ProMaster 70-300 lens

This lens is a rebadged Tamron. I bought this used, and have been very surprised at how good it is! All of these photos are with a Tamron 1.4X TC, handheld, and cropped. If you get a chance to pickup a ProMaster, don't hesitate; I paid $65 for this gem!

I got a Promaster and film body for next to nothing, it's a 28-105 and really quite nice. I'm sure it's not as durable as the Pentax offerings but impressive.

I have a Tamron I should sell. It worked well enough, quick to focus and accurate. On the K10 it was good, on the K5 it was a purple fringe monster. I haven't tried it on the K3II - I suppose I should, just to see how it works.

Yes, I just received the 28-105, haven't had much of a chance to play with it yet.

Here's another handheld; K3, ProMaster 70-300 +1.4TC, cropped. Not wild about the Bokeh, don't know if it's the lens, TC, or combination; but other than that, really love this lens.

I have had the 28-105 with the Promaster Badge and three with the Tamron Badge, I still have one Tamron and my daughter has the Promaster. An excellent lens, quite a surprise, but with the plasticy construction I'm there there are beater copies out there too.. When you see your exif don't be surprised to see smc PENTAX-FA 28-105mm F4-5.6 [IF] because it was also rebadged as a Pentax. Not sure why Pentax offered three different FA 28-105 versions at different times. .

To me, it seems to be a rather hefty little lens; I don't see/feel a plastic construction like I've experienced on some "real" plastic lens.

Thanks for that EXIF info, that's interesting!

Carol, I have had this lens since my K100D and never had any issues with the build or the images. Got it so I could shoot marching band pictures of our son from waaaayyyyyyy up high in the Iowa State U stadium. Still have it today, I use it on the K-50 when I need a bit more than the 18-135 can provide.

Thanks Jim; I'm really impressed with the ProMaster line; but I've been an avid Tamron user also, so I shouldn't have been surprised at how good this lens is!

I'll add a pic, then. This was taken with the K100D, indoor with ambient stage lighting. I did have it on a monopod at the time. ISU band in a concert setting - the kids' favorite band director "Mr K"...

I don't recall what PP I did other than cropping and resizing, probably some sharpening, but that's about it I think.

What a great capture! I've noticed outside of cropping, I have done little PP using this lens, also!

Happened to look out the window to see this hawk. Images have been cropped so that the bird he was eating was not visible, for all bird lovers, including me! Anyone ID this bird?

A Cooper's or Sharp-shinned. Hard to tell the difference without seeing the end of the tail. Even then...(Square tip vs. rounded tip, head size etc.) The head on this bird looks small to me, so I would say Sharp-shinned.

Thanks! I also think the Sharp-shinned because of the markings on the head. His tail was always behind something so I couldn't get the full view of him.

Thanks for the link also; I've bookmarked it. I have several books on birds, but very difficult at times (like this one) to nail down the species.

The moon looked so great that I decided to try handholding the 70-300 +1.4 TC.

This lens combo does well on landscapes also.
