Here's a brief look at the Sigma 10-20mm F/4-5.6 EX DC zoom lens. Scroll down for the review.
For instance, the previous Sigma 10-20mm lens has a variable maximum aperture of f/4-5.6. So, this newer lens is a significant improvement. Maximum aperture of the Sigma 10-20mm f/3.5 EX DC HSM is complemented on the other end by stopping down to f/22. Stopped down and zoomed out to widest angle, there is an amazing deep depth of focus. Dec 06, 2017 In this video we'll discuss the three best lenses for real estate photography and video. I'll simply breakdown why we use each lens and how they are important for our gear. Gear mentioned: - Canon.
Using the DX lens on the FX body in cropped mode will give you something like you are getting on the DX body but you are throwing away lots of FX pixels. If you use the 10mm-20mm a lot you may be disappointed. At least you can use the DX lens on the FX body until you can afford to purchase the equivalent FX wide angle zoom. Alan, in Montana. Vickie in TN asks: I am struggling with choosing a suitable wide-angle lens to use with my Nikon D4. Being new to real estate photography, I hesitate to purchase the best/most expensive just yet. However, I am not confident that I can get by with my 24mm. When I browse real estate listings, I see. Sigma 24-70mm f/2.8 DG HSM Art. The all-round best Sigma midrange zoom lens.

Aperture/focal length guide for the Sigma 10-20mm F/4-5.6. This lens has overlapping numbers, depending on tiny movements of the zoom ring, this is quite common. Look below for guide. Also, this lens did not register 14mm in the EXIF data, which is the same as the Sony 11-18mm. So why do they put 14mm on the barrel? Also no 19mm, but that's no problem.

Range | 11mm – 13mm | 17mm – 20mm |
Moderate barrel distortion, 10mm |
Barrel and pincushion distortion. The distortion at 10mm-11mm is odd mustache type, hard to correct in post processing. There is no flat point in the zoom range, and pincushion starts around 13mm. The Sony 11-18mm is better at controlling distortion. In landscape shots, this distortion rarely shows up unless you're shooting straight lines near the image edges. A workaround for the mustache distortion is to zoom out to 11-12mm for architectural type shots.
Lens Bokeh. Manual book ht alinco dj 196. The Sigma 10-20mm F/4-5.6 is just so-so to harsh in this department. Generally, everything is in focus less than 15′ (4.5m) and beyond, so background blur isn't something I'd worry about with this lens. See crops below.
