    New Sigma 150/600

    Here are some shots taken with the Nikon D7200. I changed from D750 to D7200 because I almost always cropped the D750 down to 10mp which equals 1,5x crop. So now I get 24mp without cropping much. A bit more noise but who cares? :D I have gone through my regular web-post processing on these...

    New Sigma 150/600

    As I wrote earlier I also had really sharp images mixed with soft ones. Now after af adjusting all the distances it is sharp sharp sharp!

    New Sigma 150/600

    Today I took the sigma through some calibration. I calibrated all focal lengths and focal distances except the infinity one. Frankly I don't know how to go about measuring if infinity is in focus or not when not even the moon is at infinity. Besides I never shoot at infinity anyway. The...

    New Sigma 150/600

    So, today I have shot some more at different distances and shutter speeds. I think I now have pinpointed down my problem with blurry images. I think I have a case of front focus at some different focus distances. For example up close I get consistantly very sharp results where the focus point...

    New Sigma 150/600

    Nice pictures guys! I was out today to try out the new settings on the lens. Works like a charm. I even got a handheld shot at 1/30 of a second at 600mm with slight winds :eek!: Nothing I would do all the time but it worked. I didn't encounter any issues with higher shutter speeds and OS...

    New Sigma 150/600

    If they wanted to they could stabilize it one way before the trigger is pressed and slightly different just before taking the picture. But that would induce some kind of lag in the shutter. Just saying it is possible, but you are right it is not logical in this case.

    It certainly would be possible. In this case though It does effect the picture taking.

    New Sigma 150/600

    Alright I have now tried some different settings on the usb dock. I think you are correct in your findings the black fox (Jeff?)! The viewfinder is much easier to hold steady with the dynamic mode activated. I also activated the accurate settings for AF point. I will try this out this coming...

    New Sigma 150/600

    You are totally right about the distances but as you say the quality should be a bit better. I will get back here when I have tried out your settings through the usb hub :)

    New Sigma 150/600

    Looking good, although I never had an issue at lower shutter speeds really. And close subjects work good too. I think longer distances and faster shutter speeds together with OS doesn't work 100%. This could be down to poor technique from my side of course. I'm gonna have to try some more with...

    New Sigma 150/600

    Yes I understand that you reprogram the lens through the usb hub. But my question is if the OS settings effect how the lens stabilizes during shutter release or just how the lens stabilizes the viewfinder before taking the shot. I read a review stating that in fact the OS settings in the hub...

    New Sigma 150/600

    I read your findings earlier but haven't had time to try it out since I don't have the usb dock yet. I will pick one up tomorrow and give it a try. But from what I understand the different OS settings in the usb dock only effects the viewfinder and not the OS function when taking pictures?

    New Sigma 150/600

    I bought the sigma 150-600 for nikon a couple of months ago and I had the Tamron before. The Sigma is the better lens in everything except stabilization I would say. I might just be lazy but the tamron stabilizer worked with whatever shutter speed i used handheld. It did take a second to...
