do image stabilisers decrease image quality?

Yes they do! That's why they sell them at a higher price than lenses that do not have the feature.

I'm still thinking this one over!
I've heard that the 1Ds batteries can cause problems as they get older. Anyone experienced this?
I'm also thinking of swapping the 5Dc for a 5D mk2, but I guess that's a different debate!
The thrill of owning a 1ds mk2 is outweighing a 5d mk2 at the minute!
My only real concern is its low light capabilities. The 5dc barely cuts the mustard in dark wedding venues, will the 1ds mk2 be any better????
Thanks all
Rhys
dr croubie said:a) yes that would be cool. There's already a lot of other T/S adapters for various lenses to Mirrorless systems (i've also got a few for MF lenses to my EF bodies)
b) But 'af passthrough' wouldn't work. AF works by looking at the relative phase-differences of the lightwaves coming through the lens. as far as I know, if the lightwaves aren't coming in at the right angle, AF would struggle (if you've ever used a tilt or shift lens, or lensbaby, you'll know it messes up the light-metering, same deal). But using contrast-detect in live-view works (for light metering at least). so maybe it might work for AF too (the contrast-detect af, not the phase-on-sensor). Still, I don't know what would be the point of a t/s lens with af...
At least being able to pass the aperture-closing signals through would be good, then any EF lens would be a t/s lens (no point on ef-s lenses). I was thinking that might be difficult to keep constant-rotation in the adapter, the wire links can't go around forever. But then I realised that normal TSE lenses so that anyway, so there's probably a way around it...

It's my understanding that bokeh refers only to the quality of OOF blur, not the quantity. Therefore it can be better or worse, but 'more bokeh' is an non sequitur.
the visual quality of the out-of-focus areas of a photographic image, especially as rendered by a particular lens.
One thing to consider is that the Kenko will work with lenses like the 100mmL and the 70-300mmL while the Canon TC either will not mount at all, or only works at certain focal lengths.alben said:Thanks for the info, I had not realised the 2x would be f11 :-[ any preference between the Canon or Kenko, my instinct is to go with the Canon Mk111 even if it is more expensive.

Mt Spokane Photography said:Are you talking the Zeiss 50mm f/1.4? It certainly is not as good optically as the Canon 50mm f/1.4, but has a better build by far. With a wide aperture autofocus lens, its pretty common for the AF to need fine tuning with AFMA for the best results.littlepilotdude said:Mt Spokane Photography said:You did not say what you would use it for, or if you would be a heavy duty user or ligh user. There is not a huge difference in image quality between a cheap 50mm f/1.8 and a $750 lens. For the most part, you are paying for a wider aperture, improved construction, and faster autofocus.
If you are only going to use the lens occasionally, get the Canon 50mm f/1.8. However, if you want to use manual focus one of the others will be better, the Zeiss being much easier to manually focus. However, with manual focus, you run into other issues like the viewfinder size, focus screen type, etc.
Another thing to understand is that lenses perform differently on APS-C and Full Frame bodies. The Sigma 50mm f/1.4 is optimized for Crop bodies, while the Canon 50mm f/1.4 is optimized for use on FF bodies and has better IQ on FF than the Sigma does.
Hello,
I would use this lens quite frequently in all situations. I'm looking for a well constructed lens and good quality. I have used the Zeiss and it was great. I have also used the Canon 50 1.4 and it wasn't as good as the Zeiss. The only one I haven't used is the Sigma. I use a 5D Mark II, so I wouldn't go with the sigma since it isn't great with full frame.
Thanks,
littlepilotdude
Here is a link to comparisons of test data. The Zeiss has less viginetting, but loses by a lot in the other areas.

Here is the timeline I was told
present:
The 7D and 60D will remain current
year 2015 still current
year 2018 new sensor tech announced
year 2025 70D and 7D mkII receive a long awaited upgrade and have digic VI processors and an 18MP hybrid sensor with phase AF for continuos focus in video mode! Also, the power of the new processor will enable 1 full stop better high iso when shooting jpeg.
seems about right to me...
You must be really f_ken bored....to have this type of topic posted
bran8 said:I am wondering if some light could be shed on the max useable print size for landscapes taken with a 5dii/5diii. I have looked over another post on this forum that discussed this topic and have read some of the links provided, but am still left wondering a few things:
1) The link that was given referencing a tutorial on Adorama's website suggested that the print size be limited to the pixel dimensions divided by 135. That would give a roughly 42" x 28" print (rounded up) printed at 240 dpi for the 5d mark ii. My question is, how accurate is that assumption? What if I print at 300 dpi?
2) How much of an advantage does someone using a d800 (or for that matter a 46mp Canon when the time comes) have over someone using a 5dii when printing at say 45" x 30" or 60" x 40"? Anyone with experience printing landscapes from a d800 vs. a 5dii/iii?
3) What do you find the best program is to enlarge landscape photos? I have Perfect Resize 7, but have found that I like the results from CS6 better. I feel that Perfect Resize 7 gives results that look more like a painting (on the screen, I have never printed one of these to a 60" x 40" size, so maybe it looks better than CS6 once it is printed), but I really don't know a lot about the program and only use basic settings. Am I missing something there?
4) I know that a common answer to the question of how large can you print a photo is, "It depends." I would like to get a more specific answer from someone that commonly does print large, high-detail landscape photos. How large are you willing to print landscapes taken with a 5dii/iii?
Thank you in advance for any responses to any of the above questions!
elflord said:If you're shooting indoors a lot, you'll be better served by faster glass
I think I'd benefit from f/1.4 glass as well- it will counter my high ISO problem as well as provide the shallow DoF when I do go FF. But I think a 24mm or 35mm will suit me better indoors. 50mm on a crop is too long. I used to have the 1.4, but ended up selling it and just kept the 50 1.8.dtaylor said:* Finally, for the price and hassle of moving, why not just add a fast prime?
