It is difficult to judge bokeh of a lens by a single image, not even knowing what the scene looks like. The background looks smooth, but maybe any similarly long lens would make it reasonably...

I don't think the aperture shape is the main thing regarding bokeh. It is true that the aperture shape is sometimes obvious in the bokeh, but I think the main thing is in the glass. Several lenses...

In principle, TTL auto flash should automatically take extension tubes into account.  There is a catch that TTL may not be what what one would assume because various intelligent-TTL variants are a...

Enfuse? What kind of stacking?

You can use a ladies mirror ;-) That's what Lim's Easy Bounce and Lightscoop Deluxe actually are - with some plastic to hold in place, and they fold flat.  A kleenex or a cut white translucent...

Thisone may be useful. But notice it tends to lean on the flash head. Then it is the same as a pinpong ball or fujifilm canister: too small to diffuse much. This works in a room by spreading light...

The Marumi achromats are supposedly good quality too, but these days nobody posts serious assessments of such stuff, the 250D is a more reliable choice. Not much point in getting a +5 if one...

Tnx for your detailed assessment. I already ordered one before you posted :-( Will see what I will do. Maybe the firmware is flashable via the mysterious mini-USB port. I've noticed some of the few...

D90 doesn't have the aperture sensing tab either.  But some of the older lenses are easily chipped ($30 + epoxy glue). You must google up your specific lenses, because dremeling etc may be needed...

The 250D is certainly a good lens. If you want a (relatively) long working distance and strong background blur, it is best to use the long end of the zoom and the weakest diopter achromat that...

More importantly, with less background matter being obscured by blur of the foreground. Mind one could take the same large number images to exclude the "not in focus" issue.  Some of the blurred...

No "generic" setting. Use it if you shoot JPG and want to lift shadows. Don't use it if you want to have traditional high-contrast rendering. You may also want to use it with NEF if you like what...

Yep ADL xtra-high is known to underexpose up to about a stop (scene-dependent), and XH2 is an even stronger level.  If you shoot NEF and convert with Adobe, and take care of highlights by adjusting...

Users of many cameras have found LV histograms to be relatively inaccurate compared to in-camera RGB histograms. The latter, in turn, may show small blown areas only upon zooming in, and even using...

It comes in several mounts, one of which is legacy Nikon AF (non-electrified, similar to Nikon tubes).  Notice some folks have taken the glass out and use it as a variable extension tube (might...

Most current cameras with CMOS sensors have electronic shutters of the "rolling" type. But the scan time of this shutter is relatively long, much longer than the shortest exposure time, and also...

In normal OVF mode, you can take a picture, check the preview pic and RGB histogram, adjust exposure, retake the picture.  I'm not certain about LV, haven't got the D5200. I guess you can't eyeball...

This looks like longitudinal (axial) CA, which is more difficult to fix than lateral CA. Stopping down the aperture may reduce it. Any attachments used?

This is not always the case. In some conditions, the EVF indeed acts as "night vision", boosting brightness with ISO. But at a certain point, at higher magnifications and/or lower light, EVF image...
