Sometimes we all become too interested in the camera body because that is where most of the gadgets are. But it is the lens that makes the picture and most often the lens has a more direct influence on the eventual image quality 'output'. If economy is a consideration, you should consider buy a less expensive camera body rather than less expensive lenses. If you buy a SLR camera with only one lens is also not logical because you might as well buy a cheaper camera with a fixed, non-interchangeable lens like a P&S. But modern lenses has such fantastic features such as high power zoom with previously unimaginable zoom range which actually makes a single-lens-do-all photographic system viable. All those messages posted on the variuos Message Boards for SLR Models are not short of interesting comment and remarks on lenses. Well, not to confuse others who are just interested in cameras, I thought there is a neccessity for a separate Message Board for those who are interested in discussion on various issues on lenses as well..

To Dave: Begining with the F90, followed by F50, F90X, F70, F5, F60 and finally F100 these cameras use the distance information provided by the D-lenses built in electronics in computing exposure when metering is set to matrix mode. Nikon calls it 3D matrix metering; it is only available with the D lenses in combination with the above mentioned camera models. The earlier non-D lenses works just as well with the above cameras except that you only get matrix and not 3D matrix metering. The effect of computing the distance into the exposure is said to be most visible during flash photography, in combination with Nikon's dedicated flash.

Since the mid 70s, I've had the pleasure of owning a Nikkor 135 mm 3.5 lens. Recently, I've noticed some type of growth on the inside of the glass. I've seen comments on fungus in used lens ads. Is this my problem? If so, how can it be resolved? Thanks, Ken.......

I'm wondering what the difference between Nikkor D-type and non-D-type AF lenses are, and their compatiblity with a new N70. I have a 35-70 AF that I think is non-D, and I'm wondering if all the functions on a new N70 will work with it. It works great on my FE in manual mode!

To Ricky Thank you for your very informative reply on the use of 3rd party lenses for Canon EOS cameras. Sometimes one is tempted to buy 3rd party lenses because the price differential is so great. For example the Canon 17 - 35 mm is 2 1/2 times that of the Sigma 17-35 mm.

TO PATRICK: Of course an original Canon EF zoom lens is better than any independent maker's version. There are three for you to choose from, the EF 17-35mm f/2.8L USM, EF 20-35mm f/2.8L AFD (discontinued) and the EF 20-35mm f/3.5-4.5 USM. The third one is the most affordable while the discontinued one can be bought at a good price from most reputable second-hand dealers. The 17-35mm is expensive, used or new. There are also severe mismatch when using an independent maker's lens with EOS cameras. While such makers may have licensed the EOS technologies from Canon for their lenses, they do not possessed the precision required to operate with most EOS models, especially the latest versions like the EOS 88, EOS 300 and EOS-3. One of the weaknesses of independent make lenses are insufficient or overloaded power voltage when used with these three cameras. A new battery may last less than a week or prolonged usage with such lenses may cause these cameras to automatically locked-up whenever they detected unfamilar power surges or malfunction altogether. I am not kidding on this one. I have used the Tamron 28-200mm zoom lens on my EOS 100 with no problem but it nearly fried my new EOS 300. I don't have any high battery consumption problem when I used my EF 20mm f/2.8 USM lens with the EOS 300. And yes, independent makers' lenses have slower AF response, are noisy and not as reliable as Canon's. This is understood. You get what you pay for.

I owned a Canon EOS 50 and a EOS 100. I am interested in acquiring a Cosina AF 19-35 mm f/3.5 - 4.5 just to get a feel of wide angle lenses. Have anyone of you out there with any experience with this camera-lens combination. Will it perform well,will there be any technical mismatch between the lens and the camera, will it hunts badly, it is noisy and will it function well only when new and after a while, it will just give you trouble. It is worthwile buying it at all or should I go for the original Canon lenses. Your views would be much appreciated.

ohn, the lens you have is a Nikkor and not a Series E. They just did away with the rabbit ears that's all! I have a similar on with serial no. 442xxxx that is excellent and a bargain for the S$100 that I paid for it. Mine has "Made in Japan" stamped on it although I believe later samples were produced in China.

##### Hi Olympuses ##### Not forgetting the Olympus 24f3.5 shift lens, the widest shift lens for 35mm SLR cameras. Olympus is well remembered for their macro system, probably the most extensive in the market.------------------------------------------------------------------------
