Material: pure from the feeling you notice no difference. They seem to have the same thickness and quality. The originals of Olympus is but then a bit more flexible, easy to squeeze so. by JJC is there rather rigid.
Fit: The Olympus GeLi sits on light and fluffy rotate. Still, she sits very firmly. The alternative of JJC is a bit more complicated. Although the bayonet looks the same, but apparently there is something different. It sometimes takes several attempts to put them on straight and they also turn straight. This often tilts and one fumbles a bit longer around it. This can be annoying and causes that you no longer decreases. The filter element is therefore difficult noticeably. Whether the bayonet was now not processed accurately or GeLi a bit is just too big, can not be determined by me.
This will cost a star!
Price / Performance: The price to the original is almost one third. So will only cost you 33% of the LH-61D. For JJC requires an outrageous shipping! With 8, - costs LH J61D then already 18, -. So almost 70% of the original. Amazon shipped the LH-61D free because so incurred no additional costs. It may sound stupid, you have to keep in mind. So the two separate scarce then 10, -. If you order several parts at JJC goes sometime certainly fine, just do the least!
The lack of fit and for quite a high price compared with the original makes the GeLi not at a bargain. Personally, I grab the next time back to the original, and then stay there too. Each of the EH is a large order with JJC going, which can order the LH-J61D quiet. For 10, - it is quite in order.
