Pentax DA 40mm and 70mm Limited lens review, tested with Pentax K10D
Written by Gordon Laing
The following images were taken with the Pentax DA 40 and 70mm Limited Edition lenses, using the Pentax K10D. Unless otherwise stated, each image was recorded using the K10D’s JPEG 10M *** mode and sRGB colour space, with Auto White Balance, Multi Segment metering, Natural Image Tone, and Sharpness, Contrast and Saturation set to their zero positions. The individual file size, exposure mode, shutter speed, aperture, ISO and lens details are listed for each image.
The crops are taken from the original files, reproduced at 100% and saved in Adobe Photoshop CS2 as JPEGs with the default Very High quality preset, while the resized full images were made in Photoshop CS2 and saved with the default High quality preset. The three crops are typically taken from far left, central and far right portions of each image.
