Sigma 18-50mm f/2.8 DC DN Listed at PhotoWarehouse

By Louis Ferreira | Published: November 4, 2022


We have waited for the Sigma 18-50mm f/2.8 DC DN for a while now, and it was supposed to be for sale in April of this year, but Sigma later changed it to by the end of the year. Now that the end of the year is upon us, PhotoWarehouse has listed the Sigma 18-50mm f/2.8 DC DN, and you can read all of the details below:

Details for Sigma 18-50mm F/2.8 DC DN Contemporary Lens For Fuji X-Mount
Ideal for a wide range of photo and video applications including landscapes, portraits, street photography, architecture, and events, the 18-50mm f/2.8 DC DN Contemporary Lens from Sigma is a small, light, and bright standard zoom for crop-sensor mirrorless cameras. Offered here with a Fuji X-mount, this lens provides a versatile full-frame equivalent zoom range of 27-75mm and a wide constant aperture of f/2.8 throughout the entire zoom range. The lens design includes three high-precision glass-molded aspherical elements coupled with a special low dispersion element. Together they minimize the total number of elements for superb optical quality without excessive weight. Autofocus is exceptionally fast and quiet thanks to the lens’s stepping motor, which can be particularly useful when shooting video or fast-moving subjects such as children and animals. An ultimate workhorse, the lens features a minimum focusing distance of just 4.8″, enabling it to be used for macro-style close-up photography, and the lens is also outfitted with a rounded seven-blade diaphragm for a pleasing bokeh quality.

Standard zoom lens is designed for Fuji X-mount cameras and provides a 27-75mm equivalent focal length range.

Constant f/2.8 maximum aperture is well-suited for working in low-light conditions and provides greater control over the focus position when using shallow depth of field techniques.

Three high-precision glass-molded aspherical elements are used to help limit distortion and spherical aberrations and contribute to greater overall sharpness and accurate rendering.

Special Low Dispersion (SLD) element reduces chromatic aberrations and color fringing.

Super Multi-Layer Coating minimizes flare and ghosting for improved contrast and color accuracy when working in strong lighting conditions.

In-camera aberration correction further eliminates optical imperfections such as distortion and vignetting.

Stepping motor with nearly silent autofocus that makes it perfectly suited to a range of photographic applications, including shooting in quiet environments, recording videos, and capturing fast-moving subjects.

Minimum focusing distance of 4.8″ and a 1:2.8 maximum magnification ratio benefits working with close-up subjects.

Rounded seven-blade diaphragm contributes to a pleasing bokeh quality.

DPR: Fujifilm X-T5/X-H2 Studio Scene Posted But DPR Can Do Better

By Louis Ferreira | Published: November 3, 2022


Fujifilm X-T5 Black:

Fujifilm X-T5 Silver:

Fujifilm X-H2:
B&H Photo / Amazon / Moment / Adorama

DPReview has been around for a long time, and many photographers use their studio scene tool to compare cameras, which is why it is convenient that DPR posted its Fujifilm X-H2 results, but they are also claiming the results should be identical to the Fujifilm X-T5, but there are a few problems.

For one, Fujifilm made a big deal about the Fujifilm X-T5 being photography centric, so there is a good chance Fujifilm tweaked the sensor/processor performance since the features of the Fujifilm X-H2 and X-T5 are very different. DPR also used the old XF56mm f/1.2 for the test at f/5.6, which isn’t one of Fujifilm’s 40MP compatible lenses.
