1. He does indeed confuse blur and bokeh.

 

2. What you are saying about exposure time I do not understand. For a given amount of time, at the same iso and same aperture, exposure time is always the same, regardless of camera used.

 

3. If you are talking about noise, you may be right about the specific iso value, provided the sensor tech of the cameras compared is similar.

 

4. Smaller sensor tech, smaller within reason, is much more rapidly advancing than the larger sensor tech, and it appears to be resulting in noise leves which are less than before. F.e., the latest Olympus 20 MP sensors are a stop better noise wise than the older 16 MP sensors, despite having 25 % more pixels.

 

5. Apart from that, IMO it is horses for courses. Don't shoot over 3200 iso with the previous incarnations, and not over 6400 iso with the newer ones, and you don't see the noise at 45 cm x 60 cm prints unless you use a magnifier, or larger even when processed properly.

 

Kind regards, Wim

I added numbers to answer point for point.

 

1. Agreed.

 

2. Of course it is so that for the same ISO setting, the same f-value, the same exposure time is needed for a similar image exposure result. Are we actually talking about that? No. Because, with the same f-value we would get a different DOF. And this is not it, this is same settings to get a different result.

 

We want the same DOF (DOF is one of the 2 things a photographer can change to change the look of the image, the other being FOV). So what are we talking about? Equivalent settings to get a similar result. Equivalent focal length to get a similar FOV. Equivalent aperture to get a similar DOF. And, equivalent ISO setting to get similar exposure time. Nothing more, nothing less. So: NOT the same focal lengths, NOT the same f-value, NOT the same ISO setting. Simple.

 

3. No, I have not talked about noise. A Canon EOS 5D has more noise at for instance ISO 400 than a Canon 5D mark IV. An Olympus E300 has more noise than for instance an Olympus EM-10 mark II. Equivalence never is about noise, it is about 2 lens things (FOV and DOF), and, if one wishes a similar exposure time for whatever reason, also about equivalent ISO settings. For the exposure time. Now, if some equivalence denier will be silly about noise, indeed,one  can point out that that for similar sensor tech, the noise will be similar. And one can also point out that, indeed, for the same sensor size, noise is not similar across sensor generations. 

 

4. That does not appear to be true (the faster advancing part). It is more like MFT is finally catching up to FF Sony sensors, noise wise, when you look at equivalent ISO settings.

 

5. Can't argue with your personal preferences. So, agreed.
