I took these photos yesterday at my grandson’s high school baseball game. I had my D7100 set up just like Nasim Manusurov recommended. Specifically Shutter Priority and auto-iso. The day was a clear blue sky at about 5p.m. EDT. For whatever reason, the ISO (though I didn’t include all the photos taken) is all over the place. Even the some of the RAW photos show under-exposure. I shoot RAW+JPEG and ususally convert the RAW to JPEG using Photoshop.

So, my question to you guys and gals is: “Am I doing something wrong, or is the camera in need of an adjustment/repair?” I hope that the metadata lends some information to help you help me.

Your thoughts and consideration are appreciated.

My Dad moved to PA as a teenager. Enlisted in Army upon graduation. Asked to be a photographer. His nick name in high school was Click, after all. He got his wish. Was there for Normandy, but not first wave. Was in battle of the bulge, left for Asia afterwards, photographed some on some islands, photo’d MacArthur, Ike, Hirohito, etc. He was also there for liberation at one of third reichs’ concentration camps. Ghastly pictures he brought home. One of the pictures he took is exactly the same as one in Time-Lifes big book. It showed a blackened arm and head of a burned prisoner who got that much out under a wall that had far less space than a head would need in order to get through. How that man must have suffered to go through that and then to painfully die anyway...I hear there are are those that don’t believe in the holocaust. Oughta try talking to some who saw it, up close and personal(ly). He spoke of being shot at while taking pictures and having concussive explosions from artillery nearby. Many think he had an easy time as a photog. They forget he was shooting a camera while people shot bullets in his direction. He had a .45, but was too busy with his Speed Graphic or movie camera to ever shoot the gun. There were only a few hundred war photographers during the whole war. They did all the same stuff the famous privately employed photographers did. They got less notoriety.
He married my Mom while being trained in DC. She was an emplyee of the British Admiralty. Never would tell us exactly what she did, even all those years later. She has Altzheimers now and probably no longer remembers. He died of Parkinsons’ Disease a few years ago. I always wondered about all those wartime mortar rounds and their effect... My Dad went AWOL to marry my Mom right before shipping out. Commander let it go; said it would probably never catch up to him. We haven’t heard anything yet. I think he got away with it. He was a great guy, so was my Mom. I was lucky to have them. Zillions of stories, never to be forgotten. I miss him and her.
That’s the short of it. He later was a great salesman, sold everything. After the war, electrolux and fuller brush. Succeeded there as everywhere. They sacrificed for me to go to college, grad school and law school. On and on. Those who were bored or stopped reading; I understand. We all have our stories. Btw, his parents emigrated from Sicily. No English. No money. Ellis Island, the whole bit. The parents were 14/15 when they got here, betrothed. The American story. His brother became a Doctor, served in Army, as well. I WILL stop now. Remember Scruples, you asked...

Before you tell me not to listen to this Tony guy let me explain. He has the controversy topic of crop sensor which caused a lot of disagreement but I don't want to talk about that. His latest claim that ISO is fake and I email him asking him to do a test of his cameras and see if they conform to the ISO standard and heard nothing back from him.
I don't see how ISO is fake because.
1. The ISO organization is real and based in Switzerland.
2. There is the ISO standard for digital still cameras and the latest is ISO 12232:2019 published Feb 2019.
3. Unless you test the cameras against this standard and they don't meet the standard then you can't claim that they are fake.

I am having to upgrade but can't afford the top of the line equipment like D4s, D5 or D850. I shoot weddings, outdoor portraits, landscape and wildlife, sporting events, street and residential home sales and family vacation. I do shoot alot in low light and have a few flashguns and reflectors. I was thinking of going to the D810 or D750 used or refurbed and also toy'ed with the idea of the D500. I can only afford one and all the reviews on the web sites that sell I don't value much the reviews as most seem fake or embellished. I have been shooting digital for 11 years. Prior to that I shot 35mm film. Love the D90 but want to take it to the next level. Also what is the max print size for any of the above camera formats (FX or DX)?

Within a year of buying my first ever camera (1980 - Nikon FM) I was a full-on photo fanatic. Friends saw this and asked me then, had I not bought the Nikon, what camera brand/model would I have rather bought.
We have a number of other "old-timers" here and I was wondering if any have pondered this question themselves. Back then, what 35mm format camera would you have bought if money was not an issue?

I chose my nikon FM over a Leica because of the viewfinder and not a rangefinder mostly
For me, at the time, I had a huge "crush" on three other cameras, curiously all with German ancestry. My choices were: Rollieflex SL35 E, Contax 167MT, and Leica R3 Safari.

Luckily for me, I didn't know anything about any of them at the time I bought the FM. All of those companies went out of the camera making business some time back. Thank-you, Nikon, for hanging in there.
