  1. NN3 with Pentax K5

    #1

    Hello,

    I currently use an NN3 mk2 with a Panasonic GH2 and 7-14mm lens. I have started thinking about moving to a Pentax K5 with either a Sigma 8-16mm or Pentax 10-17mm fisheye.

    Does anyone know if the above would work fine with the NN3 in terms of size for 360 VRs?

    Thanks.

    Pentax K5 with Pentax 10-17mm fisheye should be fine. not sure about the sigma.

    Hi LeChuck,

    I've got a Pentax K5. I'm using it with a Samyang 8mm f/3.5 and a Samyang 14mm f/2.8. Here's an example taken with the Samyang 8mm and a NN5: http://www.360tacticalvr.com/blog/?p=218

    I'll check today for you if you can use the Samyang 8mm with the K5 on a NN3. You can't use the 8-16mm Sigma with the NN3 and the K5. Yes, you can use the Pentax 10-17mm and the K5 on a NN3.

    Thanks for the info! The 8-16 looks intresting, but not as much if it requires changing the pano head, which adds more weight and volume.

    Samyang 8mm works with NN3 and Pentax K20D, so it should also work with the smaller K5 body. Another possible lens is the Sigma 10-20mm f/4-5.6 if you want higher resolution than the Samyang fisheye gives.

    Have you tried stitching with a Sigma 10-20? This is the orientation I might take, replacing the GH2 + 7-14 with a K5 plus Sigma 10-20, which doesn't seem like a too large increase in weight. I'd prefer a small 10mm prime but I don't think there is one. There seems to be good correction in Lightroom for the Sigma lens.

    Currently with the 7-14mm on the GH2 I can do a 360 very well with 6 shots around at -30°, 6 shots at +10°, one zenith, plus what is needed for the nadir. That's in 3-4 picture mode. I'm wondering what I could achieve with the 10-20 on the NN3, hopefully not too many more shots if any. The field of view on the 7-14 at full wide is a bit wider than on the Sigma at 10mm, I think 114 - 75 and 111 - 72. One difference is the pictures would now be 3/2 ratio instead of 3/4, which most likely means less width coverage and might require 8 shots around instead of 6...

    I do not want to use a fisheye at the moment because I want to make panoramas that will also make good flat fine art prints and want a bit more resolution, but without taking a lot more shots than I do now, not gigapixel stuff. So, a good compromise.

    Yes, for results see e.g. http://www.panoguide.com/gallery/2184/ or http://www.panoramio.com/photo/42944106
