I would repeat what others have already said, perhaps from the reversed angle.
I am a totally newbie with the Electro cameras. Last Friday I went to some place to use it for street photography, that as you know demands quick manipulation.
At home and even at some quiet situations the Electro have seem to me an extremely easy camera to handle. Great yellow patch, no exposure worry, very grippable, etc. Yet as a newbie in the street, that Friday I was in great pains with quick focusing, with finding the focusing ring instead to the f/stop ring and vice-versa, with depressing the trigger at the right point, and with quickly winding.
Of course all these are not but newbie troubles, that I will eventually overcome with due time.
I, for all my varied gear, envy your control of your Electro. Reverse this sentence, and it means you do have an extra asset with that camera.
In other words, "Mother, there is only one".
I take no sides concerning wether you may buy other gear, as there is no reason why either you or me will eventually become versatile in their manipulation. It depends on your feelings, budget, and your sense of wether you are done with your Electro and need more features, which the Electro is denying you.
But I bet that for those instances in which you would like to feel a hundred percent sure of the results, you will comming back home. There is nothing like home.
So take it easy, go along your budget and nose, and for sure relief yourself you are working with an "outdated" camera.
Best wishes in your Odissey,
Ruben
