In Topic: Nikon Mirrorless cameras - Z6 and Z7

I am not sure who that level thing on the EOS R will be implemented but I am sure ISO could be reached from the super screen or what ever they are calling it. Canon has taken a very different approach to mirrorless than Nikon, I was a bit surprised that they did not offer IBIS in stead on in lens stabilization. 

 

Regarding mirrorless lenses it appears that the difference in the setback between mirrorless lenses and DSLR cameras with the mirror makes a difference in the size of the port needed for wide lenses. Example Nauticam recommends the 250mm port for best results with the Canon 11-24 F/4 and the Nikon 14-24 F/2.8. For the Sony 12-24 F/4 the 230mm port is recommended for best results. While Sony 16-35 F/4 & 2.8 can be used with ports as small as 180mm. So apples to apples on full frame Sony at 12mm behind 230mm dome should yield the same corner sharpness as Canon at 11mm behind the 250mm given the same F/stop. 

 

The prevailing wisdom is that Nikon D850 and D500 have the fastest and most accurate AF of any of the DSLR's and that Sony has the best for any of the mirrorless cameras. I Shoot the 12-24mm in AF-C most of the time and I do not own a focus gear for the lens, in fact the only focus gear I own is for the 90mm macro and I would be hard pressed to say the last time I have used it. Like all full frame cameras I try to shoot at F/13 or higher unless I am looking for shallow DOF. This is one tradeoff for shooting FF. Keep in mind that I am not a video guy so my observations are based on stills. The high end Sony lenses are excellent which has been proven by tests by DXO and others. Also regarding the larger lens mounts selected by Canon, Nikon and Panasonic I understand the concept for faster lenses but the smaller Sony mount seems to be fine for any lens I would use and you can find a bunch of lenses in the F/2 to F/1.2 range that are offering excellent results on Sony FF.

I would agree with Todd in regard to the Nikon Z7. The biggest issues being thrown out are the lack of two card slots something that would not have even been noticed there or four years ago. Others issues include the 1/200th sec. top flash sync and the AF-C. Image quality is in a word superb and on the same level as the D850. I had no issues with AF-S during you short one day use of the system. 

 

Regarding growing pains like Sony, Olympus and Panasonic when they went to mirrorless a full set of native lenses will take a while to roll out. That is what makes the MWL-1 and SCM-1 & 2 lenses so ideal for this system. With the FTZ DSLR lens adapter and the current Nikon 60mm F/2.8G macro this one kit can cover a very wide range of view all on the same dive.

 

Looking forward to seeing offerings for the New Canon EOS R system at next weeks DEMA show.

I had an opportunity to use the MWL-1 with the new Nauticam NA-Z7 housing and Nikon Z7 camera two weeks ago. The system was outfitted with the Nikon 60mm macro for DSLR's and the Nauticam SMC-2. The lens ships with a neoprene dome cover and my test unit had the Nauticam dual flip adapter. My test unit did not have a buoyancy collar and I used float arms which seemed to offset any imbalance. The Nikon Z7 has the same growing pains found with the first generations of the Sony A7 cameras and other mirrorless offerings. Build quality of this camera is superb the best of any mirrorless I have used so far, excellent weather resistance. I only had the system in the water for about two hours so hardly enough time for a full review. I did like the idea of being able to cover from 150 degrees AOV down to 4X in macro. Attached are MWL-1, 60 macro and 60 macro with SMC-2 photos.
