Lenses / Re: EF 50 1.8 STM
« on: March 02, 2015, 04:35:39 PM »

Some of the best 50mm lenses ever made have been f/2.0 —


So true. The favourite 50mm lens of my career is the Nikkor 50mm f/2. It was sold as a 'budget' alternative to the f/1.8 and ( in those days ) very expensive f/1.4.

Well like you do, I thought the four times more expensive f/1.4 Nikkor must be better, so I saved up for one. For years I was completely baffled as to why it wasn't as good as the f/2 lens ! Fortunately I hadn't traded the f/2 one in. I ended up trading the faster lens for something else.

So if we got an f/2 50mm STM lens that was as good at f/2 as the 40 pancake is at f/2.8 I'd be in there.

Well all this talk of a possible new 50mm lens of f/1.8 to f/2 got me thinking about one of my few Nikkor lenses that I have left; the 50mm f/2 Ai-s.

As I said in the quote above, I remember this lens as being the best 50 I ever used. I remember spending ages puzzling over why my nice new, shiny and expensive Nikkor f/1.4 wasn't as good.

So true to my word I bought a Nikon : EOS adapter and gave it a go, having first had to cut the rear peg off before it took the mirror out of my camera.  Well I wasn't looking back at the past with rose tinted glasses, this lens is superb from f/2.8 onwards, easily matching the potential resolution of the 5DII sensor. It is slightly sharper than the Canon 1.4 lens at these apertures, but much more so to the edge of the frame. At f/2 it is 'dreamy', but in a very attractive way, and I think the bokeh is quite interesting.

When making a lens that is really stellar at mid apertures it is much easier to achieve this with a lens that is slower to start with. This Nikkor f/2 and other lenses such as the 40mm pancake are examples of this. So if Canon were to produce a new 50mm f/2 lens it could well be stunning for a very reasonable price. I'm really hoping that we get a 2015 version of this Nikkor f/2. IS as well if they can keep it this good.

I've attached two pictures. The first is at f/2 + a little fill, softened with tissue, though of course this lens doesn't give any information to the flash, so accurate fill was a little erratic. I like what the lens has done here.

The second is a hand held snap at f5.6 and this picture gives an idea of the contrast the lens help to give. This is pretty well straight off the camera, tweaked in levels and the only sharpening is USM : 100% @ 0.4 pixel. The third picture is a 100% crop.

The only time I have used this lens on FF digital before was when I tried the Nikon D800. I now realise that one of the pluses of that camera wasn't actually the camera at all !

So the moral of the story is if you want a reasonably priced lens that is razor sharp after one or two stops in don't make it too fast in the first place.

Very nice, I mean the family.  Sure, the photos, too

Thanks Lion Rock. Just realised that there aren't really any showing the baby; I don't want to be accused of photographing everything but the baby, so here is one of the baby doing what babies do.

5DII, ISO 160, 1/2500 sec, f2, filled with high speed sync and a tissue taped over the flash.

Congratulations!!

Many thanks SPL. Great to be able to hand a baby back !

Here's some of the latest additions to the album:

The first two are the EF 50 f/1.4 @ f1.8

The last two were shot with my very old Nikkor f/2 via an adapter @ f2 I remember this lens as being the best 50 I'd ever used, and when actually using it again thought maybe I was remembering it through rose tinted glasses.

It is soft at f2, with a fair bit of veiling and coma, but at f4 to 5.6 it is stunning, right across the frame. Easily out-resolves the 5DII sensor, with better contrast too, but that's the topic for a different thread.

EOS Bodies / Re: The State of the Camera Industry in 2014

This is quite interesting. The decline in DSLR-sales is tremendous. Does anyone have data from pre-digital age wich compare for instance SLR-sales vs. simple cameras like the Kodak instamatic?  What is about the increase of the amount of digital pictures, i have in the mind that it must be huge. How many smartphones with cameras are sold? And is it not so that many people are making videos instead of pictures? (you-tube growth!)

In the sum DSLRs perhaps are devices wich are dying in the forseeable future, especially the expensive ones, or is there any reason why it should be not so?

Greetings Andy

Don't ask me to chase around for hard figures, but as the film slr developed into the dslr, and this tech began to cheapen and mature the ownership in 'higher end cameras' ( ie interchangeable lens cameras) exploded, and many more people partook in this type of photography as a hobby than they ever did with film. This sort of growth is unsustainable in anything, and the used market is awash with perfectly contempory dslr cameras for very little money, the rise of Internet sale sites such as ebay have added to this.

So what we are seeing in sales is to be expected, the 'mirrorles' vs 'dslr' is only a tiny part of it.

Canon General / Re: RIP Leonard Nimoy

Leonard did "Live Long and Prosper" but no one lives forever except, perhaps, in our memories.
He will be remembered long after we have gone - RIP to a man who has touched all out lives.

That's the great thing about being an iconic actor: Nemoy will in fact be alive and kicking as Spock for generations to come.

Enjoy Star Trek as much now as I ever did.

Dale Photographic in Leeds are saying May, and they normally get the new gear in quite early.

AFAIU, mRAW and sRAW only use the central portion of the sensor, but the same pixels (no binning).

And you're concerned with lens optics and pixels being muddled ?

I just ordered the Canon EF 100 F2.0. Finally I'm going to have a new toy to play with :-)

I agree with you on the Nikkor f/2; it's the best 50 I've ever used, or at least I remember it that way. I've never used it on a FF Canon but your posts have inspired me to get a F to EF adaptor and get my old Nikkor 50 f/2 into digital action. Unfortunately the focus ring on mine is now quite loose but maybe I could have it serviced and re greased.

Funnily enough this lens is almost a pancake design, set into a conventional 50mm f1.4 barrel.

Given that you have an adapter I'm surprised that you haven't got hold of a Nikkor 105 f2.5. This was / is a superb portrait lens, and had a stellar reputation in its day.

My backyard a couple days ago.  Canon 5d mkii pano with 200mm f/2.8 ii

IMG_2928-Edit by Andy Hodapp, on Flickr

It's a great lens for panos; I'm a fan of the 200mm f/2.8 - it's not too heavy, not too expensive but is a first rate optic. Because of the aperture generally required for landscape IS wouldn't be that much of a help anyway, at least not at low ISO, so I like it as is.

EOS Bodies - For Video / Re: A Suggestion on the EOS-1D C Replacement
« on: February 24, 2015, 04:45:42 AM »
Clearly all this talk of the 5Dc on internet forums has given Canon the idea.

This could be where the modular design that we have hear about comes in: the real 5Dc will have an interchangeable viewfinder, one a traditional prism and works with the mirror as normal, just like a Canon F-1, Nikon F3 etc, and another viewfinder that is an EVF, primarily for video. Mirror automatically locks up when the 'finder is fitted, and away you go. AvTvM will love it.

If Canon don't do this I think they will really have missed a trick, but maybe they have forgotten that some of their SLR design from years ago had an interchangeable viewfinder.

I'm not surprised about the 1Dc. I've seen loads of 5DII / III's being used for professional video at all different types of functions; I've never once seen a 1Dc.

'scan the trannies' - not sure you can say things like that anymore  ;D ;D ;D ;D

I never was politically correct   :D

Some great artists are financially successful. Most are not. Some great artists are very popular. Most are not.

At least not until they are dead  ;)

Get a 5D.

I notice that in the UK prices of good, used late production 5Ds ( no, not the 5Ds, the plural of the original 5D) are actually beginning to go up.

I don't think 'T' stops fully explain what is happening. For instance the 24-105L has a T stop of 5.1 ( as opposed to f/4) and the 24-70 L IS has a T stop of 4, yet both these lenses will under expose by about one to two thirds of a stop compared with fairly simple primes such as the 50 /1.4 and the 85/1.8 for the same exposure setting.
