all the folks have given you good advice, not much I can add except it takes time and patience to get the shot you want. Don't be afraid to push the iso up to get the shutter speed you need, at least 1/2000 sec. We put flowers in the vicinity of the feeder to entice them to come there. Single point focus works best for me.

Thank you all very much for the kind words.

This was my first attempt at using the Olympus OMD EM1 Mark ll in the pro capture mode. The lens is the MZuiko 12-100 F/4 Pro. Shot at 1/12,800 sec at F/4 at 60 fps at iso 4000. These are the keepers from probably 10 different attempts shooting 50 or 60 frames each time. The crossbow we were using fires the arrow at over 300 feet per second.

I have been a Linux user for 20 plus years now and I do all of my post processing using the Linux system. I am a fan of open source software. I shoot raw images and have tried several programs to process them, but the best one I have found is Raw Therapee. After I process and save my raw file to a JPG, I go to a windows program that I run in Linux under Play On Linux (wine) called Smart Photo Editor (https://www.smartphotoeditor.com/?gclid=CjwKCAjwkrrbBRB9EiwAhlN8_FPS59_vComWM_aXmJVz19gwD16OhfKvCV4rTMmDc6CaKnImdu0xORoCuGUQAvD_BwE) and make any other "tweeks" that I want there, and then if I want to clean it up further, I use Gimp. I might also add that I use the Linux Mint operating system

I would love to have a local camera store to buy from, but here in eastern KY the closet local store is either in the next state or half way across the state so I have resorted to trusted folks like B&H Photo for the past several years and have bought several cameras and lenses and other equipment from them and have always been happy with their prices and their service.

Fantastic photo, great work.

I can't speak to this particular lens, but I know Rokinon glass is top notch. I have an 8mm fisheye for my D750 and it is tack sharp, I have 3 other photo friends that bought the 8mm after I did and they all agree it is one of the sharpest lenses they have ever shot. I have used the 8mm on my EM1 Markll with an adapter and it is equally as sharp. I don't think you will be disappointed.

I have an older 4/3 MZuiko 70-300 lens that I use with an adapter on my EM1 Mark ll and it is super sharp.

"Olympus makes great cameras and excellent optics. They started out with scientific and medical optics. The downside to the Olympus. 4/3 format is smaller than the DX and FX formats. Second party lens makers don't support Olympus, which make Olympus lenses pricey since no competition."

That's not exactly accurate, Sigma, Tamron, Leica, Panasonic and others all make 4/3 lenses for Olympus cameras, and you don't have to look far to find stunning images taken with the 4/3 format.

I use GIMP daily as one of my post processing tools along with Raw Therapee. they are both very capable tools.

An older Olympus 70-300 in the 4/3 mount that I use with an adapter to micro 4/3 on my EM1 Mark ll. Really sharp all the way out to 300mm.

Gimp will do what you want, you can resize in pixels or inches, whichever you choose and at whatever resolution you want.

The D750 is an awesome camera, buy a refurbished from a reputable dealer like B&H or Adorama and get out there and shoot some photos.

I shot this with a Lumix FZ1000 using it's in camera stiching mode after the shot.

Fantastic photos, I have the EM1 Mark ll and I can tell you that it does not enjoy high ISO in low light either. I have shot it at 6400 iso with acceptable results but nothing spectacular. Here is a test shot with no processing at 6400 iso.
