broken lens?
Not very good at all. At distances such as even at f4.5 there should be enough DOF to cover any slight error, but this is just not sharp at all. I'd chuck it back from whence it came and order a Pentax one. I know you'd expect me to say that, but it's issues like this over the years that have led...

broken lens?
I really like the Tamron 18-250 as a walk around lens but it is not fast enough at times (I have also just sent it back to Tamron to be looked at and hopefully fixed). I was hoping I could use the Sigma 17-70 as a general purpose faster lens and only move to the Tamron if I wanted to go longer than ...

Shots From Cadiz
I palyed around with hdr a while back, and quickly lost interest. While I had some good results with low light, bad weather, and nightshots, I find the daytime shots come out too flat and artificial for my tastes. they are ok esp#7 the statue image up top was the only one of these I'd have tr...

Shots From Cadiz
I think it will only be a matter of a year or two, before we see sensors and in camera processing, that will make a single click, true hdr, shot right out of the camera with tonnes of range. while that may make for some fantastic images, some people, especially guys that have had a love affair wit...

Problem with the gallery.
I would guess that having seen how successful the competition and Your Photos threads were they were trying to enhance the experience. Successful?? Hmmmmmm, I wonder. Of course for all the regulars participating active on this forum it was and still is a success. But looking at the big picture (60...

My First Sunset
I like 3 and 4 the best. They are difficult to do well as George says, simply because they are so popular. I like sunrises more - they may not have the spectacular colours of a sunset, but they tend to have more atmosphere to them. Try taking sunsets with the sun behind you too, to capture the gold...

My First Sunset
Only work done was a bit of straightening (I always seem to have that problem) and some contrast. I hope you get to at least spend the winter in Spain - moving back to the UK in winter strikes me as a depressing prospect. Not that summer has been that different to winter this year, just a tad...

The fly
Hi, I also have just purchased this lens 2nd hand for a very good price. Have not had time to use it as yet. For this type of shot did you use tripod, lens/camera manual focus and lens set at full 1:1 with F stop auto?. Superb shot Clarky. Cheers.

SunSet USA
I also like the first and third pictures. In the first it's the vibrant yellows in the lower sky that draw my eye, in the third the muted oranges contrast well with the silhouette of the pelican (would have done well in the "alone" competition a week or so back). In the second shot I don't think th...

'Gerald' the Gull
Thank you. The lens was the DA* 300, handheld on a floating pontoon. My Sigma APO is a very old manual focus version and the need to set a figure for the SR, as you change focal length is a bit of a pain, so I do not use it very often :!:

My Sigma APO is a very old manual focus version and the need to set a figure for the SR, as you change focal length is a bit of a pain, so I do not use it very often :!: Oh, am I doing it wrong? I presumed you just set the maximum focal length and then fired away all through the zoom. I set my 70-...

It's a very steep learning curve....... It is, very. As you've no doubt realised, it's the focusing that is a complete nightmare. The tiniest, tiniest error will give you shots that are slightly out of focus, as with this one, which is nevertheless not at all bad as a first go. You need ver...

From my wanderings this week
I much prefer Andy in colour :!: No. 2 - excellent. I find the items of text (varying in degrees of out of focus) a distraction in No. 3, but would agree that some text is needed.

Andy Abrahams, X Factor
Roy, To be clear, I use the flush mount Pentax adapters - not the inexpensive flange type which add length to the mount and we lose the ability to focus on infinity. I don't do anything to the M42 Lenses at all. I remove a flat little tempered leaf spring from the adapter so it won't lock i...

Beetles, dragonflys, a Swift, a lizard and a flower
If anyone can tell me the names of the beetles I would be grateful. Tamron 70-210mm In our house last night. Me trying to manually focus on a Swift ... took about 20 shots, nailed one. Tamron 90mm mf f2.8 macro
