I was not happy with Luminar 3 due to speed (exporting pics is a reason for a bathroom break or getting some coffee. But I reluctantly went to Luminar 4 and I am glad I did. Speed had greatly improved and they have made some other adjustments as well. I am assuming they will continue to improve their product.

Thanks for your input, good to know.

No, Sigma does not make a Tripod Ring for this lens. The body weight of the lens is 2.5 lbs and worked well on a camera tripod when I tried it. I understand there are some third party companies that make them but I never needed it.

Purchased a Canon 100-400 from Kalina54 recently and it was as advertised. Absolutely mint condition.

Do you have the protective bag for it?

No Lens Cover?

I agree that the sharpness and detail are excellent but the colors are simply amazing. I have seen some other pics with the Canon 90D. The 34 mp creates great detail but they did not rave as much about the colors. The first two of the snakes are just outstanding.

Thanks to all for your responses, I learned quite a bit reading them.

No it was uncalled for. You took it from a question that maybe needed more information to a sarcastic mocking response.

First rule of every public forum site I have been on, is it you cannot say something nice, don't say anything at all. CycleSpeed pointed out in the post before that that more information was needed and I replied.

You tried to mock the question, implying the use of over 19 year old computer using 5.25 floppy dissc. That was not needed.

In reviews of the Luminar program various reviewers have noted it was sluggish. I have it on two computers and it is sluggish compared to PS Elements and LR.
In November Luminar 3 has had a problem with the program giving owners a reading that it could not import pictures due to lack of disk space on a persons computer. I had over 500 Gigs in my computer and the program would not import photos. While I received good technical support, it took a while to get it corrected.

Getting it corrected involved the following
Download AppCleaner from here (click this text to open link).
Install AppCleaner and start it.
Drag Luminar from your Applications folder into the AppCleaner window. When removing Luminar, mark all the files and folders in the list, except for DPA6233TPQ.com.macphun.luminar3.
Once you've uninstalled Luminar, restart your Mac and download a fresh version of Luminar from here (click this text to open link).

Maybe my question did not fit your guidelines of what a good question should be, but you decided to react with sarcasm that was not needed.

If you cannot say something nice, keep you hands off the computer keys and don't type anything at all. Wait it out.

This comment was uncalled for.

I have 8 gigs of ram on a Mac Mini that is a 2017 version. I notice it seems to take a long time to have the picture come up that you want to edit.

So Luminar 4 is have some specials for Black Friday - Is the new version faster than the old one? Luminar 3 has had some problems with running out of disk space as you download files. Does that seem to have been fixed.

Like the program, just seems to be really slow to work with.

For sale is a used Canon 7D. It comes with 17,623 on the shutter. Will come with 2 generic batteries, strap, charger, USB cable and and manual. Generic grip. Price is $410 that includes paypal and shipping to Lower 48 states.
