In the US, the term off-brand means a minor brand or a brand that is re-labeled for a particular store. For example, Ricoh (a minor brand for most of its history) was sold under the Sears name at the Sears store and under the Focal name at the K-mart store. Rikenon, Sears, and Focal are all considered off-brands. Some lenses are considered off-brand just because they were made in limited quantities and/or were not widely sold outside their home markets. Often the off-brand lenses are quite good as you can see from some of the examples posted on this thread. The cool thing about the off-brand lenses is that aside from the various collectibles (Revuenon, for example), they can often be purchased for very little money and represent the potential for a lot of fun and experimentation.

Posts: 138 | Let me add an interesting "tid-bit" regarding Promaster......I picked up one recently for a beach vacation. Didn't want to take my nice glass. Looking over my Exif data, it shows the promaster 28-105mm zoom as "SMC Pentax-FA 28-105mm F 4-5.6 (IF)" Interesting as I always thought promaster was supposed to be re-branded Tamron. Oddly enough, the lense still produced some nice shots that I posted elsewhere on this forum. Maine... Mark |

On the other hand, the Exif data might be a little suspect. I have a Sigma 50/2.8 Macro that codes in the Exif as a Pentax D FA 50/2.8 Macro. That would be a happy surprise if it were so, but alas the fairies did not transform my Sigma during the night.
 Your Maine shots are pretty incredible, by the way. Looks like you made an excellent purchase! Steve Last edited by stevebrot; 07-06-2008 at 03:51 PM.. |

According to this site's Pentax lens review database (click here), the Pentax lens was made by Tamron. So the most likely answer is that both lenses were manufactured by Tamron and rebadged as was appropriate. The Exif is a correct from the perspective of what lens was on the camera, though the brand label was a case of mistaken identity.

If I remember correctly, Kitstar was a house brand for Kits Camera before they were purchased by Ritz. Steve |

| Pentaxian | I have some el cheapo DOT close up filters ( +1, +2 and +4 ) . Does it count if I put it on a Pentax lens ? I tried them on FA50/1.4 which is not " cheap" but not too much expensive either . The Focal 90-410/4 does not have a filter thread ! M42 in my case . |

  A few more images....no sharpening added. Just some cropping, saturation, contrast, levels/curves, and resize. @f2.8    @f4  @f8  Last edited by maxwell1295; 07-07-2008 at 12:30 PM.. |

| Loyal Member | Steve, The build quality of my Soligor lenses is very good and equal to Pentax M42 in this respect. The IQ varies according to who made the lens for Soligor and the original cost. My 70-220mm f3.5 C/D zoom is a good performer, although heavy at 3lbs. It does have a tripod mount and is all internal for focusing and zooming. I have a couple 35mm f2.8, T4 lenses that are decent, but they aren't the cheapest Soligors either. It is easy to trash a lens, but you should try one first. Dave Originally Posted by stevebrot

| Site Supporter | Like Vivitar, Soligor made some good lenses and some bad ones. It all depended on who the original manufacturer was. I had a Soligor 24mm/2.8 lens that was of very high quality. Built like a tank and produced some pretty good images. I just didn't like metering with it, so I ended up letting it go. I much prefer "A" lenses or M42 lenses that can be used in Av mode. |

Posts: 2,695 | Yashinon 35/2.8 (screw mount)  Click on the image to view it in a larger size  Click on the image to view it in a larger size Vivitar TX 28/2.5 Close Focus:  Click on the image to view it in a larger size  Click on the image to view it in a larger size  Click on the image to view it in a larger size OK so Yashinon and Vivitar aren't exactly unknown brands, but these particular lenses aren't well known at all. |
