Macro but which one.
Reversing rings work well, but are a bit awkward as you lose the aperture contacts. I was lucky enough to find a set of extension tubes second hand that have all the correct electrical contacts for the aperture, these work brilliantly. Also, you may recall threads on here a few years back about bu...

Replacement standard zoom
I've had a look around the bazaars, keeping an eye out for the Pentax WR lenses but also some of the sigma line. Sub-£200 Another 17-50 f/2.8, this time from Sigma - large (with a 77mm filter thread), sharpness is even across the frame but not exceptional (better than kit), HSM, not WR I've foun...

Cheap lenses for portraits
Wide aperture lenses have very little depth of field at wide apertures, so focus is tricky to nail sometimes. The tiniest bit of subject movement can move the eyes out of the point of focus. I think the obvious choice is the Pentax 100mm f/2.8 macro lens. If you need to soften it, that can be don...

Irix 15mm filter size
So I was about to buy it when I noticed the gigantic filter size. I should add another 100 pound to buy a nd filter. Thoughts? Honestly who cares about that aperture :(

Irix 15mm filter size
For a lens of that quality wit filter still cheap Pretty much. It's a fantastic lens. Depending on what filters you need and how often you use them, you may want to consider using in body functions to replace them. If it's for regular use, then it's a no brainer to get a filter or two depending on...

Nd filter (6-10 stops) are still essential for very long exposures

Irix 15mm filter size
No, they safe your shutter from overuse, you can go up to equivalent of hours of exposures using the composite mode. Way over what you would be able to achieve with a 6-10 stops. I can go much beyond my 16stop ND with it; results are practically noise free and if you have an SD card large enough t...

Irix 15mm filter size
I haven't tried lately to use the multi exposure, but when I tested it a long time ago, I remember I could clearly notice that it was the result of stacked expositions. I will test it again in case I remember wrongly.

Though I dont do much landscape work. The point of the filter size on the Irix and Samyang lenses had not gone unnoticed..

Irix 11mm Firefly
There's a review on Youtube (not the Pentax version.) Seems pretty good. Looks like the lens hood is permanently attached, so no good for square filter systems.

There's a review on Youtube (not the Pentax version.) Seems pretty good. Looks like the lens hood is permanently attached, so no good for square filter systems. Given the field of view I'd expect the filter system would have to be extremely huge! One's quite likely to include one's feet accident...
