http://www.PRECISIONCOLORS.COM Outstanding !! GREAT OEM color match to Epson..I have an Epson R2400 printer that uses the SAME inks as an epson 3800.( He DOES have the inks for your 3880) . Mike's color matching is beyond reproach, and I feel the BEST for aftermarket pigment inks. PERIOD!

I've been using a Peak design Slide for 2 years with my Nikon D500 w/Grip mounted to my Tamron 150-600mm G2. The absolute BEST solution I've found for my combination! I have a ARCA type plate with a slot attached to the built-in ARCA mount on the lens, and I attach one end of the strap to that slot, and the other end of the strap to The left-hand eyelet on the camera body. That ARCA plate I added is also fits on to an ARCA tripod mount in just seconds if I'm not shooting hand-held!! The strap , when I'm shooting w/o a tripod is worn cross-chest carry style, and the Camera and lens is moved quickly to my right side, or all the way to my back-side with NO Bouncing around whatsoever!!

How about a 1.3mpxl Kodak in the late 90's that sold for over $800 USD!!..BUT..I was earlier scanning film and slides with a Microtek 4000 DPI scanner that had a "scuzzy" interface, which I don't believe any computer can use today! I was then printing out these scanned files via an early Epson 1200 dye based printer! (If someone can tell me how to add a scuzzy interface to a windows 10 pc with an intel 7 series processor I would certainly love to hear from them, as I would like to power up this scanner!( or sell it to someone who has an exiting Scsi interface! This was lightly used and originally cost me over $1400!!

I've had my Tamron 150-600mm G2 mounted on my Nikon D500 since November of 2016 95% of the time, and no focusing issues whatsoever (other than shooting in "available darkness")!! No complaints here!!

I have tried Gigapixel AI in the past(twice!), and was not completely satisfied with the resuts I had..More recently I've been using the "free" APP from Adobe photoshop Cc called "ENHANCE", and it does a creditable job of doubleing the size of a photo (or cropped photo) in RAW, .tif or .jpg without any artifacts! IE, if you have a sharp photo to begin with, you can enlarge a 12.5"x18.5" image to become a fine one at 25"x37" at 300 DPI!! This app also works quite well on smartphone images as well. It bears repeating that you do need a very good imafge to begin with wheter it's from a camera or a cellphone.. Depending on th photo, I may also apply a light bathing in Topaz Denoise AI once finished!!

I've had my BEST experience from "STK" batteries sold on Amazon for my Nikon D500 (en-el15) I use 2..one in the body, and one in the grip.. They lasted longer than any of the other 3rd party ones, and even including "original Nikon" versions . They are assembled in China with cells from Japan. Less than $20ea USD from Amazon..

I've been using Topaz Denoise AI since it first became available, and it was GREAT then, and with MANY imrovements since that time, it is nothing short of "STELLAR!!!" I shoot on ISO AUTO with a ceiling of ISO 4000 on my Nikon D500, and I have no fear of uncontrollable noise at 4000, and have made prints at 16x24" without any visible noise once processed in Denoise AI.. I think it's the BEST app for noise reduction that anyone has come up with to date!! It also works GREAT at "higher" ISO's with prints of 8x10" to 11x14" with barely visible noise at ISO 6400!!

Unless I missed it, I've heard no one mention Photoshop's "ENHANCE"..It's a fairly new app included in Photshop CC that will through "AI(AKA machine learining) which
will DOUBLE the sized of an image with NO artifacts.. I've tried it out on several images, and I think it beats "Gigapixel" from Topaz. I took a 8mpxl image from my Samsung Smartphone from it's normal max for a decent print at 10.5" x18" up to 21"x36" With NOapparent image loss whatso ever.. If you have Photoshop CC try it out! Of course, you need ad good sharp image to begn with. I found the results AMAZING!!

I've had rhe Tamron 70-300 VC DI in Nikon mount for about 8 years..Reviews at that time were quite vavorable and most thought is was on par with the Nikon version but less cost of course! I have not used it much in the last 6 years since I purchased My nikon D500 along with a Tamron 150-600mmG2. BUT that said, I really did like the results I got from that 70-300 Tamron!!

A PEAK Design Slide stap is Great for my D500 mated to My Tamron 150-600mm G2! No bouncing around either! About 65 usd !!!

Go for PrecisionInks
..professional quality,and a dead match for the epsoninks!!

I totally agree with John.. My D500 Nikon coupled with a Tamron 150-600mm G2, has been in constant use since November of 2016 and as been MANUAL mode, with AUTO ISO set with a max ceiling of 4000 (for the most part!) , and has produced mostly on-target exposures! I adjust my shutter speeds and/or aperture for the prevailing conditions!! (FYI, the ISO can be overridden to HIGHER ISO's for extreme low-light conditions with the touch of a button!) This D500 has been the BEST Camera I've ever owned for wild life or fast sport action!!

STK brand from amazon for my Nikon D500..they seem to have a lifespaN BETTER THAN THE oem nIKON EQUIVALENTS AT $19 USD EA.

IMHO..Buy receivers, they're comparatvely inexpensive.. I have Yongnuo 2.4 GHZ sender and 2 receivers for my Nikon D500. The newer Yongnuo flashes have the receiver built into the flash!! I'm sure Godox will have separate receivers available at a nominal cost!

I've had my Nikon D500 mated to a Tamron 150-600mm G2 since November of 2016..No "ISSUES" with either!! A marriage made in Heaven!! (AND I STILL HAVE ANOTHER 1.5 YEARS WARRANTY ON MY Tamron!!) Most testers have compared the image quality on par with the Nikon 200-500, but it was too "heavy" for me to handle, so I got the Tamron!!
