The 150-600mm f5.0-6.3, setting the record straight

Be fair. The Canon is an f/2.8 prime lens.
 
It's a good point that resolution infinity makes a great lab test but not a great photo. A great photo does not have to set records for resolution.

The majority of internet video reviews are entertainment with little technical depth or detail. They are no better than your neighbor's shallow comments after a few photos. Not worth the time it takes to view them. Eisel makes an effort to offer more extensive professional testing, comparison, and information, especially for photography he shoots professionally for years with multiple systems.
In the case of the OM-1 II review, it would have been nice if he'd put a little more effort into getting his facts straight. His claim that the OM-1 II remains fully functional while clearing the buffer nearly had me ordering one, and I know some other people were excited about that too. It was disappointing to learn from an OM ambassador that in reality this hadn't improved from the OM-1.

Obviously in a long review video it's reasonable to expect a few mistakes, What damaged his credibility with me is that he doubled down on the incorrect information when it was questioned in the comments. It would have taken moments to check it for himself and correct the mistake.

Maybe that was just an isolated error and everything else he's put out have been 100% accurate, but the impression I got from his gushing over OM's "masterpiece" is that he's more a salesman than an objective reviewer.
 
Not only that, but he didn't watch your video!

You should be offended after making so much effort to provide the details.

He is a known OM-System fan. And also a Nikon DSLR fan. Nobody else provides more information.
 
But I did see one interesting thing in this video. He claimed to conduct an MTF50 test on the lens, and showed charts and stated that the resolving power of the lens at 600mm was HALF that of shooting at shorter focal lengths.
I wouldn't put too much thought into any MTF measurements he provides. He did another test where he showed results that were higher than the theoretical maximum which strongly suggests he doesn't know how to conduct the test properly.
 
Look at the photos, not the tests of the photos.
 
Here is an interesting review from someone trustful being not an ambassador and having bought the lens for himself.

That's a good review worthy of the title of this thread, thanks for posting it
It's an interesting thing:

While Eisl knows his photography, he uses buzz words and doesn't necessarily explain much - just parroting the blurb. "Voice coils"??? I know what they are - a precise actuator used in speakers. Many devices need and use precise actuators. IBIS / OIS included. It is a given that they have a high level of precision otherwise the stabilisation would be crap. Throwing in a feel good buzz word just sets off my bullsh*t meter and I am likely to develop a negative attitude.

The small sensor review, on the other hand, tells it as it is. I think I had already read one of his earlier reviews but after reading that one I have a much better appreciation of the 150-600 and wouldn't hesitate to buy it if circumstances dictated / allowed.

I have no negativity towards that lens now, while after watching the Eisl video I was of the opinion I would probably NEVER buy it.

I wonder if marketing depts, factor in reactions of those that aren't swayed by hype or are indeed put off by hype. I wonder if marketing types actually have the capacity to understand such concepts...
 
He seems to stick with evidence. His reviews and expert guides are highly detailed and technical and he avoids talking about himself and trying to be entertaining. Much better than many reviewers who offer shallow opinions that anybody can provide by just picking up the kit and taking a few photos. His videos are worth the time it takes to watch them.
That's just too funny.

He is a droid, programmed by the marketing department, kitted out with voice coils that insert buzz words at the push of a button.
 
Not only that, but he didn't watch your video!

I consider accuracy of information more important than quantity. For me it loses a lot of value when some of the content is downright misleading, especially if errors aren't corrected when they're pointed out.
 
Make a better video and post it.

Well, no. f8 on FF is not equal exposure to f6.3 on M43.

I get that you're his no.1 fan and are doing your very best to defend his honour, but that isn't really an argument.

I'm not a professional Youtuber with an OM-1 II review that claims to "dissect every single one of its features". It's his job, as someone who presents himself as an expert, to test the camera properly and get his facts straight.

That issue of functionality while clearing the buffer was brought up in the comments section of his video. Really, that should have been enough for Eisl to double check and correct the error himself, but instead he responded with more incorrect information.

Am I really being unfair and unreasonable if I find him a less credible source after that?

F8 is F8 on any lens, as far as the exposure triangle goes.
That is excellent news the Nikon p1000 goes to a 3000mm equiv focal length at F/8 would you be expecting the same result ? I wouldn't I would expect the OM-1 image to be far far better

These 4 cameras are taken at the same aperture same lighting same subject same settings tell me do the results look the same to you. It is the end result that matters .DPreview low light RAW 12600 samples 1" , OM-1, Z6 II all shown at 100% and finally the MF GFX 100 which was too big to show at 100%

It is the result that matters

The explanation of equivalence is ridiculously simple and there are no legitimate reasons for not understanding it beyond not being smart enough to get a topic that has been explained literally 1000's of times. Or alternatively understanding it but prepared to outright lie in a deliberate attempt to spread misinformation.

Sadly I doubt that there are many stupid people in the forum. Which means that a good number { though thankfully a minority } are deliberately setting out to deny a fact and spread misinformation which I simply cannot understand. Like everyone else I make mistakes but I would much rather have the facts explained to me than make a fool of myself and argue that black is white. Which some folk here have been doing for years

It is perfectly reasonable to declare that you don't care about equivalence if you only use one format . But that does not change the fact that it true and applies equally to every format.

Eight years ago when that sly old Guy Parsons tempted me, and I bought my first PL1 Olympus, I didn’t know what an F stop or ISO or the exposure triangle was.

I learned from a book, PL1 for Dummies, and with the help of my friends here.

Until tonight I believed that if I used aperture priority f 8 on either my Olympus 75-300 lens on my M5 II or my Canon 70-300 lens on my Canon 7DII the iso and shutter speed for an f8 lens opening according to the exposure triangle would be the same.

Since my Oly M5 II has much better stabilization I can raise shutter speed by increasing ISO, to freeze the bird.

But does the exposure triangle (not depth of field) for a f8 vary according to sensor size, or focal length of the lens?
