NX300 with Jupiter 37A MC 135mm f3.5

I wanted to get a lens to use to shoot my dogs (that didn't come out right :)) and originally planned to get the NX 50-200mm, but I wasn't sold on image quality when zoomed out. So for a fraction of the cost (45USD, around 40 euros), I got an old Russian Jupiter prime lens to try to use it as a manual lens on my NX300. It's praised for good colors, decent sharpness and nice creamy bokeh and 135mm sounded like the perfect length to get good shots from ~10 meters.

It's my first weekend with it and I'm still getting used to manual controls. It's a bit heavy, so holding the camera, playing with focus while holding OK key to get focus peaking to work and firing the shutter is a lot to do at the same time Next time I'll take the tripod with me, it should be a bit easier.

Either way, I'm pretty happy with it. It lived up the expectations. I shot all these at f4 with ISO 400 trying to keep the shutter speed above 1/200. Wrestling with the focus and focus peaking button and shutter button makes my hands shaky, so wanted to avoid hand shake blur. That should also improve when using with the tripod, so I should be able to get less noise, although it's not too bad with ISO 400. Sure, having auto focus would help tremendously, but I doubt I'd get better images at 135mm using the 50-200mm lens. There is some light post-processing done in LR, corrected colors and exposure and removed a bit of that noise.

Btw, these are not the typical "cute dogie" kind of pics. My folks are breeding Rottweilers and for the website they need to showcase dogs in certain poses that aren't typical pet poses
