I cannot tell whether it solves the TIFF/JPEG saving issue, which is still there with Sigma Photo Pro 6.0.1. Sometimes, the error window does not appear, but in any case, the file is not recorded, or is empty (0 byte). Please feel free to share your experience in the comments.
  • Mac users who work in the Adobe RGB color space may want to take a look at the issue described on this page, but it is of little relevance if you do not have the dp2 Quattro. Why? Well, Sigma invites you to use SPP 5.5.3 for processing X3F files taken with SD1 or DP Merrill cameras.
  • Good news: Sigma Photo Pro 6.1.0 will support all Sigma DP and SD models.
