Worth Noting

Positive elements

probably one of the most interesting M lenses I've got across my desk in quite some time. This is from a company called Omnar. It's called the Bertelli. Now, it's based off the 1934 Ludwick Bertelli Jenna lens. And this is one of those lenses that's going to have a lot of character. It's a 5 cm F2 or 50mm F2 lens. And look at this thing. This is beautiful. Look at that. That is stunning. Comes in three versions. Silver, black, and then black with a little bit of brass coming through them. All of them are brass, by the way. And they are very limited. I don't even know if they sell them anymore or not because and they're quite pricey on the website. But when you feel this lens, trust me, this is quality at its utmost level. Now, look at this thing, which is cool. When you go to um close focusing, by the way, you can go to 7 m on this. You can see the barrel of the lens there. And then when you close it down, that closes off there. Now, the aperture ring is on the front here. And it is um there's some tension there, but it's not the easiest thing to adjust on the fly. So, you probably want to preset your aperture before you take photos with this. Now, I've taken some photos around the house. Nothing to show you right now, but just off my first observations, f2 is going to be a little bit soft. F2.8 and beyond that, it sharpens up, but you get that sonar pop, that kind of 3D pop that you might have seen out of older Zeiss lenses. That's kind of the vibe of this. And with the build quality and that look, this is going to be very, very exciting to test out and do a review on it for you guys. So, big thanks to the team at Omar for sending this out my way. And yeah, the Brtelli coming up very soon. But look how beautiful this is. Damn, that's nice.
