Third Party Manufacturers / Re: Pentax working on FF DSLR
« on: February 05, 2015, 05:15:08 AM »
At long last; an alternative in the FF market to continually cheapening Nikons and ergonomically disastrous Sonys.

It will never be intended to match the Canikon sports cameras; it will be quirky but it will be good.

62
When the D800 came out I tried it because I was interested to compare a 36 mp single frame with 3 vertical frame stitch from the 12.7 mp 5D, which worked out at about 28 mp, and the same thing on the 5DII which was about 55 mp. Even the 5D stitch was far superior to the 36 mp single frame because the original image was over twice as big.

The reality is that if you are looking for more quality, resolution, enlargement etc than the mid twenties FF size sensor can give you really need to go to a larger format.

I'm sure there will be a lot of people who buy a 5Ds or sR who would have been better served by a 5DIII / IV.

It may be that in the short term, before the release of the 5DIV this high mp camera may offer some IQ improvements, but I can't see it lasting over cameras with larger pixels.,

63
I will be getting a 1DX MkII (if it has 21MP or more), that will be my main camera and the current 1Ds MkIII will be the backup. When the 1Ds MkIII dies or I have an over riding need for 50MP then the 5DS will become the 'backup', studio and product camera.

By the time your 1DsIII dies private, we'll be on the 5Dw

Congrats.  Enjoy the family.

So, with my tongue firmly implanted in my cheek (for those of you on this thread who are international, that is a saying meaning I am trying to be funny and don't mean what I am saying) you actually now have a very useful alibi for your G.A.S.  You really need that new camera equipment to get better photos of the baby!

 ;) ;) ;)

Good thinking JPAZ ! On your advice I've told my wife I need a 5Ds so I can get both mother and baby in focus at the same time !

Sporgon,
Beautiful, something to be proud of, a nice family!
One thing that came into my mind:
Since your daughter sends to you expensive pets shortly after getting it, you might suggest that she should have an 800 mm f/5.6 lens for a pet.  Pretty soon, she'll off load it onto you.  ;D ;D ;D
Hope you have a great time with the grand kid! 8)

Haha, that's a brilliant idea !

Many thanks to all you guys for your encouraging comments ! Here are a couple more from to day; the baby's getting bigger.

First is 50/.4 @ f2 and the second is my ubiquitous 24-105L at about 90mm, f4. Both had fill bounced off the ceiling.

Suddenly the 5DIII looks like much better value !

If this is inexpensive and as good as the pancake lenses, it will be a good addition to the landscape photographer's kit. Let's see: 880 gram Sigma Art 50, vs 200 gram Nifty Fifty III, hauled up 1000 ft elevation, along with tripod, camera, other lenses. If lightweight lens A gives (nearly) as good quality as heavyweight lens B at f/8, lens A is worth a look.

Exactly my thoughts !

Yes, STM is a PITA for manual focusing, which is all I do on landscape shots on-tripod. One can make focus-by-wire (all STM works this way) work, but it takes longer than for a USM or manual focus lens.

Are all STM lenses released so far manual focus by wire ? I presume they must be, but do they have to be ?

If this new lens follows recent STM releases in that it has no distance scale window, then I think I might lose enthusiasm for it. I love the 40mm pancake - except for the fact it has no distance scale. Using BBF I find that this is not normally an issue. However I am unable to see if I have inadvertently focused the lens beyond infinity when trying to shoot at infinity.

Maybe this it it. It could be that this lens is very good. It's easier to make a f/1.8 better than a f/1.4. If this lens was as good as the current 1.4 stopped down across the frame, but better at f1.8, who's going to buy the current f1.4 lens ? If it's a metal mount and case quality similar to the 40 pancake, latest IS prime releases etc, them I'd be more than happy with STM for this type of lens.

You're correct that the mediocrity of the f1.4



Hey, Steady ! The current EF 50 f1.4 is superb from f3.2 to f8 in terms of resolution. One of the lenses that would eat up the new 53 mp sensor at those apertures.

 



However, for me a fast prime is about good bokeh -

 and a smaller filter thread indicates that they didn't put much importance into this.



Well a fast prime for me is all about size, balance and portability.

And what's that last comment all about ? Ever heard anyone complain about the bokeh of a Pentax 50mm f.1.7 takumar ?  ;)

Sometime ago there was a mention that the next 50mm lens would be an IS version of the 1.8 and it would replace both the 1.8 and 1.4.

That's true, although it doesn't look as if this lens will have IS from the rumour so far.


Where in the HE double hockey sticks is the 50 1.4 replacement??

Sigh...

The current EF 50/1.4 uses an aspherical element and two high refractive elements, as well as the modern coating. I'm not sure that is identical to thirty years ago, though the optical formula may be the same.

Makes me wonder if this lens has been the subject of stealth up grades over the years. Anyone know for sure ?

Hopefully, the 50 will be better optimized for wide open shooting.


That's certainly not what I want. The current lens is superb across the frame from about f/3.5 onwards; the new one had better be the same. I expect a small improvement in faster IQ, maybe achievable by not making it so fast in the first place, ie an f/1.8 or 2. How about an f/1.7 just for marketing purposes ?

The 50 1.2L is optimised for shooting open, and you are welcome to it.

None of this makes a lick of sense.

You advocate making 50/1.4 lens slower and/or ignoring its one weakness - wide open IQ? You do realize that optimizing the lens' wide open characteristics does not mean making things worse stopped down.

As for the 50/1.2, it is not optimized for wide open shooting, at least not for any modern sense i.e. sharp center plus sharp across the frame.

Just remind me which lenses are optimised for use wide open.

Don't get a lot of snow in East Yorkshire really. This is about as frozen as it gets.

Seeing as there is all this talk of a new 50 mil I thought I would give my old one an outing.

Canon 135L 2.0 vs Canon 200L 2.8

I'm thinking about buying 1 of those 2 lenses for portrait work but haven't decided which one yet. Has anyone here who already used both of them and know which one is better in Image Quality and Sharpness?

Thank you all for your time :D

I have had them both until recently, and I'd say in practice there is nothing between them. If you're going to be really picky the 135 at f/2.8 is probably a tad sharper than the 200 wide open at f/2.8.

The 200 is cheaper, and even cheaper still used. Agree with marsu42 on the flattering perspective; they are both pretty much the same.

A couple of practical points. The 135 is easier to hand hold and needs less space. Also bear in mind that you could get a 200 f/2.8 and an 85 f/1.8 for the same price as a 135. ( or at least you can here in the UK). 85 is great for half length portraits. I think it's too short for a tight head crop.

Count me in on a new 50. I'll even pay the EAP. My 50/1.4 is a superb lens, but I've never had it fixed since the AF went a bit feeble and hesitant and since dropping it it now has a de centring issue.

Hopefully, the 50 will be better optimized for wide open shooting.
