Lenses / Re: Help deciding on a macro lens
« on: August 04, 2014, 10:58:15 AM »
Sir, the Makro-Planar T 2.0 lens is one of the best and sharpest lenses, you can own. My youngest son, who works as an biologist uses this lens nearly each day on the Nikon 800E for off-laboratory shots. And the shots are really superb. You will find no better lens in image quality.

But: The lens (and the Camera) alone are no guarantee for superb pictures. As the posters before mentioned, there are a lot of other factors that influence the IQ.
My son uses an very expensive tripod, an Nikon multiflash system with (I think) 6 flashheads, an micro adjustment slider, and a lot more things to get the shots for their scientific magazines.

If you own this or similar equipment, the Zeiss lens will be the lens of your choice.

If you want to be more flexible the Canon 100L might be better for you.

Dear xps,

I recently bought the Lee filter foundation kit, 77 mm slim adapter, and a 67 mm regular adapter. I also bought two Hitech filters--a 2-stop ND grad and a 3-stop reverse grad filter. Finally, at the Calumet going out of business sale in New York City, I bought three Lee filters in various colors for $50. I wouldn't have normally bought the colored filters but at 75% off the regular price, I thought it would be fun to experiment with them.

Although the Hitech filters are 1.5 mm in comparison with the 2 mm Lee filters, the Hiech filters fit firmly into the Lee filter foundation kit and do not slip or slide around.

I am also very concerned about scratches on filters even though I am very careful with my gear. So I bought the following filter case:

http://www.bhphotovideo.com/bnh/controller/home/search?N=0&InitialSearch=yes&InitialSearch=yes&sts=ma&Top+Nav-Search&Ntt=Filter%20hive

I like it because the filter insert can be removed from the outer case, so essence you have two cases. It is a pretty well-designed case and you can wear it on a regular belt. I just recently received it and placed my filters into the filter case. I actually needed to remove the insert and put the foundation kit and adapters into the outer case due to the bulk. I am going to be taking everything with me to Hawaii next week and I will let you know how things go in terms of how well this case will protect my filters. The only thing I would've done differently if I would've designed this case would have been to use a different fabric for the filter insert. I am really hoping the fabric they chose for the filter insert case will not itself cause scratches to my filters. Again, after my two week trip, I can let you know.

At this point, my only other concern is to prevent the filters from breaking during transit. I'm not so concerned about how they'll be in my camera bag if I am hiking around, but whether they will survive the plane flight as bags can often get squished in overhead compartments in transit. Even if I put the filter cases in my rolling bag, there is still be issue of other stuff in the case mashing up against the filters. This may also be of concern to you for your mountain hikes. So I think I will find some sort of hard plastic case around the house that I can fit the filter insert case into.

Hope this helps,

Vivid

That would be fine!
I store my filters in an microfiber inlay, which normally is used to store sunglasses towers. (10 filters up to 11x16cm). The inlay is protected in an normal tupperware box with an lockable cover, that has the same size like the inlay. It can be easily stored in my backpacks

I was suffering from the same electronic problem, after I took some shots in the tropical greenhouse in the botanical gardens in munich. I dried the cam and put it in to my backpack, with some small drying bags (small bags often  added to prevent moisture). Condensating water (outside -10°C) corroded the electronic inside.
The back dial wheel, the info button, the menu button, and the right upper buttons did not work anymore.
 
It was not easy to convince the Canon Service partner that this issue is under guarantee. They just did it, because there were no water drops inside.
The technican there told me, that the 6Ds back is weakly water seald. In their experience just the 7D, 5D,1D are sufficently water sealed.
The funny thing is, that my old 60D never had any problem when I annually stayed inside the tropical greenhouse for hours.

Maybe, the Maerz GmbH in Berlin is quite as fair as the Service Center where I sent my Cam.

Thank you for your postings.
The problem with scratches are an issue to me, as I climb around in the alps and Dolomites. So, as I´ve been told, the LEE products would be a little bit more "resistant".

I will fetch the Foundation Kit with the 58mm and 77 slim adapter and the set of 3 soft ND graduation filters. Maybe followed by an hard .6 ND and 1-2 coloured filters. What are "reverse filters"?

Does anybody use the Adaptor to mount an 105mm polarizer in front of te lee filterholder?
Does it work well, or is the IQ much worser than without the filters?[/i]

I will buy an Heliopan 105mm polarizer, as it is much cheaper and the factory is near Munich. The quality of the Heliopan Filters are quite good, I own a lot of them.

I want to buy an graduated filter kit for landscape photographing.

As Lee is very expensive, I am looking for cheaper, but still good graduated filters. Size 100x150mm

I found the company "Hitech".
Does anybody own this gratuated ND filters? Which quality to buy as there are some different types available?

I would suggest to buy 3 soft and 3 hard ND filters, and maybe 1 or 2 coloured filters (tabacco...)

Is this an good decision, or does anybody know another good product?

When I did a flight over the dunes in Namibia, I shot mostly with the 24-70 but that was based on the landscape. I was lucky to have a second body and had a 70-300 but that's a lot more difficult to get good shots based on speed of flight, jerkiness of ride etc.

For a couple of helicopter flights (Vic falls and rockies in Canada), I used the 16-35 and 70-200 (single body), so I swapped lenses during the flight...

It does depend on your style of photography, but if I could only have 1 lens it out of your list it would be the 24-70.

Few other tips

  • Be sure to use Tv or auto-iso, as you need to have approx. 1/1000th of a second speed to ensure you don't blur the shots (of course this depends on what direction you are shooting in relative to the plane).
  • As mentioned - windows cleanliness and reflection, again of course watching out for the sun as well (glare).
  • Check out the plane before and decide the best seating position - normally at the back or at the front, otherwise you will get the wings in a lot of shots
  • Scout out the location before and see if there are particular areas - maybe even use google maps to give you the birds-eye view for planning if you can influence the pilot.

+1

  • If you can get some influence, ask the pilot to fly an turn, lowering the wing on the side where you want to shoot
  • Take care of smoke/hot air that is released from the engine, if it is an single engine or an plane, where the exhaust passes your photo motives
  • Sometimes it helps to mount an flexible (rubber) lens hood (take care of vignetting), that cou can press against the canopy
  • If possible, try quickly all three lenses when you seat in the plane - so you can imagine the visual field
  • Take care of in which direction you shoot, if the sun is in your shooting direction, in canopy reflections can appear
  • Best shots in the evening, when the sun is in an low position. Super effets from long shadows and warm light
  • Carry some cleaning wipes for the canopy

Found @ dpreview.

Maybe this invention will improve IQ in the edge regions of our Sony pictures

Software & Accessories / Tablet to use as remonte for 6D
« on: June 22, 2014, 12:34:06 PM »
I am looking for an (non Apple) >= full HD tablet, sized 10" plus with an high brightness.
I will try to use the tablet as an remote for my 6D (macro, try to begin portrait photography).
Connection over Wifi only, no LTE e.g. is needed.

Do you know an good product for this?

Sorry, for beeing not precise. I shot on approaching racing cars, high speed AF and continuous shooting. The cars had about the same speed each pass. Afterwards counted how many pictures were sharp.
Ok, I will ask my friends, if I can do AFMA on their leneses at CPS.
Thanks for your information

All lenses were adjusted by Canon CPS in spring this year. But only on their "home" cameras.
Ok, the sharpness will be influenced by that, but does AFMA influence the AF performance too?
Same situation, my lens got about 60% sharp, the worst of the three just about thirty? But why?


59
I recognized that my 70D´s AF performance and accuracy varies from lens to lens.
The German "Color Foto" magazine compared the AF perfomrance and accuracy between some Cams (SLR, MLils,...) and between some lenses. There the 70D was no winner.... It perfomred best with the Sigma 18-35, worst with the 50mm Macro... (Lesser than half of all shots were sharp. NEX-7´s shots were over 90% sharp...
Ok. I read the test and was a little bit disappointed. I see thath some lenses perform better, some worser on the 70D. Noteable: mirorless Cams are most superior to the SLR (in this price class)

My question: I´d like to know, why my 70D´s AF performance varies so much, using 3 different 70-200 2.8L lenses when I shoot moving objects? I rented 2 from my clubfriends, one I own by myself. Mine was fast and mostly sharp, one was better (more sharp pictures), one noteably worser. But why?
