![]() Personally, I do prefer to keep this level of sharpness and contrast in the corners at the cost of a little less linearity. What other shortcomings? Look off-axis to the left and you will see good detail in the "Kimmberly Capone" storefront, and through the store windows into the interior of the store itself. Unfortunately, the difficulties of making such a wide angle lens for a 1/2.3" 4:3 format digital colour sensor, and fitting it in the constraints of an M12 mount mean that "something's gotta give", and in this case, the designers felt that this much distortion was preferable to other shortcomings. Even today, if I bought a prime wide angle lens for an interchangeable lens camera, I think I would be looking for less than 1% distortion. We generally felt that a rectilinear wide angle lens (or any rectilinear lens) should have less than 1% distortion. Is that "rectilinear"? I mention my old equipment because back when 35mm SLR film cameras were commonly used, 4% distortion would not have been acceptable to most photographers. The only lenses I have wider are not considered rectilinear.īut this lens claims under 4% distortion, and that is about what it looks like to me. The Samsung Galaxy Zoom EKGC100 at about F21mm is the widest non-fisheye lens I currently use, and this Git2 lens matches that camera almost perfectly - right down to the barrel distortion. I do not recall ever having a movie or video camera with a lens wider than 35mm SLR equivalent F35mm before my recently bought Sony CX240B (about F30mm equivalent). That was a Soligor f2.8 which probably costed $100-$150 Cdn., but it performed well. I could have set it to 1 image for every 2 sec., but I actually like working at 1 image per second because I changed the composition a few times (re-pointing and leveling the camera), and it is harder to make such changes with the longer delay between pictures.īack, around thirty years ago, I never had a wider lens than a 28mm on my 35mm SLRs. The result is that the battery drained down faster than it would in a true "carefully set up" time-lapse set. Also, I kept the display ON in order to evaluate the lighting changes and composition on the fly. I stopped the time lapse series at three points because the lighting changes were slower than I anticipated. ![]() Now that I know that WDR made no difference for still pictures, I am glad I did not waste my time taking the control pictures. But the cold weather (-6 deg C) combined with wind gusts made it too cold for me, and I decided not to try making the cell phone pictures. ![]() My original plan was to set the Git2 on a "hand-pod" on top of my car (to avoid being conspicuous and drawing the attention of Mall Security), and to take "control" images using a cell phone to compare the effect of the Git2 "Wide Dynamic Range" setting. "Time Lapse" was set at 1 file per second. Metering is Center Weighted Average (which is correct). But then again, they list the focal length at 3 mm (incorrect) and F-stop as f/1.8 (also incorrect). According to the EXIF 2.2 file header, the (automatic) exposure was 1/30 sec. I set the image size to full 16MB which is a 4:3 format with 4608 x 3456 pixels. As noted above, after this project I upgraded to the 1.6 version firmware for the Git2 and it now supports "contrast" settings (high, medium, low) individually for video and still, as well as continuing support for WDR in video. However, it might work for a Video based time-lapse which is a different capability. The WDR setting only works for Video and so the setting does nothing for a Still photo based type-lapse. Unfortunately, this was something I misunderstood. To keep the exposures within a useful range, I thought I would use the WDR feature on the camera. ![]() NOTE: I updated my camera to 1.6 version firmware after this project was completed. I decided to use my "new" GitUp Git2 camera with its rectilinear 4.35 f2.8 lens, and version "GIT2_V1.4_0324" firmware. In general, I thought that a time-lapse series taken from about 16:50 - 17:10 would be give me good variety. The mall was open, so traffic would provide a changing foreground composition, and lighting would be changing as the sun went down and artificial lighting came on. I thought that the evening lighting, around sundown could be interesting to photograph. The new north face of the building features large windows in the upper floors including two display windows per floor, and new glass doors in the entrance. ![]() Recently the "Hudson's Bay" store at Yorkdale Shopping Centre in Toronto was renovated. ![]()
