You could say the same about lenses ...

I would not say the same thing about lenses. A modern digital camera has far more individual features and functions and parameters and variations thereof than a lens. Much more detailed analysis and reporting are expected. All you have to do to confirm this is look at professional camera reviews compared to professional lens reviews.

I just noticed this part. All of those characteristics - and of course many others - can be found in the camera manuals and other documentation available online from Sony. Reviews are not needed for that kind of data, though a review can include such data.

I now realise that several of these things can be easily predicted by the camera model number alone, but that wasn't obvious until I made a simple table which shows all of this (and a bit more) and which is dead easy to read and compare.

Dyxum used to have a similar feature where many such things were pulled from the existing camera database and conveniently displayed in a table format. I don't know what happened to that.

I am leaning towards lenses being just as complex as bodies. Certainly prices are somewhat indicative. My A5000 is very simple, just a sensor, a CPU and some buttons, but a zoom like the 18-110G OSS has all kinds of stuff going on. Some lenses have electronic user interfaces now (Zeiss Batis lenses with OLED displays).

Yes, you can find out this sort of data about an individual camera by downloading an individual manual, but if you're looking at a camera on ebay or in a shop and wondering if it will do what you want, that's terribly cumbersome.

For example, here's my table:


I've highlighted some areas to illustrate differences I felt were important, but even if you ignore those you can see at a glance which cameras (for example) have an OVF and take SD cards.
Miranda F & Sensorex, Sony A7Rii, A58, Nex-6, Dynax 4, 5, 60, 500si/600si/700si/800si, various Sony & Minolta lenses, several Tamrons, lots of MF primes and *far* too many old film cameras ...

The point is how much one needs to 'review' about a lens compared to a camera. There isn't all that much to reveal. Have you noticed that camera manuals are dozens or hundreds of pages long while lens user manuals (the ones I know about) are contained on one folding page?

Sorry for the belated reply but I thought I had already responded (clearly not)

Do an online search for something like 'Sigma teleconverter compatibility chart' and although I cannot verify if one or all are accurate from the various Sigma sites worldwide, they should give you sufficient info, though the next obvious suggestion would be to contact your regional Sigma agent via their website and ask if they have an updated 2017 compatibility chart available assuming the posted chart is out of date and/or to ask them to send you a list of lenses that the matched Sigma 1.4x and 2x teleconverters will work with.

You can see my Google search results here and the Sigma (USA) TC/lens chart can be viewed here.

Hope that helps somewhat.

No problem. I didn't imagine it was compatible with any lenses I currently own. I did have the Sigma 70-200mm F2.8 EX DG APO briefly which I believe is compatible, but that particular copy of that lens didn't seem sharp enough on APS-C to bother with a teleconverter.

With respect, you can't. Not on my computer monitor, at least, because you cannot get the whole page on one screen without the text being unreadably small, and so much irrelevant and unimportant stuff is there it makes it very difficult to extract the salient basic comparative information.
Don't get me wrong - I like M. Hohnmer's charts and use them a lot - they're on my google page as a frequent destination - but there's value in a much simpler chart for basic stuff.

Anyway, this is getting a bit OT. I do wish there were pages for camera and TC reviews/comments even if it has to be udnerstood that nobody is going to do a complete camera test - it's often the things that aren't in the data, that come out of using the thing, which are important to make a choice.

Thank you very much for your very very useful topic.

I have a fresh info to using Sigma AF 1.6x MD-MA multiconverter - as I yesterday realised, this converter is 'fully' usable with sony A68 in AF mode, converter lives and works and I was yesterday happy from it :) therefore I decided to inform all of you folks

I tried it with these combos>>
minolta md 50/1.7 and sigma > sony a68
tair 135/2.8 (M42) so first M42toMD adapter then sigma AF 1.6x MD-MA MC > sony a68

AF confirmation was correct by manual focusing, autonomous AF works - with small limitation - must be manual focused to approximated distance, for example if object is in 5 meters, manually must be focused between 4-6 meters and from this position AF multiconverter is able to focus itself, yoop!

I hope, it helps to owners, till now I had only Dynax 7D and with this old but nice camera multiconverter doesnt communicated.

My Sigma 1.4 EX TC, previously works well, does not support newer 70-200f2.8 HSM OS. Following my googled result and here, just bought a Kendo MC4 DGX 1.4x and it behaves exactly same.... all newer lenses are not supported except those not having any SSM/HSM built in motor.

Maybe you have a faulty teleconverter or perhaps an issue on your camera? My Kenko α-AF 1.4X TELEPLUS MC4 DGX works fine with my Sigma 50-150mm F2.8 II APO EX DC HSM. It works on pretty much all my lenses. The body does seem to matter though. Even the 18-55 works fine on the DGX on the A68.

For the compatibility of Sigma teleconverters you better check here. Had your TC a serial number above 5000001? As you say you do not have luck with SSM/HSM lenses (and I guess SAM), it looks like your TC is not compatible with in-lens motors. Are you sure your Kenko is DGX? Does it have eight contacts?

(I assume Kendo is a typo, if not, you probably have a cheap knock-off )
