Weather Underground Blackstone Va

I was returning to photograph a derelict house and wanted a lens�wider then the Zeiss 21mm I used for interior shots on the first trip.� I own the NIkon 14-24 f/2.8 but was wondering if there was a better option. I read a good, short review of this lens by Thom Hogan on bythom.com. The lens did not disappoint in any way. The build quality and attention to detail are top notch. Optical quality is better than expected. I was able to square up the interior shots and the resulting files required no correction in post processing. Color and contrast are up there with the best. I look forward to using the lens on Milky Way and star shots in August and landscapes in June.� I contemplated the Blackstone versus FIrefly and decided on the Blackstone for the nominal price difference. I would not hesitate to recomend the Firefly for a tighter budget.

I ordered the blackstone version of the lens after hearing the positive reviews associated with the lens when it was originally announced several months ago. I have used the lens dozens upon dozens of times since purchasing and I have been nothing short of 100% satisfied.� SHARPNESS/QUALITY: For nature photography this lens provides very sharp images with only the very corners being slightly softer wide open. When stopped down to b/t f/5.6-11 the sharpness is nothing short of perfect at any distance. The distortion and chromatic aberrations produced by the lens are well controlled and less significant than other ultra wide lenses that are far more expensive FOCUS: Focusing is so simple for landscapes as setting the lens to infinity will maintain ideal focus on any object further than 10 ft distance even at f/4. Focus was near perfect when it arrived on my D750 and required no adjustment.� BUILD: The build is top notch and I have no complaints. Feels as tough as any pro level lens. The focus ring is very sturdy and smooth so I have never had the focus slip, I rarely use the focus lock for that reason. Weather proofing is enough to keep rain from penetrating the barrel. I have included an image I took recently with the IRIX 11mm at f/8.

I've had my 15mm Blackstone for 4+ months, and have been very happy with the lens for astrophotography. The copy I have, has proven to be very sharp across the frame. I'm a retired professional photographer (always Nikon), and the build of the lens is excellent. It is manual focus, but the handling is very smooth, and it feels well machined. I could only do better, by spending at least $1,000 more.

I bought the blackstone and the nice integration with the Pentax k1mk2 and SR makes it a winning combination. Optical quality is tremendous for this cost of lens, the way it handles is really really nice. Focus ring is not to stiff or to loose, just right. Focus lock is a nice feature and the minimum focus distance is 1 foot. Pretty amazing for tight perspectives in the industrial work I do

i donated it to the VA Domiciliary at Ft. McPherson

Great vest. I'm using it in an underground coal mine. It's like having an extra pair of hands. It distributes weight evenly. I use it for batteries, flashes, all sorts of accessories. There are no pockets for big lenses, but that's O.K. It would make the vest too heavy and cumbersome. It's pretty good at repelling lime and coal dust and water and is not likely to tear easily. Pockets are lined with soft material, which is easy on lenses. These vests are a little pricey, but worth it. They're professional gear and are made for rugged use.

Solid takes abuse perfect for poking the gopro into strange places underwater and underground.

So far so good! Using as a backup power supply for an underground dog fence and so far is working great.

We mostly use it to protect our lens for our camera at work, being as we drag the camera through steam tunnels, in mud trenches, inside underground vaults, and through all sorts of other environments. The filter screws on firmly to the end of the lens and protects the lens from scratches, dirt, dust, etc. without distorting any of the pictures.

I use 50+ of these routinely for delicate electronic sensors that are buried underground in very wet Florida environments for over 6 months at a time. I love the color-changing pattern on the exterior of the pack that let's me now when it's due for replacement or refreshing in a microwave. I used to use the metal type that needed to be baked for 3 hours, but those too long to replenish and were small in comparison.
