Generally speaking, those puppies are assembled so no ordinary man can find his way in. Your best bet is to send it into Sigma, or drop it by a camera store, or put up a post on craigslist.org - You'll be better off in the long run knowing that there will be no damage to your internal elements. A single mishap can mean goodbye beautiful prime - the elements are coated with certain substances that are crucial in the lens's disbursement of light - removal of these coatings is a baaaad idea.

How to clean sigma 500mm 4.5 fungus


Do you have a lens collimator and other gear needed to ensure proper alignment when reassembling the lens? If not, try this. Put the lens inside a window where it receives directly sunlight. Yes, you'll probably have to move the lens every few hours to it continues to receive direct sunlight. Do this for a day or two. If the fungus persists then take the lens to a reputable camera shop and have a properly trained and equipped professional clean the lens.

Is the Sigma Telephoto 400mm f/5.6 APO AF lens compatible with the Sony alpha camera?


Sigma makes their lenses with a variety of mounts. A lens with a Canon mount, for example, will not fit onto a Sony camera. Assuming you get the Sigma lens with a Sony mount then yes, it will be compatible with the Sony alpha.

Hi, It appears there is a small amount of fungus inside my lens, and when taking a picture, it comes back very dark. What would a possible remedy be for this? Many thanks Jon


This is actually a very common situation for older lenses. You should take the lens to a trained technician and have them clean the inner elements of the lens. Often times they can, if the fungus isn't too bad. In extreme situations, they will need to replace the element itself.

135-400mm lens on nikon d40


Unfortunately, this lens is not supported by the D40 due to Nikon's unfortunate decision to leave out the autofocus motor from this camera.  This is why I tell folks not to waste their money on the D40 - access to the many, many, many lenses that Nikon has made over the years, many of which are available used for a substantial savings, is lost on this camera.  The only Nikon lenses that work are AF-S lenses, and some third party lenses that have their own internal motors.  I got a list of Sigma lenses that are compatible with the D40 for you:
The list of compatible Sigma lenses for the Nikon D40 as of the current date is as follows:
  • 10-20mm F4-5.6 EX DC
  • 12-24mm F4.5-5.6
  • 17-35mm F2.8-4 DG
  • 50-500mm F4-6.3 DG
  • APO 50-150mm F2.8 EX DC HSM
  • 70-200mm F2.8 DG MACRO
  • 80-400mm F4.5-5.6
  • 100-300mm F4 DG
  • 120-300mm F2.8 DG
  • 300-800mm F5.6 DG
  • 14mm F2.8 EX
  • 30mm F1.4 EX DC HSM
  • 150mm F2.8 EX DG
  • 180mm F3.5 EX DG
  • 300mm EX DG
  • 500mm EX DG
  • 800mm f5.6 EX DG
from here:  http://www.imaging-resource.com/NEWS/1177682545.html
Sorry for the bad news.  The cheaper thing at this point may be to sell the D40 and get a D80.  I personally have a D70S, but that is no longer made.

I need to know the value and info on this lense


There are two versions of this lens.  The Telemacro version takes 77mm filters and is quite good.  It sells for $325-400 depending upon condition.  The other version "APO" is not very sharp and has low contrast.  It takes a 72mm filter and usually sells for approx. $125-$200.  I would not recommend this one for any serious photographer.  The Telemacro version is a nice affordable 400mm lens with decent performance.  Both lenses have slow AF, but the fast focusing alternatives are hundreds to thousands more.
