As far as eBay is concerned, even if there is "no return", you are protected by the eBay system. If the lens does not work or is not as described, you can ask for a return.

FWIW and whether relevant or not I don't know, but there will be a return time limit and if the purchase is made outside PayPal eBay aren't always able to help. That's how scams are achieved. As I said earlier, caveat emptor!As far as eBay is concerned, even if there is "no return", you are protected by the eBay system.

Notwithstanding, the OP hasn't told us the source of the lens and only asked if it will work on certain named cameras. Nothing more.
I take therefore that the purchaser is considering your lens, but this is an assumption. It might be another which wasn't converted by an expert such as yourself with the offer a reversal backup. Others have made the conversion and add an 'at your own risk' warning.

If you have a vested interest it wouldn't have hurt to say so as for all I know it might be a no returns sale off flea-bay for a knackered offering when my advice would still be valid. The OP didn't state the seller and there are some dubious practices on the auction sites as I'm sure you're aware (but not everyone is.)

The "conversion" is purely a matter of changing a few lines in lenses data file. So it can be reversed by changing the figures back. As there is no hardware modification, it is very unlikely it has been done to "hide other issues".
Maybe in theory. Changing the code values someone else has attempted may not have been made accurately and as a second user you may not be able to reverse the process. It isn't without possible pitfalls! You sound very trusting.The "conversion" is purely a matter of changing a few lines in lenses data file. So it can be reversed by changing the figures back.

It should work just fine. If purchasing locally take your cameras along and give it a try. If a distant sale from a dealer you'd be covered by the DSRs with the right to return it if it proves to be unsuitable. Make sure the conversion job hasn't caused other issues not mentioned, but I'd guess it ought to be fine if done competently!
If a private sale 'caveat emptor.'

I still feel this type of image needs something reasonably sharp to stop them looking like errors, such as when forgetting to set a suitable shutter speed. I've got similar looking colour slides where I've done just that and no, they are not for publication! Perhaps panning a bird or aircraft in the sky with a slow shutter speed would solve it giving something of an impression of speeding home before the sun sets. In other words use the technique for a purpose rather than as an end in itself.

Amazingly the M50 body is lighter than the MX-1.... by one gram!

Easier than pressing the EV compensation button right next to the shutter release and turning the read dial? It must be fantastic then! But does it do Rich's & Don's 4K video? If not its useless!Oh and just out of interest, my little Canon M5 has a exposure compensation dial right next to the shutter button, it's far easier to get to than the K-3II

If Pentax were to become a video company it sounds as if they'd have the custom of Don and Richard. But probably not anybody else!
I doubt Pentax could compete with Sony for the camera they want. Sony are basically an electronics company and it is simpler for them to not bother with TTL viewfinder systems. If someone wants a TTL viewfinder camera I believe I'm right thinking Sony isn't really on the shopping list to spend one's thousands.
As with cars, one buys the make and model that suits at the time. It might not be the same brand every time, however a firm isn't going to go bust because two people decide to change brands for a feature the previous brand didn't offer. What an arrogant thought.
One has to wonder why they bought into a system that didn't offer the features they wanted. A mistake perhaps, or lack of research?

it's not always about how fast the af works but how fast (and expensive) the WORKFLOW is.
You and Richard seem to have a need for something not provided for in optical TTL cameras and if they exist I'm sure you'd both have one already. I'm sure in time Pentax will improve liveview which may go some way to offer what you want but that isn't the native format for those cameras. All the mirrorless offering Pentax have ever produced are now obsolete. Doesn't that say something? Whether you like it or not it would seem they weren't supported in the way their DSLRs have been otherwise I'm sure they'd have changed direction to build on them which it would seem leaves you both out on a limb as far as Pentax cameras are concerned. Others who are quite happy with them as they are use them too you know. If the R&D to produce the cameras you require made the new offerings much dearer perhaps they'd price themselves out of a market they don't even want to be in given their limited appeal. If you want a mirrorless, just go and buy one, no one's stopping you.JAK wrote:

But for the Op's information. If the lens arrived and didn't work, it can be returned under the eBay system as long as it was paid for on Paypal. The time limit is usually 30 days. But that is better than many. True, operate out of the eBay system and you are on your own. If you want more piece of mind, SRS have a couple in with a one year warranty but at nearly twice the price albeit with the SDM "working".
With that whole series of lenses, it does very much appear that it is not a question of a good or bad one but rather if the SDM has failed or if not, when it is going to fail. Actually, I prefer using both the 16-50 and the 50-135 on screwdrive. As many have said, if anything the AF seems slightly quicker and the noise is not much more. Certainly quieter than the "clunky" F series lenses.
