Are you saying that the D850 is on sale for $2100. That sounds to good.Let us all know where we can buy for that price. I may be able to own one now. Thanks JerryLS

SteveR; Are you saying that the D850 is on sale for $2100. If that is true where is it on sale

Busbum; I have basic the same as you except my 27" iMac is 2016. Have you tried to open the online "IManual"I get an error message saying it does not recognize the file When I download to computer I get same
message. I talk with Canon and the person I talked had no idea of the problem. He tried with their Pro 100 and had same problem. He said he would notify the engineers. That was a couple of months ago. Still no fix. Try it and let us know how it went

I have the same combination and the answers you got does not tell you how. I have a nikon D500 and would truly learn to calibrate the lense for the best sharpness. I have not been able to find that info. Thank you all

Sorry I meant to say IMAC 27" computer

I have a canon PRO 100 printer,I use Apple's 27" and 15" MacBook pro computers . Since upgrading both too
"Cataliana Ihave been unable to open the user manual I had downloaded sometime ago, after going to canon"s support and down loaded the software for the user manual I stil cannot open the town to install on the computer. I have contacted both Apple and Canon and they were no help they both told me to contact the other. Has anyone have this problem and were you able to open the manual software? Please help if you have solved this problem.Thank you looking forward to your response.

My thoughts are why buy an entry level camera, Idid and all it did was cost me more money than I had purchased a higher grade camera. Generaly speaking you will problems will upgrade and if you sell or trade in your entry level camera you will lose money.

Sorry about key stroke miss should have been 10.13.6

I am glad you have no problems with the Tap-in.I went to the Tamron Tap-in page and it shows it is compatible with Mac OS 10.10-10,11. I also have io.13.6 update.Thank you for your response.

I just purchase the TapIN a few days ago, but found out that if you have the latest update to High Sierra ( Mac OS ) it does not work, appears to download okay, but will not not open. Talk with Tamron they aren"t going to upgrade the firmware.

Thank you Fotobyferg I didn't have a clue thanks again. I will do some research.

Pardon me, but what is meant by tap in?

Make sure the card you are using is the selected primary slot.You do not have to leave second slot empty.
