    Re: Wide Angle Lens

    although i recommend using a UV/Skylight on a lens at all times to protect it,
    i don't on a wide angle. i have found that it tends to make sides soft on length of the rectangle and could cause big problems especially with group shots.

    Audrey, I think that sounds exciting. I have not sen the area before. Maybe I will get lucky and you will share some of your captured memories with us here on DPnow. Have fun...................

    I don't really think I know when to use it.

    I used it in a fairly long distance shot of fishermen loading their catch, whereas my husband used just say 35mm equivalent and got a lot better pic. Also, I thought it should be used, say for landscapes to get more of the picture in, but now I think I see people using WA lenses on buildings, fairly close up to get more dynamic angles or low angles on cars to make them look more arty.

    What should WA lenses really be used for?
    I learned how important it is to have a wide angle lens while I was on vacation in Philadelphia PA. They have someof the narrowest strets I have seen anywhere I traveled. Thewide angle 10-22 made it possible to fit the buildings I wanted to photograph into the viewfinder without being able to back up any furthur. A wide angle serves you well when in a small room where you have say a group of people you could not otherwise fit in the picture. I like the effect I get using a wide angle when shooting tall objects such as sky scrapers.

    Re: Wide Angle Lens

    I have not as yet had time to look through the contents of the site. When finding this thread I realise the wealth of information that must be contained in dpnow.

    Anne and I recently purchased an 11-22 (22-44) for our Olympus E-510's. This thread in just a few minutes has given us more food for thought. Thanks.

    Regards. Barr1e

    I'm shopping for a WA zoom for my Nikon D50. Would you buy the Sigma again? If not, what might you put on your short list to investigate? Thanks for the (free) advice; and I do remember the old saw: you get what you pay for!

    Re: Wide Angle Lens

    Thanks for that information Devilgas. My camera and WA lens don't show the markings, but it helps me to know where to actually focus and when to use the lens.

    I have never used it much and keep taking it on holiday and still not using it. I must get out more locally and give it a try. It's a shame to have these lenses and not use them.

    In your images, would you focus on the nearest part of the scene or about midway?

    The last one, of the rocks, is so clear so I wondered if you had focussed on those.

    Is there a special rule when focussing.

    My Canon manual just says it must be kept at Wide Angle (not zoomed). I did once zoom in and the image had a vignette. It was the first time I used it and I thought it was broken.:

    Another thing, is there any way of telling when an image has been taken with a wide angle lens. I hear Judges say "Good use of the WA lens," and I wonder how he knows. Also, can you tell from the Exif and if so what would you be looking for?

    If you have a look at my avatar, I think I remember using a WA lens on that, but I can't see in my Exif.
    focussing - typically you'd set your focal point 1/3 of the way into the scene / area you want in focus. the rule of thumb is that at a particular focal point, your depth of field is split 1/3 in front of the focal point, 2/3 behind the focal point. so, say the lens settings gave you a depth of field of 30m and you were focussed on an object 20m away. the limits of the areas of the photo in sharp focus (depth of field) would therefore be 10m 40m (1/3 of 30m in front of the focal point [20m - 10m] and 2/3 of 30m behind the focal point [20m + 20m]).
    manual focus lenses used to (and probably still do) have marks adjacent to the focus ring to indicate depth of field for a given aperture. when i used to use my fathers old minolta x300 slr on rallies, i never focussed through the lens, but always used the DoF marks on the lenses.
    with digital it's more difficult as AF lenses typically don't have these markings. canon dslr's have an aperture-dof setting (Av-dep) whereby you tell the camera what you want in focus. it then sorts out the aperture setting for you.

    no real other special rule when focussing other than taking into account that a WA lens / adaptor will give a greater depth of field thanks to the laws of physics. taking my sig 10-20 as an example, (from memory) if i manually set the focal distance to 1m, the aperture to F8 and the zoom to 10mm, then everything from about 1ft to infinity is in focus. makes shooting with that lens a no-brainer!

    exif - for bolt on wide angle adaptors, the info is unlikely to show in the exif. for a dedicated WA lens, then it should show. e.g. with the sigma 10-20mm on my canon it'll accurately report the lens settings in the exif

    judges - you can typically spot a WA shot from the perspective distortion and the amount of the scene that is visible etc. the photos that stephen posted above clearly show this exaggerated perspective

    Re: Wide Angle Lens

    Thank you Stephen....the effect you explain is exactly what I would give my right arm to achieve! That kind of photo I think I could only aspire to in another life! It seems there are Wide angle lenses & there are WIDE ANGLE lenses....the more ya pays....the bigger & better they are! Your picture of the steps looking over hill, dale & yonder is fantastic! One can almost feel the atmosphere of solitude, sound of the wind & smell of nature! It reminds me a little of the view from the church opposite my sisters home in Devon!

    Re: Wide Angle Lens

    I guess I would like some advice, if theres anyone willing out there to help! I would however need to know specific to Panasonic Fz30 & the person who really knew his oats, (George) no longer participates in the forum unfortunately! I know there are a couple of people that have/had FZ20 that possibly could advise which ratio I would have to use when wide angle lens used! ie 4:3 3:2 at 5 Megapixels or 16:9 at 3Mp? Would going right down to 3Mp cause huge quality loss? If using for landscapes, would it be better to use a telephoto lens rather?

    Thanks again. That little camera icon didn't used to be there, but I didn't look today - I assumed it still wasn't there.

    By zooming in to 100% to various parts of the picture, it is really delightful to see so much activity and I suppose that is what I saw on the day. I wish I could have made a better capture. It is the sort of picture I would have liked to print as it is so colourful.

    BTW can you see the Exif because I haven't been able to see the Exif on anyone's pictures (even my own) for months.
    Yes all the Exif data is there if you click on the little camera icon

    Thanks so much Stephen. I have learnt more in your two minute tutorial that I have learnt in 10 years. You have explained and illustrated it so well.

    I am attaching the image mentioned previously. This is unadjusted. I have since cropped it, but I could have got more detail by taking a couple of shots and making a pano.

    I see now that I was not using it correctly.

    BTW it's good to see your images again. They still look stunning.
    Thanks Audrey.
    Yes you are trying to use the lens to capture the whole scene, yet by doing so it seems to me you are not really capturing what the scene is about, the hustle and bustle of the river side market, with throngs of people and boats busily coming backwards and forwards. Perhaps what you needed to do was zoom in on the action and therefore crop out the unnecessary water area, which is the by product of using the wideangle. I've attached a crop of your image to show what I mean
