In bellow sample code, I am assuming email__c field is available on both object and I am using this email as a criteria to update object1’s field with object2’s field.
There are multiple ways to address your scenario.
1. If there exists a parent child relationship between your custom objects custom1__c and custom2__c, such that custom2__c is the Parent for custom1__c then field1__c can be a custom formula field. Create a cross object formula field on custom1__c that refers the field2__c using the __r relationship. The formula for field1__c as the formula field is as follows. 2. The other way is to write a process builder or a workflow and use their Field Update action to update the value within field1__c on custom1__c based on a value change within field2 on custom2__c. This will work only when custom2__c is the Parent for custom1__c within a Lookup or a Master Detail relationship.
If both the objects are not related then you will require a after insert and after update Apex trigger to update the value of field1__c on custom1__c when field2__c on custom2__c changes.
