Better than very well actually and it’s rectilinear and not a fisheye. It tests very well in the few reviews I’ve seen. One possibility is the ‘14mm f2.8 Samyang multi-coated aspherical IF ED MC’ lens (also Bower/Rokinon).
Ptlens how to#
I have an a850 and the widest I go is 19mm and am also considering how to go wider inexpensively, yet maintaining excellent optical quality.

You don't say what camera you are using or rather what sensor.APS-C or 35mm? That makes a huge difference, of course.

PTLens has finally consigned Photoshop to the trash, where I have long wanted to place it.I'd really like to get wider in a single image, affordably.what do dyxumers think represents the most economical solution in relation to the angle of view? Take a good look at the handicapped parking sign before and after correction.įinally, perspective correction – here’s the picture I published the other day showing the correction of perspective using GIMP in PTLens it’s even easier.Ī slam dunk purchase at $25 and you can even make it use all four cores of your CPU if it has that many. Here are the before and after images, the latter processed in PTLens using the programmed settings from PTLens with no other adjustments: Here’s an example from the over-rated 24-105mm Canon L zoom which noticeable barrel distortion at 24mm as is clear in this picture:īarrel time – 24-105mm Canon lens at 24mm. When it comes to correcting more regular lens distortions, PTLens is in its element, as it has a large database of lenses with all the settings stored for you, whereas Photoshop has none – you have to do everything manually. As ImageAlign has folded and the application/PS plugin are no longer available, PTLens is a viable and inexpensive modern alternative. PTLens saves the processed file back into the image stack in Lightroom and is very fast, the preview reacting in real time as the sliders are worked. There is no practical difference, defishing rendering the field of view of a 12mm hyper-wide rectilinear lens. Here is the same image ‘defished’ in both ImageAlign (left) and PTLens: Here’s an original fisheye image of one of the bedrooms in Hearst Castle where I very much wanted to retain the ceiling in the final image: No matter – correcting distortion in the latter is child’s play using the slider. Many common lenses are programmed in though not, for some reason, fisheyes. I downloaded the PTLens application and installed the the programs (PTLens and PTLensEdit), making the latter the choice in Lightroom under Preferences->External Editing. As for chromatic aberration and vignetting, Lightroom version 2.0 and later does all I need, so I do not touch on that aspect of PTLens here. Perspective correction has been done in Photoshop CS2. ImageAlign does not work in PS CS3 or CS4. Up to now I have been using ImageAlign for de-fishing snaps on the 5D taken with the Canon fisheye and Photoshop CS2 (a Rosetta application) and for correcting leaning verticals and barrel and pincushion distortion from Canon’s poor wide-angle lenses.
Ptlens download#
It’s a free download permitting 10 uses, whereafter the price is $25 – a very sensible policy.

It comes in Mac and Windows versions on the Mac it runs in native 64-bit mode if invoked from Lightroom and is a Universal application, meaning no need for the buggy Rosetta application (which causes spontaneous reboots in Snow Leopard) and supports full 16-bit color TIFF and PSD file formats. Correcting chromatic aberration (color fringing) and vignetting – not tested here.Perspective correction (leaning verticals, etc.).PTLens was recommended to me by a fellow photographer and proves to be one of the easiest ways of fixing four common problems:
