I found this one at a cheaper price. But it is 7x instead of 3.5x.
What difference will this make?
Micrscope is the same thing, just with or without the 0.5 barlow lens included.
Some sellers ship the x0.5 with the microscope and advertise it as 3.5x
Mine came with the x0.5 and the 2x lens.
Adding the x0.5 makes a huge difference to the working distance, it's ~16cm. Plenty of room to get the iron in.
From memory its like half that without any barlow lens.
It really is a win/win for electronics use. You get to zoom out more and fit more PCB in the field of view and get awesome working distance. You lose the ability to zoom in as far, but the microscope head has more zoom than needed anyway, so it doesnt matter.
Side note: The 2x barlow makes the working distance like 1 inch. LOL
