Just got a real good deal on a camera

[SassyAngel111]

I just picked up a Olympus E420 for about 100.00 with a 14-42mm lens. If anyone has experience with this camera could you please tell me if you had used these: http://www.amazon.com/gp/product/B00AD7YGSM/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=A2LM6ZPY06LT1N and if so how did you like them and will I need anything special to connect them to the lens that I have?

thanks for any and all feedback.
