Sony a6000 ClearImage Zoom and adapters
Jun 22, 2019 00:34:02 #
Not to quibble, but let us not forget that the "600 mm" zoom on the RX10iv is a "full frame equivalent," so that camera's one inch sensor produces a 2.7 crop factor vis-a-vis a 35 mm or "full frame" sensor, or a "full frame" focal length of about 225 mm.

Does Clear Image Zoom work with adapters? I have ... (show quote)
I did a poorly designed and executed test that involved a Sigma mc-11 adapter and a Canon 400mm lens with and without CIZ and a 1.4x Canon teleconverter and even as bad and impromptu as it is it will give you some idea about what you can expect from using CIZ. I urge you to read what I wrote and not be overly judgemental of the outcome. It was totally impromptu, shooting out of a dark house at a target in bright sunlight that was blowing in a gentle breeze at times. Still, with everything that's wrong with my methodology, you should be able to see the benefit of using CIZ at least in this case. https://www.uglyhedgehog.com/t-512458-1.html

Sorry I opened a Pandora’s Box, gents! Head spinning! I’m returning the borrowed 70-300 and will experiment with CIZ in controlled settings, see what I get. Thanks for all your insights and perspectives.

Right, but I don't see that as being a factor in the validity and practicality of the use of CIZ on an a6000 in extending the reach of a 55-210mm lens which is a main part of the question here, along with whether CIZ works with a metabones adapter and a Canon 70-300mm lens.

There's no problem dbfalconer. It's just any time a question is asked of so many people, there's going to be different answers and some will not be right for you and others will be irrelevent. Perspective is a strange thing and everybody has one and very few work for everyone. If you understand everyone's perspective who offers an answer then you can make sense of their answer. If not, you can't. I urge you to go look at the url I offered above. https://www.uglyhedgehog.com/t-512458-1.html

More like a pet peeve -- the RX10 series are fabulous cameras, but as far as I'm concerned the "600 mm" claim is usually so prominent that it seems a bit misleading, esp since the "equivalency" part is usually buried somewhere in a foot note. So it's not quite like putting a 600 mm glass on an APS-C camera.

Well, MDI Mainer, I don't object to you having a pet peeve about that.
It does shoot like a 600mm lens when screwed all the way out so I'm fine with people saying that. It seems to me like it's just a way of having some frame of reference for the effective focal length.Jun 22, 2019 08:22:01 #

Never stated that CIZ would confuse a bike with a fish - in fact, if you read and understood my entire post including the examples in the links I provided it specifically says that it would never confuse things.
I shoot Nikon - guilty as charged.
Here are some examples that I quickly put together. A while ago, the summer before I purchased the RX10M4 in 2017, I also tried an A6300, which is the basis for my criticism, but I have since deleted my test images. However, the RX10M4 pretty much behaves in similar fashion.
The two images below show a CIZ and one that was shot as raw, cropped and up-sampled to the same resolution and field of view as the CIZ image.
I do think you're partly correct - CIZ is an in-camera feature, and should be independent of the lens. But unless you are using 100% Sony compatible lenses, you can't select the zoom in the viewfinder, you have to dial in the amount of zoom in the menu, making it a pain in the neck to use. I may be wrong, but this has been my experience.
I also agree that people should stick to critiquing things they actually have experience with firsthand, and not parroting what they have read, which, depending on the source, could be a parroting of someone else's poorly informed opinions.

It's not a 600mm lens. It's only 220mm. But putting a 600mm lens on an APS-C camera would give you 900mm in Nikon and Sony, and 960mm in Canon. Using a 400mm would be a more accurate comparison, but you are correct in either case, it's not the same.
The spectacular thing about the Sony is that Zeiss managed to create a formula for a lens that has an amazing zoom range, and still keep the max aperture at 220mm to F4. That lens is quite good. Here is an example of a shot using an RX10M3. No CIZ used.

You can assign the zoom function to one of the camera's buttons (at least on the a6X00 models, don't know about the RX10 series) so as to avoid going into the menu.

CIZ does work for video even if the camera is set for raw stills. I keep mine that way. I leave CIZ enabled but raw for mode. Easy.
Gessman is wrong about me and my views and about my "evidence". Anyone who wants to have a serious discussion of that can PM me. Gene51 shows good evidence here, today. Personalized criticism does not refute anything.
Although Imagemeister's work is wonderfully good, the simple truth is that by using Sony free software you can produce exactly what the JPG would have been, from raw, and any JPG, any Creative Style, all the settings within that style AND with somewhat more pixels.
If you don't want to use PP then that's a personal choice but shooting JPG restricts choices a lot and all you gain is CIZ which IMHO does not do as well as CaptureOne at up-sizing.

I don't have one to test. But from what I recall, I put a Canon 50mm F1.4 prime lens on the A6300 using a Fotodiox adapter, and there was nothing I could do to see the CIZ zoom bar in the viewfinder. I just assumed there was no other way to set up CIZ for this combination than to go into the menu.

No, but is like a 600mm on full frame, 400mm on APSC for FOV.

In all the Sonys I have used the CIZ is assigned to a dedicated button and adjusted with the wheel - never used a RX10 - yet.
