While researching mirrorless digital cameras, I was drawn into the Samsung NX1's orbit by the camera's fresh digital interface; intuitive operational modes; lens adaption possibilities; interval recording and impressive filmic motion imaging. Importantly, many photographer's reviews said the NX1 was a joy to shoot with. This blog will document my intention to become a better 'still' photographer; but the NX1's primary function for me will be digital-film imaging. Feel free to comment.

Quantaray 28-90mm F3.5-5.6 Lens - A Surprise
I picked-up this Quantaray 28-90mm F3.5-5.6 Lens at a record store in Phoenix, Arizona that also sells used music equipment and some electronics. The QUANTARAY name was unfamiliar to me and normally I collect lenses from the 1970's and 80's, yet this one looked like it was from the 90's of early 2000's with a hard plastic material; so I was hesitant to buy at first.
But I was curious and I liked the sweet-spot focal length range of 28-90mm (42-135mm equivalent on the Samsung NX1). The price at $25 wasn't bad, the lens was made in Japan, easily adaptable Pentax mount and overall the lens was in really good shape. So I picked-it-up.
An Internet search reveals very little about this lens. But it appears that the lens is manufactured by SIGMA and distributed exclusively by Ritz Camera (.com) at that time. I went to ritzcamera.com and it look like they still sell (new) Quantaray lenses.

The photos posted below were 'as-taken': No post editing or effects. Note that after taking these photographs I went back into the in-camera settings and notice I had the 'VIVID' picture effect turned 'on'. This had the effect of increasing saturation and contrast. Sorry I didn't write the f-stop setting for these photographs. Camera was in manual shooting mode and with the lens adapter, the f-stop setting is not recorded to the NX1's meta-data file.
The above picture was taken with house lights only at an ISO of 6400 - Impressive
I took this photograph for an artist who wanted a quick-photo inventory of her stained-glass work. I used it as an opportunity to play with the Quantaray. In order to avoid a street scene and buildings in the background, I got on the floor and shot-up at the glass pieces attached to the store's window. The plywood in the background is looking-up at the porch overhang.
Nice shot of translucent calcite cylinders illuminated by indirect light. Notice the smooth background bokeh. Sorry,I did not record the f-stop.
Other notes: Despite the lack of information on this lens online, I did come across a forum discussing this lens. I think this lens is fantastic and thus was surprised to see postings that it was a good lens at $30 but would be disappointed at a higher price: Or, that people considered it a beginner's lens.
Also, This Quantaray's focus ring at at the front of the lens. I noticed during my test shots that the len's optimum focus point was tight (in other words you are either spot-on or you fall-off. Thus, thank goodness for 'focus peaking' on the NX1 to nail it.
