Lenses / Re: 40mm f/2.8 Wow what a lens
« on: March 26, 2013, 03:41:38 PM »
How are you guys liking this lens compared to the 50mm 1.8 canon? I'd like to get the pancake but if it isn't as sharp or produce comparable images, I feel like it isn't worth it but that is me.
I like the pancake better (build, bokeh, AF), but 50/1.8'II seems to be a little bit sharper at f/2.8 when comparing at 100%.

I think that Sigma has better optics for shooting at f/1.4 and nicer bokeh too. However, for f/2.8 and smaller apertures 40/2.8STM pancake may be a smart choice.

EOS Bodies / Re: Will the 70d have a new sensor?

I just hope to see a new sensor in 7D2 first (Aug-Sep 2013) and then in 70D (may be next year). I don't really care about new crop DSLR, but if Canon puts something interesting into their EOS M successor then I may buy one.

Chasing tack sharp in-camera JPEGs? Forget about it... It's the same as chasing unicorns :).
You must learn a decent RAW processing technique. It is the only way.



Canon General / Re: Gear upgrade: 2 primes vs new body + 1 prime??

You need at least 2 bodies for the job. 5D3 + 85L'II would be my choice.

Before I bought my first DSLR, I've read many beginners guides, reviews and personal opinions. However, now I know that the most popular advices like "buy the lens collection first, camera doesn't matter" or "you don't need FF to start with" are not working for everyone, not for me. So, what I've learned is :
I don't need to cover 8-800mm focal range, like many others do. For me, 3-4 primes is enough.
I do regret that I didn't start with a FF camera. Now I'd choose 5D3+50/1.4 over 7D+24-70L'II.
Zooms for work, primes for pleasure! No more zoom lenses for me :)
If I don't know what I want, then I don't need it :D

Only you can decide whether you need that kit lens or not.


Why are you so sure that it is Sigma's fault? Why not FoCal? or Canon? or the combination of all three? My bet is on FoCal :).

Unfortunatly, no long glass is available yet for micro 4/3 :(
99% (or more?) of long lens use is for sports or wildlife.  Micro 4/3 isn't quite there yet.  The AF systems, while improving, currently isn't suited to this.  For example, its very, very difficult to get a good bird in fight shot.  Most people who can get a decent shot are using old-school manual focus lenses with adapters.  But, the next OM-D should move things up a notch.  Panasonic are also promising something special.  Following that, I'd be surprised if none of the m43 lens manufacturers (and there are 20 or so companies involved) didn't release a decent 200mm (AKA 400mm) or 300mm (AKA 600mm) lens.  After all, the real interest in micro four thirds lenses is in fast primes.

Ignoring arguments about aperture equivalence and sensor noise, an M43 300mm/f4 is going to be a lot more affordable and easier to handhold and use than the Canon 600mm.

I think that cropping in photoshop is cheaper than buying a dedicate crop system just to have something smaller and easier to handhold. For example, cropping (or not) 6D+24-105L images vs. OMD+equivalent lens set (because it is lacking the not-cropping option) - which combo would cost and weight more? :)

Lenses / Re: New wide angle lens for FF

I'm not sure if 24/1.4L'II could be THE landscaping lens. I'd rather get Zeiss 21/2.8, unless you really need that f/1.4 aperture or AF. However, if I had the money, I would go straight for TS-E 24/3.5L'II or TS-E 17/4L (can't use regular filters).
Samyang T-S 24/3.5UMC is coming soon and it may be something worth waiting for. Their 14/2.8UMC (can't use regular filters) has strong and complicated distortion, but all the rest about this lens is just beautiful.
16-35L'II is not perfect corner-to-corner wide-open, but it is pretty competitive at f/5.6+ and its zoom-ability may be a huge advantage for many people. However, I don't find it to be a smart choice as a dedicated landscaping lens.

I'd choose FF+3 lenses over crop+4 lenses.

I forgot to mention that my 3GB paging file is located on the RAM Disk as well ;)

Paging incurs some (but not much) overhead, so if you made your RAM disk 3Gb smaller and allowed the system to directly address that RAM rather than going through a pagefile you'd get better performance. Your method is still faster than hitting a spinning disk, but it does seem a tad… silly.

The thing is that some programs (like older ones, 32bit) require a paging file to operate, so I'm simply cheating :). Otherwise I would just turn it off. I agree, it does seem a tad silly, however, I rarely use more than 7GB of RAM. Normally it is only 5-6GB, which includes ~1GB for web browser, ~1.5GB OS and background services and ~3-4GB for LR and stuff...

Thanks everyone for the advice  :D ;D

Unfortunately this laptop looks nice does not allow upgrade of ram (similar to mac book air). So appears i will have to bit the bullet and go for new system.

Seems to me the key for lightroom system

1) Ram as much as possible
2) processor i7 best that can support lots of ram

Did not know anything about ram disk so have read up. seems interesting if have lots of ram. also came accross this has anyone had any experience with supercache? Seems to be similar to ram disk but mirrors rather than load everything.

Again thanks everyone for your help

I think that supercache is very similar to SSD caching, only using a RAM Disk instead of SSD. This way you are letting the system itself to decide which data needs to be cached. I don't trust the machine :), so I prefer to manage it myself. I tried 5-6 different RAM Disk softwares and decided to go with Primo Ramdisk, because it seems to be the most stable and simple to use (and one of the faster ones). My system is running 24/7 without reboot for many months and I would lose all the data on RAM Disk if the system crashes. It never happened, but I'm using copies nonetheless.
My system:
i7-3770K - because I'm running it 24/7 and it is more power efficient (google Virtu MVP)
GTX 670 - CUDA cores + I like games too
Sabertooth Z77 - just because :)
32GB 1600MHz (4x8GB) RAM
Vertex 4 SSD
10TB external storage

Thanks for the tip my machine currently runs 24/7 so will follow your recomendations, i will also check primo ramdisk

Just remember that Z77/LGA1155 system can only have 32GB of RAM maximum. If you decide to have more, then you need X79/LGA2011 system, which suggests i7-3930K CPU.

P.S. Watercooling isn't really any quieter. I'm using Zalman CNPS12X cooler, which is pretty silent and gives me nice temps from 26C idle to around 40something'C on load.
