Where can I find this part for my Vivitar Series 1 500mm f8? I recently bought a Vivitar Series 1 500mm f8 and the barrel part that has the t mount end (shown in picture) broke, and I need to replace it. Is there anywhere that I can buy just the part, or am I better off just finding a replacement for the entire lens somewhere online? Also, if I can just use something else that isn’t that piece but will st…

Is the Sigma 150-500mm** F/5.0-6.3 APO DG OS HS worth it today? For some background, I mainly shoot in the realm of aviation photography and currently use a Nikon D500. I’ve always wanted a telephoto lens that can give me some extra reach over my 70-300mm. With that in mind, I can find these lenses at around $400 which doesn’t break the bank for me and was wondering if this would be a worthwhile upgrade for …

500mm Reflex lens for “plane” photography? (recording rocket launches from a hundred miles away) Has anyone used a long telephoto reflex/mirror lens for shooting things like rocket launches? My 85mm at 1.5x cropped to about 130mm isn’t giving me quite enough reach. I had thought about buying a traditional telephoto, but a 500mm FF lens would be too unwieldy to aim up in the sky for 10 minutes, and would also be pretty expensive. Enter the…

Any 500mm f7.2 sigma apo lens users? I it’s ancient but I’m about to buy it for less than the cost of 1 month bus pass with a secondhand warranty. What advice would you give to get decent photos out of this? I’d like to use handheld but guessing a monopod or tripod would be advisable? Mostly birding. Will be paired with a d300 but that’s getting an upgrade of some sort later in the…

70-200mm or 100-500mm for landscape? I’m a hobbyist. I have a Canon r6 m2 with 24-105mm. I’m happy with the combo, but I want more reach. I mainly shoot landscapes and maybe animals if I can find them in the parks near where I live or during a trip. There’s a Canon sale right now, both lenses with $200 off. I want to buy one of these lenses. 70-200mm is more versatile but I’m afrai…

Cheap 150-500mm Zoom or Good 70-200 with a Teleconverter? I am looking to extend the reach of my current lenses. So far I have come up with these two options which both have a similar price of $150 used. Sigma 170-500 f/5-6.3 Add a 2x teleconverter to the Nikon 70-200 f/2.8 that I already own. to make a 140-400 f/5.6 Online reviews for the Sigma say that it’s rather soft at 500mm. I know that the Nik…

A Nikon ZFC is compatible if I put the adapter z to f? Do I have to buy another d800 if I want to use the sigma 150-500? I am a beginner. This is one of my shoots. If I buy a new reflex I have to do something like downloading a firmware? Th…
