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..

Hi,

i am looking for a light sensitive lens to go with my D70s. The 50 mm 1,4f mounted on a digital camera is affectively about 70 or 80 mm and thats a bit too much tele for what i need.

can anyone recommend the nikkor AF 28mm, 1,4D? does ot go well with a digital camera?

does anyone have experience with other good normal or wide angle lenses? the above mentioned lens is the only good one i can find...

thank you in advance!!

/Fred

Fairuz -

I assume you mean digital SLRs. The main thing is that the sensor in most digital SLRs is smaller than a frame of 35mm film, which causes the lens to have a different field of view with the same lens. A smaller part of the image circle is recorded. This has the apparent effect of increasing the focal length, but is really just a "crop." There are conversion factors in various D-SLRs out there of 1.3, 1.5, 1.6 and 2.0, probably more. The specs of every camera tell you what it is. There are also (very few) full frame digital cameras. These retain exactly the same attributes of a lens mounted on a 35mm film camera.

The classic problem is that small sensor DSLRs need extra wide lenses to achieve the wide angle coverage we're used to. On the other hand they cause medium telephotos to "act like" longer ones, which is an advantaged, opposed to losing the wide angle coverage. Many manufacturers are now making lenses designed to work with the smaller sensors, (mostly zooms) and which are incompatable with full frame DSLRs or 35mm film cameras. For example Canon calls those lenses "EF-S" They're optimized for the sensor size, and many of them are "ultra wide' focal lengths like 10, 12 and 16mm at the short end of the zoom range. After applying the sensor conversion factor, their FOV is quite abit narrower.

There are other considerations, like pixel size and pixel density, which can weigh the advantages one way or the other.

Hope that helps, there's tons more reading you can do.

Now if you meant the lenses in compact P&S cameras - I have no idea! :-)

The lens will physically mount to the F5's lens mount, but you will need to ensure that the meter coupling lever is moved out of the way prior to mounting. This should be covered in your camera manual. However, the lens will not meter through the camera's metering system automatically, and you will have to use stop-down metering.

I have a Nikon Nikkor-Q Auto 1:2.8 f=135mm serial#: 271495 (1974 I think)

My question is can I mount this to an F5 ?
I think I read somewhere that there is a required kit for this lens to utilize it on F-Mount cameras such as the F5. Anybody have further info?
Thanks in advance.

Ops man -

With any manufacturer, the determining factor for sharpness is the lens. I suggest you first determine what focal length(s) lenses you will want, find out what Nikon lenses are available in that range, what you can afford (always buy the best you can afford) and then start Googling reviews on those lenses. Or go to PhotoSIG.com and do a search on a particular lens and look at samples. Nikon, like Canon, Minolta, Pentax and others makes overall excellent lenses, but there is a range. Fundamentally you get what you pay for. Inexpensive consumer grade kit lenses are not going to give you the absolute sharpest results, like a $1200 lens will. Howrver, modern lens technology has grown to the point that yuou can get quite acceptable results from very affordable lenses, especially to your beginner's eye. I had been photographing a long time before I started to be able to discern certain kinds of critical sharpness. Now of course, I can't go back! Enjoy the learning process, how and what you photograph is in the end much more important than your equipment.

Hello all.

I own a Nikon D70s, with a 18-70 DX lens, a 50mm AF lens, and a Tamron 70-300 AF lens.

Now I am looking for a full manual analogue SLR, to replace my aperture-only Canon AV1. I was thinking of getting a Nikon, because of the possibility of all my lenses still working (as oppose to EOS/FD by Canon)
Am I wrong? Will my 'modern' lenses (with the exception of the DX lens) work with, say an FM2n, or a FM3a? Because I can possibly buy an FM3 body for cheap.

Kind regards, Thomas
