I've been using Aperture on an iMac i7 for several years and am thinking of upgrading to Lightroom; I'd appreciate advice/answers to a few questions:
1. I've heard Lightroom gives better highlight recovery than Aperture on certain micro four thirds RAW files. Does this include the Olympus OMD E-M5?
2. Is the noise reduction better than Aperture's?
3. I've read that there's a one-touch facility for correcting lens aberrations such as vignetting and barrel distortion. Is it necessary to load lens profiles and if so how is this done, or are they downloaded automatically or supplied as standard?
4. Is there a facility for correcting perspective distortion such as converging verticals, either as standard or by downloading a plug-in such as PTLens?
5. Is it possible clone one, repaid, burn, dodge, polarise etc?
As a recent, begrudging, migrant from Aperture to Lightroom I'll chime in.
I wouldn't necessarily describe moving to Lightroom as an upgrade. Some aspects are superior but others are inferior.
Noise reduction is far better than in Aperture, with controls for luminance and colour noise.
There is indeed one-touch controls for all the lens aberrations you mentioned. Lightroom has a number of built-in profiles for lenses (all of my lenses were automatically recognised) and Adobe offers a free tool to create your own profiles. Lens correction controls also provide manual control of converging verticals (and horizontals), chromatic aberration and colour fringing. Best of all, they're non-destructive so there's no need to round-trip the photo to PTLens.
Disappointingly Lightroom doesn't have a clone tool but you can create circular patches which can be set to clone or heal. Dodge and burn can be brushed in but you'll have to find your own way to fake a polariser effect.
