Need Help With Large Lens

Hi everyone. I recently got delivery of a projection lens that is stubby and quite heavy. It has an E-type mount. The lens weighs about 1445g, with a length of about 125mm, and filter diameter of about 80mm. I decided to use my standby A7ii as my dedicated camera for this lens. I am not sure that is a good idea. I can't get my fingers completely around the grip due to the lens' stubbiness, and turning the focus ring on the lens ís extremely awkward because I am using that hand to hold the camera by the lens. Not an ideal combo. I am thinking of getting a vertical battery grip. Would that be helpful do you think? Any other ideas? Thanks.

Interesting looking conversion. What lens is it exactly? One big problem I have with such lenses that are very wide at their base is the lens release button getting very hard to reach.

With the battery grip you may get a little more room for your fingers underneath the lens, not sure if that will improve the handling much. For a previous camera I made a grip extension out of mouldable plastic. A bit clunky but very comfortable to use. I extended the grip both down a bit and forward/sideways, with finger gaps to fit my hand. The trick is to use enough material to get a rigid piece and shape it in such a way that no controls or card doors are obstructed.

Thanks Dick. That is an interesting suggestion. I started using the lens, and because I only take vertical portraits the setup is more manageable. In fact, a vertical grip should be perfect. The issue is, now that I have taken a few images with the lens, I am not sure it is sharp enough for my purposes wide open. It does have a very dreamy look right out of camera, but I need to post-process to bump up the contrast. I am going to try different apertures to see how that effects sharpness and bokeh. I shall be posting my results as soon as I finish my next outing.
