algrove Posted May 1, 2015 Share #21 Posted May 1, 2015 Advertisement (gone after registration) OP If you are very seriously concerned about lens changes, pick your 2 favorite lenses for the day and put each on a different body and no lens changes are required until back in the hotel. Otherwise follow the above advice. Link to post Share on other sites More sharing options...

jdlaing Posted May 1, 2015 Share #22 Posted May 1, 2015 Change them only in a clean room. Link to post Share on other sites More sharing options...
wda Posted May 1, 2015 Share #23 Posted May 1, 2015 A good question and some good answers. One more suggestion. Consider buying a good 28-35-50 Tri-Elmar. I know they are hard to find which proves just how much owners value them. But they come into their own when travelling in dusty conditions. Admittedly you are limited to three focal lengths; but for many travellers they are very popular focal lengths. Link to post Share on other sites More sharing options...
stephengv Posted May 1, 2015 Author Share #24 Posted May 1, 2015 Thank you for the replies. I just bought a sensor swab. Also, I'm looking at a ziplock bag to protect my lens changing. Link to post Share on other sites More sharing options...
dpitt Posted May 2, 2015 Share #25 Posted May 2, 2015 I like to have two bodies with a choice of lenses. Before I go out I put the lenses of choice on and avoid changing lenses outdoors. I once shot several hundred holiday pictures with one large fiber in the middel of the frame! Because I did not have a laptop with me on that holiday, I did not notice it until I got home and loaded them on the computer. Almost all keepers needed heavy photoshopping. So, when possible, check your sensor after switching lenses outdoor. (at least once a day) You could do that by putting the lens on smallest aperture, then move the camera while taking a picture of the sky or a wall. Then magnify the preview and scroll through, Also if you have to do it outside, turn your back to the wind and hold the camera in front of you facing down. Changed a lens once near the sea with the wind blowing in my face. I will never make that mistake again. Link to post Share on other sites More sharing options...

I find the following method even better. Simply select Menu>Sensor Cleaning>Dust Detection and shoot a sheet of well-lit white paper inside (or the sky) by following the instructions given on screen.

Exodies Posted May 3, 2015 Share #27 Posted May 3, 2015 Advertisement (gone after registration) Dust moves under the influence of air currents, not gravity. Unless you are standing in a down draught then holding the camera face down is pointless. Link to post Share on other sites More sharing options...
erl Posted May 3, 2015 Share #28 Posted May 3, 2015 Dust can also collect inside change bags! Whatever you do, you are living 'dangerously'. At least you are living, if you are making pictures. Link to post Share on other sites More sharing options...
jmahto Posted May 3, 2015 Share #29 Posted May 3, 2015 Only time I am really careful about dust is when I am planning to shoot video. In that case I do inspect and clean any big dust spots on the sensor in advance. It is impossible to clean dust spots in video. Link to post Share on other sites More sharing options...
jaapv Posted May 3, 2015 Share #30 Posted May 3, 2015 Dust moves under the influence of air currents, not gravity. Unless you are standing in a down draught then holding the camera face down is pointless. How does it settle on surfaces then? Link to post Share on other sites More sharing options...
erl Posted May 3, 2015 Share #31 Posted May 3, 2015 Of course gravity is a component but possibly a smaller one than air currents, hence some settles on vertical surfaces too. Relativity of risk rather than elimination maybe? Also, air currents may carry dust away as well as deposit it. OTOH, they will not clean it out of bags so readily.

Peter H Posted May 3, 2015 Share #32 Posted May 3, 2015 Personally, I thinking using a bag to change lenses in is taking things just a bit too far. Worry less, enjoy more. Link to post Share on other sites More sharing options...
tobey bilek Posted May 3, 2015 Share #33 Posted May 3, 2015 Best cleaner I found is lens pen and scope. You can see it removed in real time. No chemicals. Naturally prevention is better than cure, but stuff happens. Link to post Share on other sites More sharing options...

jaapv Posted May 3, 2015 Share #35 Posted May 3, 2015 That does nort explain that it settles more on the top of things. I still support gravity. Link to post Share on other sites More sharing options...
Guest Posted May 3, 2015 Share #36 Posted May 3, 2015 Thanks for another injection of Antipodean common sense. Or use a zoom and a DSLR, both weather-sealed. Like most photogs and all pros. Them not having time for forA (regardless if knowing that it's not forUMS and that Antipodean is Greek). They have to deliver - no time to chat.

Peter Kilmister Posted May 3, 2015 Share #37 Posted May 3, 2015 When the London to Brighton car run took place last year (held annually to commemorate the end of having to have someone walking in front of the car with a red flag) it was held in a downpour. All those with DSLRs had to take off their coats to protect their DSLRs. The camera owners were soaked. M 240a are showerproof and could have been used provided the hot shoe cover was in place.

david strachan Posted May 3, 2015 Share #38 Posted May 3, 2015 Dust can settle electrostatically. It can be pollens full of sticky oily junk. As time goes on the sensor on my M8's becomes easier to clean....or I don't worry so much... I change lenses 3 times a day, and clean my sensor every 4-5 months. Used to advocate vacuuming, but now blower, SensorKlear by lenspen, swabs and isopropanol. cheers Dave S Link to post Share on other sites More sharing options...

Yes...was suggesting using freezer, or clear shopping bags, in hostile environments. cheers Dave S Link to post Share on other sites More sharing options...
Peter Kilmister Posted May 3, 2015 Share #40 Posted May 3, 2015 Dave, I really like your idea of big freezer bags. Cheap, easy to keep clear of dust, pollen, etc. Also easy to see what is going on ... which for some people is a must. Great recommendation and one I shall use. Thank you.
