Basically, the panel fulfilled its purpose. Good workmanship "for a piece of plastic". Installation is clean and fast in both directions, both for use as well as for transportation. Deduction he gives for the description and the lack of evidence that this model is not suitable for the ES-F 55-250mm IS STM (!!). The closure does not fit. The 'error' but is closer to Canon, why is the lock changed at all ?! Amazon would in my opinion have to turn a little hint. Therefore, some deduction in the evaluation.
