Hello, everybody! I am recently eating sushi sold at the convenience stores more often. These are not as good as what you will find in restaurants, even the ones from a sushi-go-around tastes much better. Their price and convenience are the main factors why I kept eating them, specially for breakfast. It hits the spot, even just barely and that’s good enough. It always leaves me craving for better quality sushi but when I’m hungry and lazy anything will do I suppose. Today, I’m going to show you something that satisfied a need back-in-day. Just like cheap sushi this was better than nothing at all specially at a time when people were demanding for a cheap-but-acceptable solution for a wide-lens that’s capable of being mounted to early SLR’s. Read the whole article to find out more about this.
Introduction:
The Carl Zeiss Jena Tessar 40mm f/4.5 we see here is the later version of the Carl Zeiss Jena Tessar 40mm f/4.5 with the smaller barrel. It’s not clear when this was made and for how long but I suspect that it was made from around 1951 and it stayed for a few years until the Carl Zeiss Jena Flektogon 35mm f/2.8 was introduced. It’s merely a stop-gap and this was soon phased-out when the more practical Carl Zeiss Jena Flektogon 35mm f/2.8 was unveiled. Needless to say, this is kind of rare but not valuable at all because the demand for it is low owing to its odd choice of focal length.

It has an all-metal barrel that resembles its peers from the same era but unlike them this does not have a preset-ring so you will have to precisely stop the iris down yourself. This is a bit of an annoyance because you’ll have to tale your eyes off the viewfinder just to confirm that you’ve go the right aperture value set before you make an exposure.
