Not if you have a shift lens. Unfortunately they're beyond my bank balance. Shooting wider & cropping is usually an effective alternative now resolutions are so high.

It doesn't have a zoom ring because it's fixed focal length prime lens (60mm) Manual focusing is via the wide ring nearer the front of the lens (or by varying the camera-subject distance - often a ...

The lighting also illuminates the rear of the interior mirror, so it's unlikely to be purely inside the car. Lighting the inside from a suitable angle would make sure any reflections are not coming ...

This would have been the problem with my 10mm/2.8. The error in my adapter meant I had to turn the focus ring nearly all the way to minimum to reach infinity focus. I think it left the real ...

I've never met a lens that doesn't work with diopters. Extension tubes will have minimal effect on long focal length lenses exactly the ones diopters work best with. I have both, in my everyday ...

Loss of contrast from internal reflections is a possibility with some adapters. I've heard that sometimes a simple circular baffle from black card can prevent the issue, other times lining the ...

The single element type were adequate for film when only printing to 6x4. In todays world any camera is likely to show their problems. Raynox's less severe models (DCR150 at 4.8 diopter & DCR250 at ...

I've had similar issues with several of my adapters, it's not usually that difficult to shim the short ones to much closer the right size. I've reduced the error in my MFT to A mount adapter from ...

Just about any mirrorless camera will have adapters available to use Nikon dSLR lenses (unfortunately only in MF for most) . Most of them will also allow you to adapt hosts of other lenses that ...

If long exposures isn't a problem for you then just using a more restrictive filter should give IR results from your existing camera, a 850nm should be OK. My cheap & cheerful '850nm' transmits ...

On my mirrorless cameras I often us special MFT to EOS adapters along with EOS to lens adapters. Giving me a range of focal reducing adapters, a range of extending adapters & a range of tilting ...

Indeed in Macro photography DOF is a function of effective aperture, magnification (at the sensor) & circle of confusion (not actually sensor size). If the same final output is the same size (not ...

Given the state of the camera $50 seems rather a lot. Checking e-bay there have been clean working examples sell for less (body only & occasionally with a cheap zoom). I hope you checked the ...

Others to consider include T2 & adaptall2 both adaptable to nearly all SLRs. Medium & large format lenses are also possible (but expensive). Longer focal length enlarger lenses can also be used, ...

Given the number of pedants jumping on the ISO doesn't effect exposure bandwagon (True but not helpful) I'm surprised that no-one has pointed out that none of your variables affect the lighting ...

I'd suggest a Raynox. It's easier to take on/off than extension, and should work nicely with your macro lens. The DCR150 (a little less powerful than it's 250 brother) should if my calculations are ...

Unless the focusing system in Sigma DSLRs is very different to other DSLRs, From a theoretical standpoint AF shouldn't work well in IR. Most lenses bring NIR to a focus at a significantly ...

The shots in the Original post show glowing bright foliage so plenty of IR is being recorded. What were the skies like when the photos where taken and where was the sun when they were taken? If ...

But as Alan's reply shows applying that logic gives you 8x. It's not what is usually described as magnification in photography - which is usually the image size/subject size and is highly dependent ...

The Raynox DCR-150 is 4.8 diopter so not quite as powerful as the 250, so gives more working distance when focused. Magnifications of all such supplementary lens systems depend on the focal length ...
