    Loren, Scott
    I just wanted to thank both of you for taking the time to read and respond. I switched out to a Sigma 15mm fisheye. On initial test of this lens, I get the clean crisp sharp photos I am looking for and it works great with my Nodal Ninja. Again, thank you for your input which sent me in the right direction.

    Scott,
    Thank you for the information and feedback. Once I get a lens that I feel confrontable in using I will verify the NPP, it is funny that you bring that up, I was just read thru the instruction on NodalNinja Ring rotator and they point that out. They show a fine adjust just for that. I finally understood what Sigma tech support was talking about. It was like we were speaking two different languages and basically we were. Once I understood what they were talking about and a few other recommendation the 8mm lens will not do what I need and the tech gave me a few recommendation and one was the Sigma 15mm, that being said I am trying to rent a Nikon 10.5 to see if it is what I like prior to purchasing, but also looking at the Sigma 15mm. Again thank you for all your help and input.

    On a side note I know I do not post on here a lot but I read a lot of the posting, I just don’t see as many anymore. Any ideas why not?

    Scott,
    To address the point you spoke of NPP, no I a not try to determine or adjust for that. I am using a Nodal Ninja ring clamp and rotator. So I do not need to calculate that, the rotator handles that. The calibration I am speaking of is the actual focus plain of the lens on the camera. I did not know this prior to buying this lens because I never had a focus issue with any of my previous lens or camera bodies. After seeing the results of this lens and doing research I found both my Nikon cameras have the ability to adjust the focus plan slightly in the tools option on the camera body. Like I said I never had to do this and after research bought a Vello lens focus calibration card. Instruction say crank up the F stop to maximum F stop in my case F22, the though process is to reduce that plain to the smallest distance so you make a slight adjustment in the camera body to accomplish this and achieve the best focus with slight adjustments for the specific lens. What I found in doing this was the camera body said I was in focus on the flat plain of the Vello card at about 1.5-2 feet. But I was out of focus when looking at the picture scale and was not even close to even being able to make an adjustment in the camera. I sent that photo to Sigma but also did what you suggested and sent a photo at normal settings and showing them the way I used the lens with standard setting I normally use. Both photos were out of focus in my opinion. When I spoke with Sigma I was not trying to be critical but asked the person writing them were they apart of customer service or technical team. They responded with they were with the technical service team and pointed out they still did not feel there was an issue with this lens. That was because I said I wanted to still send it in for review. He indicated that I would basically be wasting my money. Since I never had this issue with any other lens I was caught off guard and am going to rent a Nikon 10.5 fisheye to test it prior to purchase. Unfortunately I am getting a little to old to continue to use a manual focus lens. So even though I think the other lens you spoke of is an option I am not sure if my end result will be any better than the Sigma and one of my goals is a total setup that allows me to get a camera, lens and rotator for me that produces a top notch product/picture but be able to accomplish this as fast as possible. In my opinion the Ricoh Theta Z1 gives me that speed but again not the quality I am looking for. So again thank you for your input and probably way more than you were looking for. I guess bottom line is I see a lot of photos by members of this forum with great photos so I know it can be done, like I pointed out whom ever took the photos for krpano depth sensor show case a good setup to do this. I think it can be done I just have not found the complete setup yet. So again other than the focus issue if anyone has input on a DSLR setup that work for them I would love to hear about.

    Thank you again
    Ron

    Loren, to address your question on what I consider clear and sharp, if you look at KRPano tour of the depthmapping I consider that to be clear and crisp. I also agree that there should be reasonable expectation of clear and crisp.

    Scott, I did try to sharpen the image in lightroom, for me it was still soft. I know it can be done and like I pointed out I am trying to balance out speed and quality. I will look at the 10.5mm lens. Just frustrate, but like you pointed out I believe the culprit is the lens. I guess my frustration is with Sigma’s customers service, they said the lens was not designed to be used at F22. As I explained to them the F22 setting was an attempt to calibrate the lens not a general use setting. Scott at this point I must agree that the Sigma 8mm quality as presented by their customer service is not the quality I would expect or accept, even though they think it’s ok. Sad to say I am normally a Sigma lens supporter, I get excellent results from my 10-24mm or 70-210.

    Thank you both for your input.

    Great Quebec360 shot, if you do not mind me asking what camera you used and if it was a still camera what mount did you use to get the panoramic and what software did you use.

    Thank you

    I am new to the forum and just stumbled across this link and this software is phenomenal. I hope the programmers are still following. I have a few questions about your product.
    1. I saw that the one example was a lower quality panoramic and I saw the one on your webpage was higher quality is there a limit on the file size? Can higher quality larger files be downloaded?
    2. Where are the tours hosted?
    3. Is the final product cross platform compatible?
    I like this and I am very interested in your product. I am sorry if this has been covered and may have been covered.

    Thank you
    Ron
