i agree about the mirror lens, they can be great.

i use a Tamron 500 and the biggest problems are due to light. they do like it to be bright, not just for shutter speed, but also for image quality. they tend to look very flat on a dull day even with enough light for a fast speed. oh and the focus range is tiny! it is the narrowest f8 ever.

also... the Tamron has a long focus throw, it's a wide lens and if you're going for a moving target it's a pig to focus qhick enough. attaching a ship's wheel might be a good idea.

however... for nature reserves where you're in a hide, looking at wildlife on a lake or scrape, or on the coast, it's a great lens to have.

my main lens is the much-maligned Tamron 70-300 which i have had no problms with!

pm sent about the tamron 90

thanks guys.

I tried the in camera editing, but no joy.

i did transfer the files to the laptop, but can't open them, even with preview. looks like those 5 shots have been lost.

That's my first duff card, i get them from 7dayshop - usually get the unmarked ones, but this time went for some fuji ones - and never had a problem - that'll teach me to switch brands.

just taken some more shots to see if any of those die and i'll use a different card from now on.

thanks again.

Last week i had the first instance of a dodgy memory card.

It was in my k200d and out of 200+ shots, five were corrupt. the odd thing is, they show up ok on image capture (on a Mac) and also on the screen on the back of the camera. when i tried to upload them to flickr they didn't go. they are taking up space on the cards equivalent to a good shot, but iphoto and pentax browser software says the file type isn't recognised.

any ideas or are the images gone?

cheers

i use manual extension tubes with a 50 1:4 and a 28 2:8, the latter cost about 20 squids on ebay. i also use them with the Tamron 70-300 as that has an aperture ring.

the 50 is a good lens to use them with...




although, at times, you do have to have a very trusting subject!

hi and welcome... i second the suggestion for Sanyo Eneloops. use them in the k200 and k100 and they last for ages

very tricky.. so i'll cheat

1) everything by Robyn Hitchcock (including Soft Boys)
2) Eveything by r.e.m.
3) in the aeroplane over the sea - neutral milk hotel
4) hollywood town hall - the jayhwaks
5) concert program - penguin cafe orchestra

oooh, snakey!

lovely shot and snake

lovely shot.

i was chatting with someone yesterday (a c***n user) about Tamron lenses and the 70-300 in particular. on another forum someone had asked about Tamron and people said they are good "apart from the 70-300". I've never had a problem with the lens and most of my shots are with the lens. this shot proves what a great bit of kit it is. i do suspect some snobbery - it's not expensive, therefore rubbish! i also suspect that other makes of camera users might not like it as it won't have shake reduction!

could well be mallard hybrids or domestic ducks of some kind.

i've seen some lovely mallard 'mongrels', black and white, tan, almost all white - and they have had chicks, most of who are 'normal' coloured.
