Early July , (2024), I bought one of these from a yard sale. It looks as though it has never been used... even though I'm sure it has seen a few rolls of film. They were ready to take $8.00 for it but I left $30.00. I will put a roll through it soon.

Thanks for this video! I believe that Retro 400S (my go-to infrared film) and Rollei Infrared (as well as CatLABS X Film 320 and JCH StreetPan 400!!!) are also the same emulsion, but I recently saw the Naked Photographer's analysis of Retro 400S and it seemed to be terribly pushed, so now I'm wondering if it isn't also, in fact, actually Agfa Aviphot Pan 80 too...

Minolta cameras were beautiful....at the end.

These videos are so clear and useful. Thank-you. I had just done my own testing with essentially your experiments from your part 1 and 2 and went looking for ideas for what to try next. For one box I got to white with restrainer and bleach but some papers are too fogged for even that. I now have ideas for my next experiments

are polaroids the most expansive fotos?!

Interesting series. If you bleach a photo you should re-fix it or silver halides can be an issue later on. I wonder if the tone difference was due to not fixing it after bleach.

Next time try this. Develope unexposed paper, bleach away all the fog, wash. Expose the paper to your image and develope, fix normally.

Now that explains why when I shot rpx25 at 100asa and stand developed on Rodinal I got 38 perfectly exposed negatives!

Very interesting... How would the RPX-25 IR capabilities compare with IR400?

I came here for the starwars jokes, and im severely disappointed. Beautiful camera btw

Generally interesting review. I love this film personally, shooting it at EI 25 and developing in Dokuspeed SL-N. Even with this dedicated low contrast developer however you still have to watch the SBR, treating it more akin to a slide film in that regard, otherwise highlights can quickly block up. I have to disagree with one point you made however: regarding there being "no industry standard" for measuring the resolution of film. This is incorrect, and there is a very well established such standard defined as lp/mm at a specified subject contrast ratio. Perhaps I misunderstood your point here and you were referring to a standard for the "megapixel equivalent" of film? If so then I would agree that is more open to interpretation.

Nice video! Its interesting that on my bulk Rollei retro 80, I dont have the name on the film. Only the numbers

I have my doubts here. The spectral sensitivity for both of these films tells a different story. While similar, they’re definitely not identical.

Good video thanks. I am a big Minolta collector (I also use the cameras very often I should add, I don't just buy them), also Olympus SRL and some Canons and Nikons as well as old Konicas and Mirandas. I usually watch videos of RUclipsrs commenting and giving their opinions about that analog world from not so long ago. There are many interesting interviews with very good information, as well as a lot that is not worth it. When it comes to Minolta, there is something that never ceases to attract my attention. When it comes to Minolta's proprietary system, the majority seems to have agreed and which to me seems not only boring but also quite uninformative. It highlights the fact that the flash shoe is proprietary and that fact alone makes it meaningless and points against the camera automatically and as a universal truth. To begin to argue with that plethora of detractors who did not take the trouble to see if that was really the case, I am going to argue the pros of that system and also comment on the suitability of a non-proprietary system. To begin with the only real advantages of a standard hot shoe is the use of other things that are not flash such as remote triggers or some other accessory that in general are not used by consumers since even if they have the same hot shoe the use of a flash per example Nikon on a Canon must be done in manual mode because automation is not supported. Minolta's proprietary system has several advantages over the standard one, it is safer and easier to use, but most importantly it gave consumers the ability to have access to wireless flash without having to purchase remote trigger systems. For example, with the Dynax 5, a large number of flashes can be fired remotely without using anything other than the built-in flash and that was already possible since the SI series. What's more, Sony flashes are even compatible with those models. I remember when the Dynax or Maxxum 9 was announced in 1998, most critics dismissed it as a professional camera that had a built-in flash without taking into account that this flash was for using the wireless lighting system.

Hi to everyone, Adox CMS 20, Easly our performs 45mp . Cheers

You're the only creator that has ever mentioned the infinity lock! Good on you ❤

Man, the Mandalorian edition is just the epitome of cheap consumerism. Not knocking the show, but it doesn't look like a $100 MRSP product, and if it weren't for the merchandising and sale price, it wouldn't have any appeal at all.

Thanks. Very interesting. I picked up a Dynax 3 and a Dynax 5 for A$15 and A$20 in 2006 when nobody wanted them anymore. I never new what that back AF button was for till now.

I feel pretty cheated having bought RPX 25 several times.

Would you do a review of the Sony easy choice lenses at some point in time? I might want to hear you review these lenses about. I am also picking up a DT 35mm 1.8.

Both the RPX25 and 80S are Superpanchromatic, the original APX25 was an Orthopanchromatic film. Completely different spectral response characteristics.

Thank you so much this helped me and now I know what to do w all my old fogged paper! 📸

Do you happen to know the formula for making your own restrainer? Thank you!

Very interesting video , very well explained (sonar history). I knew that Contax got for its Contax yaschica film line a 85 f2.8 but I didn t know there was the same for Sony A. I saw one on a 2 nd hand market for less than 100€ and so I ordered it just after seeing your video. I will compare it with my ..FE 85mm’f1.8 and resell the one I love the less.

thanks for sharing

Wow

I guess it is the light wight that is also appealing. I have the canon 85mm 1.8 that stays at home as it is weighty to carry around.

Excellent review, superbly delivered.. will break out my 5 and and FP4 shoot something tomorrow. Have subscribed. 😊

Svaka cast i najbolje objasnjenje na svakom videu ✌️

Ok fine I only saw part 1 And nice comnent. Yes it can be nice with not perfectly white base!😊

Possible to make a bit darker copy and then bleach the fog. Finally use selenium toner to get good contrast! Used that method on old orwo paper that got lovelly tone to it. I use neutol wa developer witch is slow and I suppose already has some restrainer. Difficult with hard working dev as dektol. Everything happens allmost at once. Azo paper seems to have best shelf life! I have a batch from 1947 still going strong. No need for additives. But this is a contact printing paper and is so slow ( to slow for enlarging).

what about diluted d76?

Late to the party but I really appreciate you doing this. I was aware that RPX was manufactured by someone else but this is nice legwork.

The RUclips algorithm recommended this channel to me and I subscribed immediately. I am also a fan of Minolta (I have several Dynax and an XG-M) and Sony A-mounts (at the moment I only have an A-100 and I really like it). Your in-depth analyzes on lenses have been very helpful to me. I look forward to seeing more videos of your journey through film photography. Thank you!

How do these hold up in low-light environments? Which one would be more reliable for taking pictures in dark areas with artificial lighting do you think?

I love the Sony translucend mirrow cameras

Iike film and digital the more older is best

The older one is best is been always the more vintage the better made.

Very informative video, thank you.

the only reason I have some Retro 80s in the fridge, because I wanted to shoot some IR and the Retro will give some wood effects if shot through a 715 nm filter. Has anyone checked, if RPX25 also offers the same results if shot through such a filter?

I have not used this camera but hear nothing but good things about it. It's a minolta if it's anything like my minolta X-700 That I have solely used used from 1987 to this day without any repair needed it will just keep working with that beautiful minolta color.

This explained lots now please tell us more about Rollei Retro 400S. Thanks!

Nice comparison. I have both RPX25 & Retro 80S in 120 and was comparing the datasheets the other day to see their IR sensitivity, and noticed they were pretty similar, although Rollei rendered the spectral sensitivity charts differently, making them look different, which I thought was odd at the time. Too bad my last roll of Retro 80S had pretty severe print-through from the backing paper :( Will have to try out the remaining 80S & RPX25 and hope they fare better.

What a solid review! Love the format, very informative and so easy going, keep it up dude!

I'm from India, Can I use this Lens for pigeon eye Photography???

Love when I search a video and there's only one video on RUclips about it, I've seen a lot of Minolta lenses on Sony videos but thanks to make the only one that uses Sony on minolta

The 660 all day long.

One thing to keep in mind is that the 660 is a very old camera at this point. I have one where the light meter does not seem to work correctly when I'm using the flash taking pictures as you did in this video. My backgrounds with similar differences come out almost completely black. That is only a guess my other assumption is that maybe what camera is stuck on a fast shutter speed. I'm aware many old Polaroid still look perfectly fine and I have a few.

Informative video. Thanks for sharing. Interesting you have your Polaroid camera with a Kodachrome sticker on it. Kodak tried to make their own instant film camera. It was actually fun to use and I thought the photo surface was better. Plus one was able to peel away the chemical layer and just have the photo. Unfortunately for Kodak, they were found to be infringing on Polaroid's copyright and they had to pull their instant camera's off the market. My mom might still have the camera in her closet. And so it goes...

Thank you for all the work and information put into the video. Loved the introduction, a bit saucy and certainly funny. What a stunning film. 💚 23:10 Myself think be interesting to see Copex Rapid stand developed in FX-39 II, however, I am in the states and got far too much to do as it is...
