Anyway once again thanks to all -- I think we've done enough now on this topic.

Sorry, well yes, I have now

I was a photography enthusiast (and still is sometimes when I get the time). I only have my old and trusty Nikon D7000 and a Fujifilm X-T200 mirrorless for light packing. I love my Nikon lenses so instead of buying lenses for my X-T200, I just purchased an adapter so I could use my Nikon lenses with it. Everything will be manual though because it is not electronically compatible but I shoot manual most of the time anyway.

Below is my Fujifilm X-T200 fitted with a Tamron 17-50mm f2.8 for Nikon (my all-around lens) and sample quick shots I took with it.

I understand fully what you mean, I used to use Minolta in the film days and loved the lenses for their Interpretation of colour as well as clarity When the change came to digital I chose Sony as they used the same lens mount as the Minolta. [Having bought the Minolta Brand]

Over the years through various moves of home the Minolta lenses I had were misplaced, but I have managed over the last few years to obtain a small selection of Minolta Lenses, including an F4 Beercan 70-210 mm and my latest acquisition an F2.8 100mm Macro the great thing about the old lenses is they are not Plastic but Metal, [even the lens hood on the Beercan]

Hi folks

I still use regularly a trusty Canon T-90 at times -- especially for B&W Infra red -- it's still possible to get IR film stocks stocks and an old fashioned "Developer tank" can be used for developing the film -- I started off being able to load / unload film stock in tiny cupboards (I think the "Yanks" call them closets) -- covered over with black linen for light proofing . Those old 35 mm developer tanks were (and are) brilliant if any of you ever have to mess around with messy chemicals -- that's one area where digital photography has made the life of photographers so easy -- but years ago my first time in an old fashioned darkroom I still remember the wonder of a photo appearing like magic on the paper after developing.

For wild life photography -- using film stock (incredibly hard to get hold of) using a T90 with an FD400 mm 2.8 lens really can't be bettered by any modern DSLR -- although you almost need a golf cart caddy to carry around that lens.

Works with the FD->EOS adapter on a Canon EOS DSLR too. !!! although stop is 1.25X lower!!

For Zoom on a Canon I thought the old Sigma 17-35 MM was good for architechtural stuff (If pan and tilt lens not available) and for general purpose a 35 - 128 mm zoom good too -- although as I said where possible I like the prime 50 MM 1.4 lens.

Anyway G'd night folks -- and if you like footy -- in spite of the "Nastiness of Qatar" the matches so far have been enjoyable. @barman58 Loved Wales last grasp penalty to draw with the USA !!!!

One little question to those using DSLR's or other "Standard cameras" -- Lens caps are pesky little things that can magically seem to get lost etc -- any tips for ensuring you don't lose them. !!!!

One of the main advances that digital has brought is the sensitivity of the sensors in modern Cameras, and of course Phones. where as in the days of film you would require large and heavy lenses to provide enough light to keep shutter speeds up to a level to prevent shake due to the relatively low ISO, [or ASA], speed rating of film.

These days modern digital sensors will give acceptable images at anything up to 5000 ISO, [and beyond], equivalent so smaller lighter lenses can be used. Also the various shake reduction technologies that can be applied to the sensor means that the same image can be achieved at a muck slower shutter speed. There are also the advances being made with post processing software, noise removal and general possibilities for detail recovery, is getting to amazing levels, and we are now seeing AI being used to speed up the process tremendously.

A lot of these technologies are also being applied to Mobile phone cameras which can result in these outperforming what could be expected of their small often plastic lens and tiny sensor

Zooms have their place but if you have the time then you can't really beat a prime lens whatever its focal length because using a Prime rather than a zoom makes you think when composing the shot and at wide aperture you definitely need a tripod !!!!

They both have their own pros and cons. Prime lenses generally tend to produce sharper images with less distortions and can get better results under low lighting conditions even though combining a zoom with HDR and processing in software certainly narrows the gap about lighting conditions also including in architectural photography. Still nevertheless, differences in image quality between zooms and prime lenses grow smaller as you go up in price so, even in the professional segment, cost can become the more dominant factor. Prime lenses are more compact, more lightweight, and the list of advantages still doesn't stop there. However, in mirrorless digital photography, thanks to advanced image stabilisation mechanisms you don't necessarily always need to use a tripod, and, if there's too much wind, a tripod will shake so hard that you might want to rethink your whole strategy anyway. There can be a lot of variables at play.

Photographers who blame everything on the tools they use are bad photographers. To clarify (literally...), nobody here has claimed that a phone can outshine the Sony A1, but IMHO the first step toward becoming a true professional (which, BTW, I am not) is to learn to accept that modern phone cameras with multiple small lenses teaming together because the internal processing is what's teaming them together have come a very, very long way indeed. That plus the fact that I have taken better pictures with my old Nokia Lumia 625 phone than some people who like to call theirself experienced have done with gear that costs way up in the thousands. But I will admit I almost fell into the river Thames whilst taking a nighlty shot of Westminster Bridge two weeks before Christmas back in 2000 without using a tripod with the F80. The pic came out so great that they later decided to leave the EU as a result.

Hi there

While semi conductor technology has improved by unimaginable proportions physics is still physics and while the light capture techniques of small sensors can work at around 5,000 ISO you'll find that for large pictures the tiny sensor will have "interference" streaks because literally of movement of the electrons in the tiny sensor at typical ambient Room temperature.

Note for larger and larger resolution then the electrons / atoms are crammed together tighter and tighter and quantum physics means that as electrons "shift" in their orbits around the nucleus this causes interference and hthere being more electrons present in the material causes more interference. (That explanation is somewhat basic but one shold get the idea). Probably not important if pics are only ever displayed on the phone or on a smallish TV monitor - but even at A4 very noticeable. The reason NASA telescopes work is of course the much larger sensor size, the mega more expensive quality of it and of course operating at a temp not much above absolute zero where movement of electrons is almost about nil.

It's finally good to see though - at least on small compact zooms and some Pro DSLR's that there's an increasing amount of processing that's actually done in the firmware so not requiring any manual post processing correction. Camera shake and Red eye corrections are probably the ones most people will be familiar with.

I remember though going with a Car Ferry from England to Dublin - ROI and there was this guy on the ferry who'd set up his camera with a tripod and he couldn't understand while we were having good laugh. !!!!

Cheers everybody and good Thanksgiving -- and to UK colleagues I'd celebrate Thanksgiving too this year instead of XMAS if I were you as it looks like being Chaos central over there in December judging by what's in the worlds press. !!!!

Cheers

Christmas was cancelled years ago by the PC brigade (not personal computer). Aberdeen Council only refers to the Winter Festival but quite happily refers to Ramadan, Diwali etc.

There is photo thread in the Chillout Room. Could show results there.

Greatest photos

I was looking through some old photos and came across this one, taken on an old phone camera in a waterproof bag back when I was diving, I think about 2009 in the Red Sea, quality is poor but the experience at the time was far from poor. Right place, right time
