According to the EU shop, that 2099 includes 350 in taxes.

The Adorama price does not include tax.

Keystoning






QuoteQuote:

In photography, the term is used to describe the apparent leaning of buildings towards the vertical centerline of the photo when shooting upwards, a common effect in architectural photography. Likewise, when taking photos looking down, e.g., from a skyscraper, buildings appear to get broader towards the top. The effect is usually corrected by either using special lenses in tilt–shift photography or in post-processing using modern image editing software.

To me, the best way to support Pentax is to use your Pentax gear to make good images and post them online (and not just at Pentax Forums).

Someone posted 3 RAW files made with the OM-1 + 150-600. Not shot under the optimal circumstances - very much "real world" - and I think the lens did OK.

Zásilka | Úschovna.cz

I opened the files with DXO PhotoLab 7 - there is no module for the 150-600 yet.

The Sigma 150-600 F5-6.3 DG DN OS Sports lens, which the OMS 150-600 is based on, fared much better in PCMag's review. Of course, these are singular samples.

When it comes to ascertaining the sharpness of a lens, I would prefer to view test results rather than images (although ideally both), because I don't always know the skill level and processing choices that went into the sample image. For things like bokeh, rendering, etc. of course I want to view "real pictures" ;)

With most cameras released over the last few years, there is usually only a small or nonexistent penalty for using electronic shutter. For example, here is the comparison of the Panny GH5 II...

Welcome back, and I hope the worst is behind you.

Over the last two years the vast majority of my photos have been made with a kit zoom, cheap tele-zoom, and modest portrait lens. There's so much that can be done with a relatively modest arsenal.

The original G9 seems to be very similar to the G9 II's mechanical shutter performance.

Some folks are questioning the measurements provided by Photons to Photos, though. What I've been reading is that maybe the problem is the combination of electronic shutter + high speed shooting mode, where the G9 II's "dual-gain" circuitry is bypassed in order to maintain fast burst rates. I haven't seen anyone put forth a definitive comparison, though.

This excellently-written article by @c.a.m might be useful to you: Achieving Better Manual Focus with the Green Hexagon - PentaxForums.com

For several years I shot long tele exclusively with manual-focus lenses. Really, it comes down to practice, practice, practice. Even on days when I wasn't out shooting, I would practice my focusing techniques on various objects around the yard. The more you dedicate yourself, the better your results will be.
