The seven-time world champion's triumph at the Barcelona-Catalunya Grand Prix earlier this month has raised hopes that he could land a record eighth crown but the British racing legend isn't thinking too far ahead.
Hamilton - who trails Kimi Antonelli by 41 points at the top of the standings ahead of the Austrian Grand Prix this weekend - said: "In terms of the championship, I'm not letting that stuff... I've been here before, I know what I have to do.
"There's a long way to go. We're not arriving at this weekend thinking about the championship. We're thinking about this weekend, executing the best we can."
Hamilton's win in Barcelona ended Mercedes' winning streak but he feels that his former team continue to have the car to beat.
The 106-time Grand Prix winner said: "This weekend we do have a new engine. It's a step, it's not the whole gap, but it's a step, it's one foot forwards, which I'm really proud and thankful for.
"Still Mercedes are the team to beat, they've won everything else and they've been just incredible this year. They've got a great car, it's an amazing team - a world championship team.
"We have a real battle on our hands and it's going to take absolutely everyone full hands-on deck for the rest of the year to even come close to competing with them, but I don't think it's impossible."
Hamilton also revealed that he was surprised by the warm reaction of his rivals to his first Ferrari victory.
He said: "I wasn't expecting that, for sure. It was really appreciated because ultimately, I have so much respect for all the drivers that show up every weekend, experience the highs and lows, the criticism, the positives, and they still continue to show up with a brave face and do what they do to the best of their ability.
"We're competitors and we all want to beat each other on track, and none of us are happy with not finishing ahead of the other.
"We have GPDA [Grand Prix Drivers' Association] as a tightknit group of drivers, more close than I would imagine any other generation, at least in the last 20 years. It was really special to see the support from them."
