> be careful with the super cheap plastic finders Honestly, I've used the Olympus VF-1 Optical Viewfinder for years and its actually super bright plus it never once fell off during my long Chicago walks.

Been thinking about this... ^ This. Also, unfortunately, the original Leica SBLOO 35mm Viewfinder is way out of your price range now. Its frustrating how overpriced theyve become. I had issues with cheap Soviet finders too; theyre not as good as expected and usually hazy.

• Voigtlander 35mm Metal Brightline Finder: Very clear, tho it might push your $150 budget.
• Canon 35mm Metal Viewfinder: Solid vintage alternative that fits securely. Stick with metal, dont waste money on plastic junk.

Re: "Exactly what I was thinking" - honestly i have to respectfully disagree with the idea that you need to hunt down a super expensive vintage metal finder to get a good experience! i know the purists love the old school stuff but if you want amazing clarity without spending your whole rent check, you should definitely check out the TTArtisan 35mm Optical Viewfinder. its actually kind of insane how good the glass is for like fifty bucks. its super bright and has really clear frame lines which is exactly what you need for those Chicago skyscrapers! another fantastic option if you want that high-end feel but cant afford the SBLOO is the Kobalux 35mm Brightline Finder. they were made by Avenon and the build quality is top tier... seriously, the distortion levels are practically zero. its a bit of a sleeper hit so you can sometimes find them right around your $150 limit on auction sites if you look hard enough. dont feel like you have to struggle with tiny windows or hazy vintage glass just because you're shooting a Leica. modern optics on an old body is a total game changer!!

Exactly what I was thinking

Like someone mentioned, you definitely dont need to spend your rent money on a piece of vintage Leica glass just to see what youre shooting. I am honestly super happy with the modern third-party options. If you want something that feels solid and wont slide out while youre walking around taking pictures of buildings, check out the Kipon 35mm Optical Viewfinder. It is all metal and the glass is really clear for the price. I have been using these old cameras for a long time and there are a few things I have learned:

• The metal finders usually stay put better than the plastic ones.
• If the shoe feels a bit loose on your iiif, just put a tiny sliver of tape on the bottom of the finder foot. It is a classic DIY fix that works every time.
• Dont stress the brand name too much, honestly your film wont know the difference. I have had no complaints with mine. It really makes using a Barnack way less frustrating. Just slide it in and you are good to go... no more guessing where the frame ends.

I totally agree that the tiny window on those old iiif bodies is a total nightmare for 35mm. I would definitely suggest being careful with the super cheap plastic finders tho. They feel really flimsy and might slide right out of the shoe when you are walking. Just make sure you get one with a decent tension spring so it actually stays put.
