ZEISS Milvus 18mm f/2.8 Full Frame Camera Lens for Nikon F-Mount ZF.2, Black

I wanted to test this lens against the fantastic zeiss 15 classic before posting a review, I will say I am very excited to have this lens in my arsenal.it holds up nicely against the 15mm in micro contrast, sharpness, and excels over the legendary 15 in, flare control, shooting into the sun, portability, and the ability to use the 100x100 lee filter system. I also enjoy the focal length in that it is between the super dramatic wide angle of the 15mm yet still wider then the ideal landscape focal length of the 21, being the sweet spot for me if I only want to carry one wide angle. saw couple negative reviews on the internet on this lens though I am not seeing any negatives, it also makes excellent sunstars, I am going to test it out on stars tomorrow night as the weather clears and am feeling confident in its abilities. my only gripe is that it IS NOT HARD STOP as advertised and if you expect zeiss lenses to be at had stop AS ADVERTISED your fooling yourself. you would think that zeiss would have it together enough to deliver what they claim but it took me 3 15mm distagons to find one with hardstop, (meaning focus ring stops at infinity focus), come on ZEISS get it together. If I did not love there glass so much I would not still buy from them, my 21mm came needing a new cpu chip? my 15mm came with a sluggish irish and still needs to be repaired? am I a sucker or what! I have never had a problem with a plastic nikon lens. though when you get a zeiss kit that is working it is pure heaven and life changing.
