Reeflex 240mm telephoto lens

I would not expect too much, if the sensor stays as tiny. In my S24U I cannot see much benefit in the 50 MP for the 5x

That's a clear difference, thank you.

You're right. But the 12 MP sensor of the current Iphone 5x lens doesn't allow cropping, or, should I say, relies almost entirely on digital cropping, with so-so results.

A 50 MP sensor would allow "optical" 2X crops with good if not very good results. At least, that's what I'm seeing with my Pixel 9 pro.

Some wildlife photos:







And some not-so-wild life.

As said before, it looks very good and the benefit is that you don't have to crop from 12MP image. Also, 5x is way better than having a long gap between standard (main) lens and telephoto (like I have on S23U). Talking of which, I do believe 5x + this add-on lens IS sharper than 10x I have. I am generally OK with my 10x but even in a very good light, there is a lot of noise as the sensor is very small. Apple sensor is a fraction larger (1/3 vs 1/3.5 on Sam) but the processing is better and the 5x lens is brighter (so with this TC I still believe you are better off when we talk resulting f number).

The only question if how it perform in low-ish and low light? Samples appreciated.

These are darn good. Thanks for posting

Here you go. Both are hand held.

Thanks,

it appears it is a pretty good glass not causing any additional problems with bright light sources and not robbing too much light. Impressive

Wouldn't a 6x telephoto lens for the main camera bezter than a 2x for telephoto? With the sensor being much larger and having more crop Potential through Megapixels that should work out better - if the 6x is as good optically.

That's unlikely. I doubt a 6x converter would be any good. So, using the 48 MP large pixels of the main camera would not compensate for a mediocre 6x lens sharpness.

I speak for myseif: when I use long FLs on my DSLR, it's because I want to shoot some detail. And that's why I want excellent sharpness.

It's different if you use long FLs to "compress" the image for landscapes.

Just my opinion.

Which is the main reason that I bought this lens. And if the rumors are true that the upcoming iPhone 17 Pro/Pro Max will be receiving a 48 MP sensor for the 5x (120mm equivalent) telephoto cameras, then my phone camera will likely be “good enough” for almost anything that I care to shoot.

Last night’s full moon, shown uncropped.

The specification is a lie and the quality of the images in this post is terrible. This is nothing more then a duplicator of the 10Mpx 5x original iPhone zoom.

Then they follow it with a guy trying to prove that 10Mpx is good enough for large prints.

All of this product is just a scam!!!!

I looked at the Reeflex product page and I get confused. The manufacturer claims that it is a 10x magnification lens but it only gets to 240mm when paired with the "5x" camera. So it either is a 2x lens or it goes up to 1200mm.

I guess its a 2x and the "10x" is a false claim. For a 2x magnification lens it is quite expensive and I wonder if it has any benefit compared to just cropping the 50MP image. The aperture will be darker by 2 f-stops and resolution will probably also suffer.

Can you see a better result with this 2x lens? I would be surprised if so, even in bright sunlight.

There is some false assumptions/misinformation in this thread. When a 2X teleconverter (correctly referred to as an auxiliary lens) is attached to the front of a lens, the resulting loss of light is generally less than ⅓ of a stop and mostly the result of reflection from the glass surfaces. However, front attached auxiliary lenses, if high quality multi coating of all surfaces, and high quality glass is used is reduce aberrations, the light loss is minimal and the quality of the main lens is preserved.

A 2x teleconverter magnifies the image by 2×, effectively doubling the focal length of the lens. A 100mm f/2.8 lens becomes a 200mm lens. But it also becomes an f/5.6 lens in terms of effective aperture.. Aperture (f-number) = focal length / entrance pupil diameter. When you attach a 2x teleconverter the focal length doubles, but entrance pupil (the apparent size of the aperture) stays the same. This is just physics and the Inverse Square Law.

A front-mounted auxiliary lens optically magnifies the image before it enters your lens. Think of it like reading glasses for your lens. It changes the angle or field of view without altering the internal geometry of your lens. The lens’s focal length and aperture ratio (f-number) stay the same as far as the camera is concerned.

This is a screw-on (17mm mount) lens optimized for the telephoto cameras of the iPhone 15 Pro Max, 16 Pro & Pro Max, and the Samsung 24 Ultra. It will deliver a 240mm-equivalent image at full resolution, and comes with a couple of magnetically-attached 200mm & 300mm macro filters that provide an easy-to-carry macro capability. I’ve only had this lens for a few days now, but my first impressions are very good.

The macro filters are a welcome addition.

Thanks for the time you put into this thread. In info I’ve read about this lens, I saw the reference to needing to use the Reeflex camera app to take the photos. Did you use that or the native app. Also, Adobe has released the beta of its Project Indigo app which is yielding quite good photos. I’d be interested in comparison images from all three camera apps if they work with this lens.

You’re welcome! But yes, you have to use the Reeflex app with this lens. Because Apple’s camera app can’t tell that there’s a lens attached, and switches away from the telephoto camera. But the Reeflex app is very capable.

I did a little comparison between the Project Indigo beta app and this lens/app combo, including an attempt to combine the two. You can see it here:
