Essex Churches with my 'Shift' lens --
But I don't have a shift lens (one day perhaps), so I have to straighten them in software; is there one for K-mount APS-C? Philip (P.S. I think Shelley needs a slight clockwise rotation.) I have the Samyang 24mm TS lens which is very sharp and has proved excellent for buildings. It ideally ha...

It's Bee Fly Day!
That pile of triggers deserves a picture - my imagination is boggling! :shock: Bee flies are flies that mimic bees. Their larvae are parasitic on the larvae of specific species of solitary bees and wasps. They lay eggs in the hole used by a bee, when their larvae hatch they consume the bee larvae...

Willow Tree
Booked in and took a trip to St Fagans, the Welsh National Museum of History as it's back open but only to those who book in and then there's set numbers allowed in daily so its nice and quiet. Saw this tree that took my fancy with the way the light was hitting it. Pentax K1 & D FA 24-70mm 1. ...

Go With the Flow
hi Nigelk, i presume picture 7 is the photo you chose for the Gallery and it appears less contrasty (dark) than it appears on the example you have on this thread. It is just an observation , is there a reason for this Flan, you presume incorrectly. I walked past this field with the wife the evening ...

Some leaves with a Pentax 400 - 600mm mirror lens
These were taken with a K5 on a tripod. ISO 80, f8 @1/25th and 1/15th respectively. I'm slowly learning how to use this amazing beast. As with mirror lenses in general nailing the focus is crucial. I didn't get it quite right on the first shot - I could only see the rearmost leaf clearly. That...

Some leaves with a Pentax 400 - 600mm mirror lens
Impressive. They both work for me, but for different reasons. :D Why is nailing the focus any more crucial with a mirror lens than any other lens? Problems with seeing a rear screen are as old as photography. The original solution is still available , albeit a bit inconvenient to use up a gum...

Really like the first. Richness of colour and the focus looks damn fine to me.

Some leaves with a Pentax 400 - 600mm mirror lens
Why is 'nailing the focus' important? ... With conventional lenses, you can get away with a minor misfocus by, for example, sharpening it a bit more. With these it HAS to be bang on. There is no leeway at all and even with a long throw the tiniest movement will throw it out. You are right Aitch, gu...

Some leaves with a Pentax 400 - 600mm mirror lens
There are some terrible reviews of this lens but these pictures make me think it might be more to do with the photographers than the lens! Very nicely done. I assume the issue with focus is that with a fixed aperture you don't have the luxury of stopping down to increase depth of field, so nailing...

Some leaves with a Pentax 400 - 600mm mirror lens
Yes, you got it in one Kris. I often find myself reaching for a non-existent aperture ring! The downsides of this beast are, it needs a lot of light and its sensitivity to the slightest mis-focus. A Tamron 500 behaves very similarly. A tripod, bright sunshine and live view go a long way to super res...

Some leaves with a Pentax 400 - 600mm mirror lens
That's a nice selection David, unexpectedly good for long Mirror lenses (in my experience) - I've often found them to be on the "flat" side and I often struggled with nailing the focus too - but your skills have brought out the best 8)

Flower Studies
An unusual and interesting take of the dying flowers, were they focus stacked by any chance?

First roll of Infrared
I shot a roll of Rollei Infrared film using a 720nm filter and metering for ISO 6, taking two shots, one as metered and one over. I haven't got the negs back yet to check, but it looks like the ISO 6 was plenty, if not slightly too much. Here is one photo from the roll taken using my MX and a SMC ...

First roll of Infrared
Like it very much Kris, great framing and treatment - and converging verticals are fine by me, they even work quite well here. Thank you. You had me rushing back to Lightroom to check, but there aren't any converging verticals in this one. I spent some time setting-up the camera with a spirit leve...

First roll of Infrared
Which shift lens is it? The K28/3.5 apparently has a gelatine filter clip at the back: - not suggesting the filter might be easy to get though! In this case the foreground interest really adds to the image, well done for picking that vantage point. If I ever get my Intrepid 4x5 going, I migh...

First roll of Infrared
Thank you. You had me rushing back to Lightroom to check, but there aren't any converging verticals in this one. Oops. :oops: I have to admit my eyes were (are) playing tricks on me. What's more, I actually meant 'diverging'. :shock: I guess it's all because of that great composition - I am visual...

...again, super focus and sharpness - you're really nailing the "in flight" shots! Keep 'em coming ;)

A Colourful Character
Lovely bird and lovely pictures. As you comment, one would expect him to have a full set of tail feathers this time of year as well as a few more round the back of his neck? Probably had a fright with a fox.

Yesterday's cold start
Thanks for all the comments :!: David, the lens is the A*200mm f4 Macro, it my default back garden lens nowadays ;) Serge, your creative eye is matched by an equally creative mind, although now you've said it - I can see it too :D

Chasing Sunrise on the River Avon
Simplicity often rules - a lovely early sun as the dominant colour with the silhouetted grasses at the foreground complementing the soft, out of focus background - excellent 8)
