lensses fro the 1.5 factor please!!!

With so many new nikon mount DSLRs on the market and hatchlings, there is as yet not even one lenss made for the 1.5, or 1.7 factor that the cameras --exept the Contax-- all have. The lensses could be much smaller, and faster if made to fit ONLY the image circle of this cameras. They shoul also make cameras 1.5 times smaller, but that is another story.

Guess what. Within one, two or three years you can buy a full image CCD. Than you have to sell all your little lenses, because they don't cover the more big CCD. Better to get a lens that you can use within the future too.

I have lensses that can do 1.0x but I want only one that would be as having my 20mm for -say, the s2-. Also i am concerned about what Olympus said in my E-10 manual that the made a new lenss not only to fit the smaller sizes to be exposed, but also because the way that light has to reach the film plane in order to transfer the info. to the pixels.

I dont see why they dont make this lensses available and let us deside to buy or not. After all some of us are spending 5k in cameras that are obsolete in 6months...

Still it is not interesting to make lenses specially for little CCD chips within digital SLR camera's only. The market segment still is to small to make lenses exclusively to this smaller CCD size. In that case, brands shall sell less lenses, because users with a normal 35 mm lens shall not buy it. Less selling lenses, the costs of developement of such a lens shall be spread to a smaller amount, so the lens shall cost more. Who is willing to pay more for a lens with less usage (you can not use with your 35 mm SLR)?

And as you say digital camera are obsolete in 6months. Do you know wich camera you are planning to buy afterwards? If it has a more big CCD, your "little" lens is worthless, specially when you want to sell second hand, because no normal 35 mm user shall buy it, nor new users which have a digital camera with a more big CCD.

If I want to buy lenses for my camera (Nikon D1X), I only do want lenses that I still can use when I am planning to buy a digital camera with a more big CCD, and that I still can use to my other normal 35 mm film Nikon SLR.--Leon Obers

Frank,

I am a Nikon format photographer from way back. The majority of my work is sport and outdoors. I, for one, appreciate the extra distance obtained from my standard lens kit.

I don't do a lot of wide (or extemely wide) angle imagery. The purchase, for me, of a wider angle lens than I already had is less of a financial burden than they burying lenses at the other end; 600mm+.

I am now very familiar with this setup and would prefer that the CCD size remained as is but the pixel density continued to increase.

Regards, Darren

As has been explained before, the CCD's or CMOS sensors require that light hit them at the proper angle. The lenses cannot be smaller because if you made them smaller, light at the edge of the lens would not hit the sensor properly.

And if you look at the Contax (which by the way has been delayed), you'll see that the lens is HUGE. This is because it uses a "full-frame" sensor and so, the lenses have to be correspondingly bigger. I read somewhere that it actually uses medium format lenses.

BTW, if they made the cameras 1.5x smaller, well, they'd be too small to hold or manipulate.

The lenss of the E-20 Oly was designed to serv the new media and I think that eventualy all lensses are going to forget the times when they were made for film. It is only matter of time.

The 1.5 factor is a good thing, but the fact that I can't do decent architectural work is not good for me and many other wide angler photographers like me. I think that when we are all happy with the expansion of the megapixel gold rush the consumer and manufactures are going to realize that the emperor has no wide angles.

I have a complete RZII 67 set, but there is no reazon any more for such a massive negative size when virtual film is geting even smaller than 35mm,--1.7factor-- This represent a big problem for me because I also want to be able to use my SINAR with all the movements --forget about my 65mm schnaider for 45 interiors-- but it is ridiculous with a "plate" smaler than a slide....

They are going to redesign everithing from the lensses to the cameras. It is like retrofiting the jet engine to proper planes what they are doing now. Jet motors are smaller and we dont need to "make them the size of all engines so that the fit in our inventory of IIWW planes and so we can save in new bodies".

Is anyone out there that sees what I am chatting about??--Frank Barret

Yes, only do use the right digital tools.
--Leon Obers

Frank: I fully support your view of the undesirable "magnification factors" and the huge problem it creates. I thing an OM type digital would be wonderful. When lenses weigh from 2 to 4 pounds to just cover what we want 28-200 to be, that is a problem for me. More glass =more expenive. Somebody has already mounted a posterior lens element to straighten the light before it goes to the sensor, so that is not the real problem, either. I'm not sure which company does this but they surely make a big deal of how inventive thery are with it. I say let's foget the film requirements and fit the camera to the sensors.

This is a cc from the Nikon forum about the 1.5x problem...I

"Nikon should build a couple of wide-angle lens just for the D1 series cameras, with the 1.5x conversion factor taken into consideration. I mean, to get a 20mm equivalence of a 35mm film camera, I have to buy a 14mm Nikkor lens at $1200? That is outragous.
I do not need to extra wide "view" of the lens, just the middle portion.

They can call it the "D15" lenses, or "Z" lenses, to be used on D1, D1x, D1h, and coming soon D100 only.

There should be a Nikkor 14mm AF-Z lens that cost about $400 (which is high considering the 20mm AF-D is only $250), and 10mm AF-Z "normal" fisheye. And maybe a super-wide 8mm AF-Z wide-angle at $1500.

If Nikon don't want to do it, maybe Sigma or somebody would, that is call competition. The glass quality should be same as Nikon.

More and more people are buying Nikon DSLR, and it does not look like Nikon is going to deviate from the 1.5 conversion factor.
What say you? "
--Frank Barret

I have been leaving several notes about wishful thinking of digital photographers about affordable (less than $1000) full frame Digital SLR in the near future. Please read my threads if interested. I tend to disagree with Leon: I think Canon and Nikon made it clear with the introduction of d60 and d100 that there is no hope for an affordable full frame digital SLR for a long time: ZERO procent improvement in focal point multiplier over almost 2 years!!!!!!!!!!!!!! There are (contax N) and there will be full frame SLR's for fanatic professionals with loads of 35mm lenses for a premium of $7000-$9000.

The reason is the high price of semiconductor wafers which is relatively stable (I say gold doesnt get cheaper). The highest pricedrop of the raw material was 10% in 1998!! And there are years when it went up. But if you calculate with an (unbelievable) annual pricedrop of 10% then in 2010 the sensors would cost $4000 unless something drastic happens with the yield (even if the yield doubles it is $2000). So what Nikon, Canon and Sigma are doing is this: instead of developing new digital size lenses for these 20-23mm sensors they decided to make horribly expensice super-wide-angle lenses! Does it sound like they want to make extra profit? Yes! Does it sound like lack of innovation and intention to invest? Yes! And in the meantime they make a few hundred full-frame SLR to make naive people dream about them and buy their old-fashioned lenses!!

But I think Sony will do it soon.

That is only a very short time.
Some of my lenses are over 15 years old, very good to use to my D1X.--Leon Obers

How do you know they don't want to deviate from the 1.5 conversion factor? Only because within three years they used this conversion factor?
What about the next successor from the D1X?

OK I doubt it shall be full frame 35 mm, but perhaps maybe 1.3 conversion factor.

Lenses I do keep for long time. I do use lenses that I use already for 15 years. No reason to sell them, they are great. I can still use it at my normal film SLR and yes also to new digital SLR in future (I hope).--Leon Obers

D1x is just the tip of the iceberg. We should not see the future through that.
--Best wishes,Zoli

If it was true my coolpix 5000 would not function. Probably none of the coolpix cameras (or the likes) would.The contax will (if ever) use 35mm lenses. The lens look big on the photos only because it is a wide angle zoom lens.

I bought a Sigma 15-30mm EX DG for my S1 in the knowledge that it was designed as a wide angle zoom for digital SLRs.

Sigma make at least five lenses that are targetted towards digital SLRs.

From the FAQ on Sigma's web site:

Sigma presently offers a number of lenses designed specifically for digital SLR cameras, which can also be used with 35mm SLRs. They are mostly wideangle and widezoom type lenses with large apertures (e.g. 20mm f/1.8, 24mm f/1.8, 28mm f/1.8, 24-70mm f/2.8, 15-30mm f/3.5-4.5), and feature superior light distribution, so that there is minimal light fall-off or vignetting, even when used at maximum aperture. These lenses are designated DG type, and are part of Sigma's EX series of lenses. Remember that the digital imaging device is generally much smaller than a 35mm negative, so the lens will have a longer "effective" focal length. The conversion factor is generally about 1.5X, so a 14mm lens effectively becomes about 21mm when used on these digital cameras. As a result, there are few choices available for wideangle lenses, or even fast "normal" lenses, for these digital cameras. These new DG lenses help fill this void.

Steve Short

Here's where someone explained about the limitations of lenses; in the post, the writer mentions that the Contax uses medium format lenses.

I checked contax's website and the site says the Contax uses their standard 35mm lenses. Now I don't know what to think.
