For Web API you can add Custom parameter binding ule in WebApiConfig:

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        //...
        config.ParameterBindingRules.Insert(0, GetCustomParameterBinding);
        //...
    }

    public static HttpParameterBinding GetCustomParameterBinding(HttpParameterDescriptor descriptor)
    {
        if (descriptor.ParameterType == typeof(ObjectId))
        {
            return new ObjectIdParameterBinding(descriptor);
        }
        // any other types, let the default parameter binding handle
        return null;
    }

    public class ObjectIdParameterBinding : HttpParameterBinding
    {
        public ObjectIdParameterBinding(HttpParameterDescriptor desc)
            : base(desc)
        {
        }

        public override Task ExecuteBindingAsync(ModelMetadataProvider metadataProvider, HttpActionContext actionContext, CancellationToken cancellationToken)
        {
            try
            {
                SetValue(actionContext, new ObjectId(actionContext.ControllerContext.RouteData.Values[Descriptor.ParameterName] as string));
                return Task.CompletedTask;
            }
            catch (FormatException)
            {
                throw new BadRequestException("Invalid ObjectId format");
            }
        }
    }
}

And use it Without any additional attributes in controller:

 [Route("{id}")]
 public IHttpActionResult Get(ObjectId id)
